CHAPTER 2 Installation Sites This chapter details the recommended sites and structures and the buildings in which server systems can be installed, and the structures of the computer rooms. Server systems setups can be classified into two broad forms: one in which a server system is installed in a computer room for message collection and distribution processing and perform calculation processing, and one in which a server system is installed conveniently in an office for use as a stand-alone machine or as one...
CHAPTER 2 Installation Sites 2.1.2 Utility services When selecting sites that afford good access to utility services, take the following factors into consideration: Satisfactory availability of electric power No suspension or failure of water supplies, or the availability of alternate measures for water supply ...
2.2 Buildings 2.2.1 Building structures Structural considerations for buildings in which server systems are to be installed are summarized below. (1) Floor strength The floor of the building in which a server system is to be installed should be strong enough to withstand the combined weight of the server and its component devices.
CHAPTER 2 Installation Sites d) Newly constructed buildings If a server system is to be installed in a newly constructed building, it is recommended that loading strength of the floor itself, beam, and column is 4.9 kN/ (100 lbf/ft ) or greater for such computer room. (2) Vibration and earthquake-proofing Recent years have witnessed the emergence of earthquake-free buildings mounted on earthquake-free foundations that absorb the effects of earthquakes and computer...
2.2 Buildings Water leaking due to clogged drainage pipelines on the roof or in the upper floor(s) c) Preventing water leakage from air conditioning facilities Because air conditioning facilities commonly involve the use of water, as in coolant pipelines, humidifying feed water, and water generated as a result of dehumidifying, they would require measures to prevent water leakage.
CHAPTER 2 Installation Sites 2.2.2 Computer room location Things to consider with regard to location of the computer room are summarized below. (1) Operability The computer room should be conveniently located for access to communication with related departments and for data receipt, issue, and relocation. (2) Security From a security standpoint, the computer room should be located on the lower middle floor of a building, rather than the top floor or a basement.
2.2 Buildings The space used for signal and telecommunication lines in the building Recording media storage room Office room needed for systems administration and development Storage rooms for supplies and spare parts Access control room 2.2.4 Facilities Considerations pertaining to facilities are summarized below:...
To this end, the user needs to review the access route from the opening in the building through which the equipment is carried into the computer room where the equipment is to be set up. The Fujitsu shipping coordinator may take a preliminary tour of the access route and conduct consultations with the user beforehand.
Prior consultation with the Fujitsu shipping coordinator is recommended. (2) Computer room entrance and building passages The delivery entrance of the building into which equipment is to be carried in unpacked, the intermediate passages of the access route, and the entrance of the computer room must have the values specified below.
CHAPTER 2 Installation Sites (3) Withstand load and protection of the access route The withstand load of the access route should be large enough to support the mass and transportation activity concerning the server system. At the time of transportation, the floor and wall surfaces along the access route may require protection.
2.3 Computer Room Structure Security and disaster prevention considerations (1) Base floor strength The base floor on which the server system is to be set up must have enough strength to support a raised floor and facilities and equipment, as well as the server system itself. A floor top view with an equipment layout superimposed with equipment weights for each lockers must be presented to the building designer or the building constructor as a means of determining whether the server system can be installed on the floor in...
CHAPTER 2 Installation Sites 2.3.2 Free-access flooring The construction of free-access floors is reviewed with respect to the following items: Raised floor height Strength and surface material of free-access floor panels Opening for server-system-use Installation of floor panels for a building air conditioner Each item is described as follows: (1) Raised floor height Regarding the raised floor height of a free-access floor, the following factors require...
That area of the free-access floor in which a server system is installed requires a floor panel opening, an auxiliary support and a slit floor panel. When Fujitsu receives a free-access floor allocation plan from the user after the finalization of an equipment layout, it will furnish an opening diagram marked with an opening pattern, an auxiliary support position, and a slit floor panel position.
CHAPTER 2 Installation Sites Figure 2.1 shows the outer view of a slit floor panel. Figure 2.1 Slit floor panel d) Preventing the free-access floor from being collapsed because of the opening Horizontal forces applied to the free-access floor during earthquakes or when heavy equipment is carried in could cause the floor panel to shift, depending on the structure of the free-access floor and the shape of the floor panel opening, leading to free- access floor collapse.
2.3 Computer Room Structure The number of floor panels with an airflow control damper or number of airflow control panels required should be determined by the air conditioning facility or the free-access floor construction designer on the basis of the concerned heat load in the room.
CHAPTER 2 Installation Sites (6) Base floor and free-access floor cleaning The base floor and the free-access floor require cleaning before the server system is installed. The following cleaning procedures are recommended, including those for cleaning the free-access floor surface periodically: 1 Remove dust on the surface of the panels.
2.3 Computer Room Structure (2) Prevention of entry of outside air Outside air penetrating through gaps in a window could threaten successful temperature and humidity control of the air conditioning facilities. Moreover, outside air might contain dust and harmful gases. From this standpoint, the windows in the computer room should be made airtight or semi-airtight.
CHAPTER 2 Installation Sites (6) Maintenance outlets The computer room requires maintenance outlets to power instruments for maintaining the server system or to clean the floor. Maintenance outlets should be provided on column or wall surfaces 5 to 7 m (16 to 23 ft) apart at a height of about 30 cm (12 in.) above the floor.
CHAPTER 3 Equipment Layout This chapter describes the items which considerations require for when laying out equipment. Equipment layout deserves special consideration, because it has a significant bearing on the efficiency of system operation and maintenance. Proposed Computer Room Top View A top view of the proposed computer room must be prepared.
CHAPTER 3 Equipment Layout Precautions in Preparation of an Equipment Layout In preparing an equipment layout, take into account hardware constraints, operational considerations, and installation equipment constraints. 3.3.1 Hardware constraints (1) Cable length limitations Each signal cable or power control cable has a limitation on its length. In laying out equipment, be careful not to exceed these limitations.
3.3 Precautions in Preparation of an Equipment Layout Even if a single device has multiple functions, it should be grouped according to the degree to which it can be run with or without manual intervention. Generally, devices may be divided into the following groups: ...
CHAPTER 3 Equipment Layout (5) Acoustic noise A general-purpose server system is generally made up of a mix of equipment, each of which generates its own acoustic noise. Because the acoustic noises from individual equipment may result in a very high noise-level, it is recommended that these equipment be installed in an unattended zone.
Do not simply install a single, high-capacity central air conditioning unit in the computer room or an adjoining air-conditioning room. Considering possible device failures and the need for regular maintenance of air conditioning units, Fujitsu recommends installing multiple small-capacity air conditioning units (having a cooling power between 15 kW and 50 kW) at locations throughout the computer room.
CHAPTER 3 Equipment Layout 3.4.5 Dusting Units that use paper or toner in operation, such as line printers and laser printers, produce dust. The relation between dust-producing devices and device that should be dust-free requires special consideration. For example, dust-free devices can be installed near the air outlet, while the dust-producing devices can be near the air intake.

CHAPTER 3 Equipment Layout Line and Signal Wiring Facilities This section describes line and signal wiring facilities. 3.6.1 Line facilities When line terminal boards and line terminals are installed, they must be located to allow for easy connection with any line units in the computer room. 3.6.2 Signal wiring facilities Signal cabling with devices that are installed outside the computer room requires...
CHAPTER 4 Air Conditioning This chapter describes which items require considerations when laying out air conditioning facilities. Characteristics of Computer Room Air Conditioning Computer room air conditioning is characterized by: Constant temperatures and humidities Air conditioning conditions and capacities ...
CHAPTER 4 Air Conditioning 4.1.2 Air conditioning conditions and capacities The air conditioning system must have the capacity to be able to process the amount of heat dissipated from the computer equipment to cool the computer room. A server generates heat from the Power Supply Unit, semiconductor devices, etc. The system rated or listed capacity of the air conditioning facilities may have been measured for a general office for human beings as specified by the relevant industrial standards or the...
4.2 Styles of Air Conditioner 4.2.1 Direct blowing In the direct blowing setup, air conditioner(s) are installed in the computer room to blow air directly into the room. This setup is economical, permits easy room temperature and humidity regulation, and is less susceptible to dew condensation. Moreover, the air conditioner(s), free from blowing temperature constraints, offer high working efficiency.
CHAPTER 4 Air Conditioning An air conditioner installed in the duct blowing setup should include a cooling coil, a heater for the winter and temperature control, a humidifier, and a filter. Figure 4.2 shows a schematic view of the duct blowing setup. Figure 4.2 Duct blowing setup 4.2.3 Underfloor ventilation...
4.2 Styles of Air Conditioner This setup features the ability to keep operators less chilled because this lessens direct exposure to drafts of air blown out of the air conditioner. Because underfloor ventilation blows air directly against equipment, the air must be filtered for dust by the air conditioner beforehand.
CHAPTER 4 Air Conditioning Sometimes the underfloor-ventilation air conditioner does not perform heating and humidifying but only cools the room air to the target temperature. In this situation, regulation of the temperature and humidity of the air in the room and under the floor can be accomplished by heating and humidifying the room air and the outside air after it has been dehumidified by overcooling by the underfloor air conditioner.
4.3 Air Conditioning Conditions 4.3.2 Recommended temperatures and humidities for computer rooms Keep the ambient temperature in the computer room at a level that feeds comfortable to the human body or somewhat lower. This precaution will not only prevent local temperature rises in the computer room, such as those caused by equipment which requires high heat dissipation, or stagnant air circulation, but will also allow some time before the upper-limit temperature is reached even if the air conditioner fails.

CHAPTER 4 Air Conditioning (2) Lowering the underfloor temperature In unattended areas where paper is not used and where only those devices that have broad permissible underfloor and room temperature and humidity ranges are installed, the underfloor temperature may be lowered. As an example, in an unattended room associated with a large system installation involving multiple computer rooms, hold the underfloor relative humidity to 70% or below to keep the room humidity at a lower level.
4.3 Air Conditioning Conditions 4.3.4 Dust (1) Airborne dust Ensure that airborne dust does not exceed 0.15 mg/m (0.004 mg/ft ). Most server systems are designed to withstand this level of airborne dust. This is the same as the permissible level for airborne dust in a general office and should be easily attainable in a computer room where there is little inflow of outside air and smoke.

CHAPTER 4 Air Conditioning Precautions Pertaining to the Installation of Air Conditioners Air conditioners that are installed in computer rooms differ in many ways from those installed in general offices. Precautions specific to installing air conditioners in a computer room are summarized below. 4.5.1 Humidifier The reason a humidifier is needed, types of humidifiers available, and humidifiers...
4.5 Precautions Pertaining to the Installation of Air Conditioners (3) Humidifiers used with underfloor-ventilation air conditioners Certain types of underfloor-ventilation air conditioners have a boiling humidifier and a draft fan installed at adjacent locations such that drops of boiling water from the humidifier can enter the draft fan for aerial dispersion.
CHAPTER 4 Air Conditioning 4.5.3 Installing temperature/humidity sensors Temperature/humidity sensors used to regulate the temperature and humidity of an air conditioner are installed at different positions according to the ventilation method. (1) Location of temperature/humidity sensors for a room air conditioner Location to install temperature/humidity sensors for a room air conditioner is: ...
4.5 Precautions Pertaining to the Installation of Air Conditioners 4.5.5 Preventing dew condensation in underfloor ventilation In underfloor ventilation, provisions should be made to prevent dew condensation inside and outside of devices installed in the computer room as they are exposed to direct drafts of cold air from the air conditioner.
CHAPTER 4 Air Conditioning When temperature reaches the target range, turn on the server system. The humidifier may operate after the room temperature reaches a stable state. (3) Example of stopping humidifier upon starting up of the server system In underfloor ventilation, if heat dissipation from server system during startup of the equipment leads transition of drive condition of the air conditioners, and the room is dampened heavily so that the room is brought to high humidity, dew condensation may be caused in the server system.
4.5 Precautions Pertaining to the Installation of Air Conditioners 4.5.7 Installing a backup unit It is recommended that the air conditioner be backed up. Without a backup unit, if the air conditioner fails, the resultant rise in the computer room temperature would demand a shutdown of the server system to correct the failure.
CHAPTER 5 Electromagnetic Environment and Static Electricity This chapter explains the electromagnetic environment conditions and electrostatic effects relevant to server systems.

CHAPTER 6 Power Supply Facilities This chapter deals with input power requirements, power supply facilities, uninterruptible power supplies (UPS), grounding, distribution panels, distribution lines, and the share of responsibility for construction work. Operational stability of a server system requires a good-quality power supply. Power supply facilities that match the power requirements of the server system must be selected to suit the importance of the server system's operation.
6.2 Power Supply Facilities Power Supply Facilities Select power supply facilities after considering the input power requirements of the server system (see Section 6.1), the availability of a power source at the installation site, and the operational importance of the server system. 6.2.1 Kinds and uses of power supply facilities Power supply facilities are used for converting voltages, reducing leakage current,...
CHAPTER 6 Power Supply Facilities (1) Reduction in leakage current Computers are equipped with a line filter in their power input terminals to absorb both external and internal electric noise. If a common commercial power source is connected to a computer, leakage current will flow to the grounding cable of the computer.
6.2 Power Supply Facilities 6.2.2 Selecting power supply facilities Select power supply facilities to suit the available power source at the installation site, and the operational importance of the server system. (1) Systems that cannot tolerate service disruption a) Power failure-free system Use of a UPS is mandatory for server systems that cannot tolerate service disruption at any time even the instantaneous interruption or power failure of commercial power supply.
CHAPTER 6 Power Supply Facilities (2) Systems that can tolerate a service disruption If a server system can tolerate a service disruption caused by power interruption or voltage variation, install a transformer dedicated to that system, isolated from the secondary terminals if the system runs at 200 V or grounded to a neutral phase wire if it runs at 400 V.
6.2 Power Supply Facilities b) Transformers dedicated to 400 V server systems Table 6.4 describes the types of high-to-low-voltage transformers that can be dedicated to 400 V server systems and those that can be shared with other power supplies. Table 6.4 Transformers dedicated to 400 V server systems Transformer Case dedicated to a server...
CHAPTER 6 Power Supply Facilities UPS Requirements An Uninterruptible Power Supply system (UPS) supplies power to server systems constantly under power failures even in a huge magnitude of power failures. Instantaneous voltage drop of commercial power generally occur by thunder. The chance of occurrence of instantaneous voltage drop depends on the location of the site (in Japan, three to four times in a year).
6.3 UPS Requirements (1) UPS load specifications Some server systems adopt condenser-input type rectifier circuit (commutating load) as shown in Figure 6.3. Figure 6.3 Commutating load circuit Rectifier of this type turns the current waveform of a server system into a distorted waveform containing harmonics.
(5) Life-span of a UPS built-in battery The main type of battery built into a UPS is a lead-acid battery. Lead-acid batteries have their own life-spans, and therefore Fujitsu recommends a service support agreement for immediate battery replacement. (6) Discharge of UPS built in battery Once a lead-acid battery is completely discharged, sufficient voltage cannot be generated even when recharged.
6.3 UPS Requirements (7) Requirements for power interruption The following specifications must be checked for selection of a UPS. Most of UPS cannot be started up under circumstance of power interruption. If such startup is required, request the UPS manufacturer for modification. ...

6.4 Grounding 6.4.1 Grounding equipment in the computer room For grounding equipment, connect a protective grounding conductor to the dedicated grounding electrode. Transformer Flow of leakage current Line filter Protective grounding conductor Secondary single Equipment wire ground of the transformer Figure 6.4 Method of grounding equipment If possible, do not connect an equipment cabinet to the ground built into the floor of the computer room (such as a mesh ground) through a separate wire.
(the main grounding terminal). If there is no way other than branching from the omnibus grounding cable nearest to the server systems, please consult with Fujitsu Facility section because noise countermeasure which requires expertise is required in most cases. Primarily, the wiring of grounding trunk cable must be implemented by the metal conduit installation method using special insulated cables.
6.4 Grounding 6.4.2 Grounding other equipment Table 6.6 summarizes the requirements for other equipment grounding facilities. Table 6.6 Requirements for other equipment grounding facilities Item Requirements Grounding electrode • A dedicated grounding electrode for other equipment is recommended. If a dedicated grounding electrode is not available, a grounding trunk cable may be branched from a shared grounding electrode.
CHAPTER 6 Power Supply Facilities 6.4.3 Grounding LAN devices Grounding LAN devices which share the same signal ground to the same grounding system and those which have different signal ground to different grounding systems. The method for grounding LAN devices, details of the separation of the LAN transmission line signal ground from the connected devices, and typical modes of LAN connection and grounding are described below.
6.4 Grounding Figure 6.5 Typical 100 Base-T connection 6.4.4 Grounding-plate method In shared ground facilities complying with the International Electrotechnical Commission (IEC) standards, noise generated by other electronic facilities such as electronic devices, air conditioning facilities and elevators may penetrate the server systems through the shared ground facilities' cables.
A circuit breaker must be used in each branch circuit in the distribution panel. Information about the number of branch circuits and circuit breaker capacitance is available from Fujitsu. A UPS over-current alarm could be issued if many components are turned on at the same time.
CHAPTER 6 Power Supply Facilities 6.5.3 Distribution panel structure A distribution panel uses an output terminal strip to connect a power cable to each device. Figure 6.7 Figure 6.8 show typical distribution panel setups having output terminal boards. Figure 6.7 Distribution panel (free-standing) Figure 6.8 Distribution panel (wall-mounted) The distribution panel structures and output terminal boards are described below: (1) Output terminal board position...
6.5 Distribution Panels (2) Distribution panel front plate The front plate must be removable to allow for cable connection to the output terminal boards. (3) Connected device marking A card holder is provided near each breaker to indicate the name of the associated device.
CHAPTER 6 Power Supply Facilities Round crimp terminal dimensions L, W, and d are shown in Figure 6.9. Figure 6.9 Round crimp terminal dimensions (5) Space around output terminal boards The space around output terminal boards must meet the requirements illustrated in Figure 6.10.
6.6 Distribution Lines (6) Grounding connection within a distribution panel Figure 6.11 shows grounding connections within a distribution panel. Figure 6.11 Grounding connections within a distribution panel Distribution Lines The construction of distribution lines requires consideration of induced noise control and voltage drops.
Computer Room The share of responsibility for construction are : Fujitsu will install wiring from the output terminal block in the distribution panel to individual devices in the same room as a standard construction. The construction of all other electrical requirements is the user' s responsibility.
6.8 Distribution Line Insulation Testing Distribution Line Insulation Testing This section specifies the test voltage for distribution line insulation testing and explains the points to watch when performing phase and grounding cable insulation tests and interphase insulation tests. 6.8.1 Test voltage Use an applied test voltage within DC250 V for distribution line insulation testing.
CHAPTER 6 Power Supply Facilities (2) Interphase insulation test from the distribution panel to a directly connected device An interphase insulation test may not be performed on a power cable that directly connects a device to the distribution panel. If interphase insulation testing of a direct power cable is required, disconnect the device and power cable from each other.
CHAPTER 7 Protection Against Lightning If a low-voltage distribution cable that feeds power directly to devices or an interface cable is to be laid outdoors, safeguards are needed to protect against possible destruction caused by lightning surges. If a device is damaged by a lightning, the direct cause is a surge (abnormal voltages and currents).
CHAPTER 7 Protection Against Lightning Protection of AC Line The surge protection level of Fujitsu M10/SPARC Servers, SPARC Enterprise and PRIMEQUEST power supply facility complies to the International Electrotechnical Commission (IEC) standard. Therefore, special protective action against typical multitude of lightning is not required. However, depending on the multitude of induced surge energy, the equipment may be damaged by the induced surge.
7.1 Protection of AC Line (2) Install a surge absorber in each terminal outlet Figure 7.1 shows the surge absorber connected to commercial power outlet. This type is dedicated to single terminal. Applicable for all components using commercial power outlet. Figure 7.1 Surge absorber (power outlet connected type) (3) Install a surge absorber to the input side of a distribution panel Figure 7.2...
CHAPTER 7 Protection Against Lightning Protection of Signal Lines (1) External modem is in use When modems are installed, damage to internal circuitry components in the modems could result from indirect strike surges. Hence, it is recommended to install the appropriate surge absorber.
CHAPTER 8 Security Actions With more sophisticated and extensive use of servers, concern over the security of server systems has become increasingly important. In an online application, for example, a disruption of the central system would degrade or shut down the functionality of the terminals, which could have social or economic consequences depending on the nature of the application.
CHAPTER 8 Security Actions 2 If a disaster occurs, services are closed down, but can be resumed immediately when the disaster is over. Services are closed down temporarily to protect against errors or malfunctions that might arise from continuing to run the server system for the duration of the disaster, or from problems in running associated facilities.
8.2 Details 8.1.3 Kinds of disasters Different kinds of disasters require different security actions suited to their causes and characteristics. Fires Negligence, leaks, catching fire from flare, arson, etc. Earthquakes Overturns, falls, movement, breakage, etc. Water damage Floods, rainwater leaks, supply/drainage pipe leaks, leaks from facilities which use water, water for extinguishing fires, etc.
CHAPTER 8 Security Actions It is also important to train and prepare staff to fight fires before they become too serious. While the Fire Services Law and other relevant regulations dictate that certain fire- fighting equipment be available, this equipment is not necessarily adequate for server system security.
8.2 Details (2) Kinds of fire extinguishing agents Ideally, any fire extinguishing agents to be used in the computer room and the data storage room should not contaminate the equipment or storage media, be harmless to the human body, and be environmentally friendly. Table 8.1 lists fire extinguishing agents and their characteristics.
CHAPTER 8 Security Actions b) Fixed fire extinguishing equipment Fixed fire extinguishing equipment includes sprinklers and carbon dioxide fire extinguishing equipment. A sprinkler, normally tripped on detecting heat, is not suitable for extinguishing fires in their early stages, but can be useful as a last resort for putting out fires. A preaction sprinkler is recommended, because a sprinkler that is constantly filled with water is liable to spray water accidentally upon contact.
8.2 Details (5) Other considerations for fire prevention Other major considerations for fire prevention are: Risks of fires spreading from neighboring buildings Fire resistance of the building Fire resistance of the computer room and the data storage room ...
Hence, earthquake control should be matched to the earthquake motion conditions of the floor on which the server system is erected. For detail of an earthquake preparedness, consult with the construction department of Fujitsu. 8.2.3 Water damage Water damage to server systems, power supplies, and air conditioners often results from leaks.
8.2 Details (3) Water leaking from supply/drainage pipes If a new building is to be built, avoid the construction of supply/drainage pipes around the computer room and the data storage room or limit such construction to a minimum. If piping cannot be rerouted in an existing building, install a stop valve at a point just before the pipes enter the room.
CHAPTER 8 Security Actions 8.2.4 Burglary Disasters caused by malicious acts, such as subversive activities, burglary, and obstructive activities, require protection, because these acts are entirely unpredictable. (1) Environmental maintenance To keep unauthorized personnel away from the building or the computer room, ideally, keep the spaces surrounding the building and the computer room clear of obstacles for good visibility, and maintain a monitoring plan and alarms to detect any trespassers immediately.
8.2 Details (4) Monitor cameras Install monitor cameras in an inconspicuous manner at the entrances to the building, the computer room, etc. for monitoring in the guard room or a monitoring center. (5) Automatic burglar alarms Install automatic burglar alarms at emergency exits or equipment delivery doors that are not in daily use.
