[. . . ] The system board supports two optional features, the ASM Pro and the remote diagnostic management (RDM), that allow better server System Board 1-1 management. The ASM Pro detects problems in CPU thermal condition, CPU working voltage detection (±12V/±5V/3. 3V/1. 5V), and PCI bus utilization calculation. It also detects if the CPU fan or the chassis fan malfunctions. The RDM allows execution of the RDM diagnostic program from a remote RDM station to fix detected problems or to reboot the system. 1-2 User's Guide 1. 2 · · · · · · · · · · · Major Components Exclusive slots for two Intel Pentium II processors Memory banks (Bank 0 to Bank 3) composed of four 168-pin DIMM sockets Two ISA and four PCI expansion slots (including one PCI/ISA shared slot) 256-KB Flash ROM for system BIOS 50-pin Fast SCSI-II and 68-pin Wide SCSI interfaces RDM connectors ASM controller chipset Enhanced IDE hard disk and diskette drive interfaces Power connector for 250-watt switching power supply System controller chipsets External ports: · · · · · · USB connector Parallel port Serial port 1 Serial port 2 PS/2-compatible keyboard port PS/2-compatible mouse port The system board has the following major components: System Board 1-3 1. 2. 1 System Board Layout 2 1 3 4 5 6 7 20 19 18 17 16 15 11 14 13 12 10 9 8 1 2 3 4 5 6 7 8 9 10 DIMM sockets Pentium II CPU slot 1 Pentium II CPU slot 2 Accelerated graphics port (AGP) interface slot Primary IDE connector Secondary IDE connector RDM connectors Battery Narrow SCSI connector Wide SCSI connector 11 12 13 14 15 16 17 18 19 20 ISA slots PCI slots BIOS Diskette drive connector PS/2 keyboard port PS/2 mouse port Serial port 1 Parallel port Serial port 2 USB connector Figure 1-1 System Board Layout 1-4 User's Guide 1. 3 1. 3. 1 Jumpers and Connectors Jumper and Connector Locations Figure 1-2 shows the jumper locations on the system board.

Locking a Narrow Clip End Repeat step 3 to lock the other clip. 1-12 User's Guide 1. 6 Installing a Pentium II Processor Follow these steps to install the Pentium II processor to the socket on the CPU board. Place the retention mechanism over the processor socket on the CPU board. Secure it with the screws that came with the package. Figure 1-7 2. Installing the Pentium II Retention Mechanism With the processor module golden fingers pointing downward, align the processor to the posts of the retention mechanism then lower it down. The golden fingers of the Pentium II module is slotted such that it only fits in one direction. Make sure that module groove matches the one on the processor socket. System Board 1-13 3. Press down the processor module until the golden fingers completely fit into the socket. Figure 1-8 4. Installing a Pentium II Processor Press the latches on the sides to lock the processor module into place. Figure 1-9 Securing the Pentium II Processor 1-14 User's Guide 1. 7 1. Removing a Pentium II Processor Unlock the latches the secure that processor module. Follow these steps to remove the Pentium II CPU module from the slot. Figure 1-10 2. Unlocking the Module Latches Firmly hold the processor module and pull it out of the socket. Figure 1-11 Removing the Pentium II Processor System Board 1-15 1. 8 Memory Upgrade The four 168-pin sockets onboard support both extended data output (EDO) and SDRAM-type DIMMs. You may install 16-MB, 32-MB, 64-MB, or 128-MB DIMMs for a maximum of 512-MB system memory. Each of the sockets represents one independent bank. This allows you to install DIMMs with different capacities to form a configuration. 1. 8. 1 Memory Configurations Table 1-4 lists some system memory configurations. You may combine DIMMs with various capacities to form other combinations.

Connect the "wake-up on LAN" cable from CN27 on the system board to CN2 on the card. Figure 1-15 Installing the VGA/LAN Combo Card 1-24 User's Guide 1. 10 SCSI Feature The system board features a single-chip SCSI host adapter that adds SCSI I/O capability to the system. The chipset consists of an onboard microcontroller, bus master interface controller, and SCSI controllers. A 50-pin Fast SCSI-II interface with 10 MB/s transfer rate and a 68-pin Wide SCSI interface that transfers at 20 MB/s (Wide SCSI) and 40 MB/s (Ultra SCSI) are also onboard to accommodate various SCSI devices. 1. 10. 1 1. 3. Using the SCSI Feature Follow these steps to use the SCSI feature: Install a SCSI device in the system and connect it to the SCSI interface on the system board. Enter the BIOS utility to set the corresponding SCSI parameters. Enter the SCSI Configuration Utility and make the necessary changes. Refer to Chapter 3 for information on the SCSI Configuration Utility. There are two general types of error messages: · · Software System 1. 12. 1 Software Error Messages Software error messages are returned by your operating system or application. These messages typically occur after you boot the operating system or when you run your application. If you receive this type of message, consult your application or operating system manual for help. 1. 12. 2 System Error Messages A system error message indicates a problem with the computer itself. A message of this type normally appears during the power-on self-test, before the operating system prompt appears. Table 1-8 lists the system error messages. 1-28 User's Guide Table 1-8 System Error Messages Message Action Replace the battery or contact your dealer. [. . . ] Real-time Clock Error Run Setup. 1-30 User's Guide 1. 12. 3 Correcting Error Conditions As a general rule, if an error message says "Press F1 to continue, " it is caused by a configuration problem, which can be easily corrected. An equipment malfunction is more likely to cause a fatal error, i. e. , an error that causes complete system failure. Here are some corrective measures for error conditions: 1. You must know the correct configuration values for your system before you enter Setup, which is why you should write them down when the system is correctly configured. [. . . ]
