S e t u p a n d o p e r a t i o n Motherboard The motherboard contains the various disk controllers and other electronics necessary to control the server’s functions. It contains the memory and first two processors as well as PCI and EISA expansion slots.
S e t u p a n d o p e r a t i o n Caution Caution You must maintain at least 15 cm space around the computer for adequate ventilation. Otherwise damage could result from overheating. Setting Up Your System for the First Time After you have unpacked the server and rolled it into position, use the jacking mechanism on the front castors to immobilise it.
S e t u p a n d o p e r a t i o n Using the Front Panel This section describes the functions of the front panel during normal operation. Caution Caution Do not place any large or heavy objects on the top, especially near to the front facia.
S e t u p a n d o p e r a t i o n Note Note It is good practice to warn anyone who may be accessing the system remotely, i.e. using the SMA from a remote computer via the modem port, before you press the button.
S e t u p a n d o p e r a t i o n ♦ - Pressing this button initialises the modem, which is ONTROL connected to the SMC modem port on the back panel of the server. If the modem initialisation is successful, the LCD displays the code 0000.
S e t u p a n d o p e r a t i o n Note Note When security is enabled and the door locked, you can use the KeyLOC infrared card to unblank the screen and enable the keyboard temporarily. The card will also silence a security alarm.
S e t u p a n d o p e r a t i o n To run the ECU ♦ Locally, press F2 to run the Flash Disk Utility during the hardware boot sequence but before the operating system loads, remotely, run the Flash Disk Utility via the SMA.
S e t u p a n d o p e r a t i o n ECU Help A help box is always available giving basic information on whichever menu item is currently highlighted. More detailed and useful information can be found as a simple tutorial in the first menu item, ‘Learn about configuring your computer’.
S e t u p a n d o p e r a t i o n disk boot process fails. You can also copy files to the Flash Disk, e.g. hardware component configuration (.CFG) files which the ECU uses. If you are using the RAMdrive to enter details of an add-in card, you must remember to update the Flash disk before closing.
U p g r a d i n g a n d E x p a n s i o n UPGRADING AND EXPANSION This chapter explains the procedure for upgrading the CPU to one of higher speed and also provides information on upgrading the memory. You can also install expansion cards to increase your system’s capabilities.
U p g r a d i n g a n d E x p a n s i o n Loosen the floating fasteners, located at the top left and right corners of the panel, until they move in and out freely. These fasteners are mounted in a spring fitting and should not be separated from the panel.
U p g r a d i n g a n d E x p a n s i o n To gain access, it is required to remove the protective metal plate which covers the upper part of the electronics chamber. On completion of any work it is important to replace this panel for airflow integrity.
U p g r a d i n g a n d E x p a n s i o n Caution Caution All electronic computer components are sensitive to static electricity. Always take antistatic precautions before handling such components (see the Appendix for more details).
U p g r a d i n g a n d E x p a n s i o n and ZIF socket are designed to ensure that the processor can only install in the correct orientation. (The pin pattern is totally different at one end.) It will only fit into the socket one way.
U p g r a d i n g a n d E x p a n s i o n Now adjust the processor multiplier and external bus clock speed switches on the motherboard (in conjunction with the new processor’s data sheet), as in the following tables.
U p g r a d i n g a n d E x p a n s i o n The additional CPU board then fits into the same socket, with the processors facing downwards. Fit the metal support strut into place. Hooks at one end fit into the fan housing and the other end is fixed with a screw at the chamber rear.
U p g r a d i n g a n d E x p a n s i o n The following table lists the supported memory configurations. Bank ONE socket 2 must be used first. Bank TWO, when used, must have an identical number of modules.
U p g r a d i n g a n d E x p a n s i o n Taking care to avoid touching any of the components on the DIMM, grip the top corners of the DIMM between thumb and first finger and carefully lift the module out of the socket.
U p g r a d i n g a n d E x p a n s i o n Installing and Removing Expansion Cards Important Note Important Note The procedures explained in this section are for authorised engineers only. The following illustration shows the positions of the expansion card slots in the electronics chamber: Figure 2-11 PCI and EISA/ISA Expansion Card Slots...
U p g r a d i n g a n d E x p a n s i o n Position rules Additional SCSI controllers ♦ These must be fitted in one of the bottom three PCI slots to avoid boot-up conflicts with the onboard controllers.
U p g r a d i n g a n d E x p a n s i o n Removing Unplug all cables connected to the board and remove them completely. Remove the securing screw and pull the board out of the slot, leaving an empty space on the rear panel for the blanking plate again.

T e c h n i c a l i n f o r m a t i o n Description The architecture of your server supports symmetrical multiprocessing (SMP) and a variety of operating systems. The server is equipped with both PCI (Peripheral Component Interconnect) and EISA (Extended Industry Standard Architecture) busses.
T e c h n i c a l i n f o r m a t i o n Memory Server memory is located in two memory slot areas on the motherboard. Fully loaded, these provide 2 Gbytes of common high-speed memory for the server.
T e c h n i c a l i n f o r m a t i o n The server supports both base (conventional) and extended memory. Base memory is located at addresses 00000h to 9FFFFh (the first 640 Kbytes). Extended memory begins at address 100000h (1 Mbyte) and extends to the limit of addressable memory (2 Gbytes).
T e c h n i c a l i n f o r m a t i o n Central Processing Unit The server’s first two CPUs are located on the motherboard. The motherboard has two type 8 ZIF sockets to become either a single or a dual processor board.

P o w e r s y s t e m The power supply is controlled from the Front Panel. It normally operates in one of two modes, Power On or Standby. In Power On mode, unit provides electricity to all its outputs and the system functions normally. In Standby mode, the power supply unit is shut down, but it continues to keep the batteries fully charged, and some of the control signals are still valid.
P o w e r s y s t e m Signal Function AC good Digital output indicates when true that the AC input voltage is suitable and that the PSU is currently powered by the AC input only. Reference for the control interface. Power On input In Standby (with AC input present), connecting this input to 0V until the PSU asserts DC Good, will power up the PSU.
P o w e r s y s t e m This signal is used by the System Management Unit in determining whether the AC supply voltage is sufficient to power the system configuration and in reporting AC supply problems to the user. The signal indicates 0V AC input when the unit is in Power Off mode.

D i a g n o s t i c c o d e s DIAGNOSTIC CODES REFERENCE This lists the diagnostic codes that your server can produce. Some of these codes indicate errors or malfunctions; others are simply way-markers that indicate normal progress.
D i a g n o s t i c c o d e s ♦ Brownout mode (A.nnn) This mode indicates a temporary reduction or even absence of the AC electric power. If full power is not restored after approximately five seconds, Brownout mode will change to Battery mode.
D i a g n o s t i c c o d e s 0F10-0F4F These codes indicate various other errors and could appear on the LCD at any point. The following list defines the codes and indicates what action you should take if these errors occur.
D i a g n o s t i c c o d e s Settings of the MODEMResponseTimeOut and MODEMReceiptTimeOut variables, in the SMA, are correct. 0F41 MODEM port Response time-out - Same as 0F40. 0F42 MODEM port Transmit time-out - Same as 0F40. 0F4D MODEM AT command result code time-out occurred - Indicates faulty modem, modem cable, SMC board or SMC (FPSC) variable settings.
D i a g n o s t i c c o d e s The following codes have special meaning to the SMC: ♦ 0001 is issued, accompanied by an alarm, under the following circumstances: ◊ The nickel-cadmium battery on the SMC board has fully discharged.
D i a g n o s t i c c o d e s POST beep codes Certain tests are performed before the video subsystem is initialised, thus requiring the speaker to emit beep codes in the case of a failure. The following table describes the various codes and their meaning.
