Page 18: Introduction To The High-Performance Server
1 Introduction to the High-performance Server The modular scaleable architecture of your high-performance rack server supports symmetrical multiprocessing (SMP) and a variety of operating systems. The server comes with Peripheral Component Interconnect (PCI) and Industry Standard Architecture (ISA) buses. The server board set consists of eight individual boards.
Page 19: Server Features
AC450NX Rack Server System Product Guide The easy-to-integrate server can easily accommodate the needs of a variety of high performance applications—for example, network servers, multiuser systems, and large database operations. As your application requirements increase, you can upgrade your server with: •...
Page 20 Chapter 1 Introduction to the High-performance Server Server Features (continued) Feature Comment Front panel board The front panel board provides the user interface to the server. The board allows other servers to communicate with this server, even while power is down, via an Intelligent Chassis Management Bus (ICMB). Push-button switches control power-up, reset, and nonmaskable interrupt (NMI) functions.
Page 21 AC450NX Rack Server System Product Guide Server Features (continued) Feature Comment PHP I/O baseboard One 16-bit ISA expansion slot shares a common chassis I/O expansion slot with a 32-bit PCI slot (you can use the shared slot for either ISA or PCI but not both).

Page 34: Obtaining A Power Cord Set
Chapter 2 On-site Installation: Installing the Server Obtaining a Power Cord Set WARNING Do not attempt to modify or use an AC power cord that is not the exact type required. Because a power cord is not supplied for the server, you must obtain a power cord that meets the following criteria: For North America the cord must be UL Listed/CSA Certified, 14/3, 75 °C type SJT with NEMA 6-15P attachment plug and IEC 320, C19 outlet.

Page 37: Booting From The Server Configuration Software Cd
AC450NX Rack Server System Product Guide Booting From the Server Configuration Software CD CAUTION The Server Configuration Software CD contains only a limited operating system. This limited operating system provides enough function to let you boot from the CD and copy and use the utility and manual files from the CD.
Page 38: Copying Configuration Software To Diskettes
Chapter 2 On-site Installation: Installing the Server NOTE If you do not see the CD-ROM menu but see the following message instead, Operating system not found you need to change the “Boot Device Priority” to the CD-ROM. See “Server Won’t Boot From the CD” on page 38 for instructions. Copying Configuration Software to Diskettes When you copy software from the CD onto diskettes, device drivers suitable for several different operating systems are copied onto the diskettes.
Page 39: Server Won't Boot From The Cd
AC450NX Rack Server System Product Guide Server Won’t Boot From the CD It is possible that your server was shipped with the diskette drive or another device set as the first boot device. If so, the server will try to boot from a diskette or other device rather than from the CD we have provided.
Page 40 Chapter 2 On-site Installation: Installing the Server The server should now boot from the CD, displaying a menu bar that includes creating diskettes, diagnostics, reading/printing the manual, and quitting to DOS. CAUTION If the server does not operate as described in this chapter, contact a qualified service technician.

Page 58: System Setup Utility: When To Run
The System Setup Utility (SSU) is on the Server System Configuration Software CD shipped with the server. The SSU provides a graphical user interface (GUI) over an extensible framework for server configuration. For the AC450NX systems, the SSU framework supports the following functions and capabilities: •...
Page 59: What You Need To Do
AC450NX Rack Server System Product Guide The SSU uses the information provided by .CFG files, configuration registers, flash memory, and the information that you enter, to specify a system configuration. The SSU writes the configuration information to flash memory. The SSU stores configuration values in flash memory. These values take effect when you boot the server.
Page 60: Starting The Ssu
Chapter 5 System System Setup Utility: When to Run • Running the SSU Remotely To run the SSU remotely, you must invoke the SSU.BAT file with the /t switch and redirect the text-mode output via BIOS console redirection. The /t switch puts the display in text mode and allows the console to be viewed and controlled via BIOS console redirection.
Page 61: Customizing The Ssu
AC450NX Rack Server System Product Guide Customizing the SSU The SSU lets you customize the user interface according to your preferences. The AF sets these preferences and saves them in the AF.INI file so that they take effect the next time you start the SSU.

If the .CFG file is unavailable, you must manually create it or define the card through the SSU.
Page 65 AC450NX Rack Server System Product Guide Adding and Removing ISA Cards Adding and removing cards through the RCA provides a way for the RCA to run its conflict detection algorithms on the resources requested by the cards. This alerts you to any possible problems with that particular card in the current configuration.

Powering the server on or off • Resetting the server The EMP Console uses three management plug-ins to monitor the server: • SEL Viewer (not available on AC450NX servers) • SDR Viewer (not available on AC450NX servers) • FRU Viewer The EMP Console also has a Phonebook plug-in that can be used to create and maintain a list of servers and their phone numbers.
Page 79: How Emp Console Works
AC450NX Rack Server System Product Guide How EMP Console Works The EMP shares use of the COM 2 port with the system on the server. When the EMP has control of the port, the port operates in command mode. When the system has control, the port operates in console redirect mode.
Page 80: Emp Console Access Modes (Server Configured For Console Redirection)
Chapter 7 Emergency Management Port Console: How to Use Figure 7-2. EMP Console in Redirect State Figure 7-2 shows the EMP Console window in redirect mode with the terminal window. The text that appears on the server monitor displays in the Redirect window. Availability of the various EMP Console features are determined by two factors: the BIOS EMP access mode and whether the server’s COM 2 port is configured for console redirection.

Page 110: Hot-Swappable Power Supplies: Hot Swapping
11 Hot-swappable Power Supplies: Hot Swapping This chapter tells how to hot-swap a server power supply. When the yellow power supply failure LED on the front panel turns on, you can determine which power supply is defective by checking the three status LEDs on the back of each power supply. If a power supply fails, the yellow FAIL LED on the back of the power supply will be on continuously.
Page 111: Hot Swapping A Power Supply
AC450NX Rack Server System Product Guide Hot Swapping a Power Supply In a fully configured server, the power system contains three 750 watt auto-ranging power supplies; one of the power supplies is redundant. If a single power supply fails in the redundant power system, the yellow power supply failure LED on the front panel turns on.

Page 117: Equipment Rack Precautions
AC450NX Rack Server System Product Guide CAUTION Electrostatic discharge (ESD) and ESD protection: ESD can damage disk drives, add-in boards, and other components. This server can withstand normal levels of environmental ESD while you are hot-swapping hard disk drives and power supplies. However, we recommend doing all procedures in this manual only at an ESD workstation.
Page 118 Safety Guidelines Grounding the rack installation: To avoid the potential for an electrical shock hazard, you must include a third wire safety grounding conductor with the rack installation. If the server power cord is plugged into an AC outlet that is part of the rack, then you must provide proper grounding for the rack itself.
