[. . . ] 2. Do not remove any system component from its packaging unless you are ready to install it. Wear a wrist grounding strap before handling electronic components. Wrist grounding straps are available at most electronic component stores. DO NOT attempt the procedures in the following sections unless you are confident of your capability to perform them. Otherwise, ask a service technician for assistance. 1-8 User's Guide 1. 5 Installing a VGA Daughter Board The system board comes with a video controller, a video connector, and a VGA daughter board. [. . . ] Refer to Table 1-1 for the jumper settings. System Board 1-11 1. 7 Memory Upgrade The six 72-pin SIMM sockets onboard support both Extended Data Output (EDO) and fast-page mode SIMMs. You may install 4-MB and 16-MB single-density as well as 8-MB, and 32-MB double-density SIMMs for a total of 192-MB system memory. The SIMM sockets also support 64-MB SIMMs, when available, to achieve 384-MB system memory. 1. 7. 1 Rules for Adding Memory · · · Use only the same type of SIMM in a given bank You may combine different types of SIMMs for a particular memory configuration as long as the SIMMs in each bank are of the same type. For example, for a total memory of 16 MB, install two 8-MB SIMMs into the sockets marked SI6 and SI5 (bank 1) or SI2 and SI1 (bank 3). You can not use a 16-MB SIMM alone for a 16-MB memory. Always install SIMMs starting from an inner socket. For example, install SIMMs in socket SI6 before in socket SI5, or in socket SI2 before socket SI1. Always remove SIMMs starting from an outer socket. For example, remove SIMMs in socket SI5 before in socket SI6, or in socket SI1 before socket SI2. · · 1-12 User's Guide 1. 7. 2 Memory Configurations Table 1-3 lists the available memory configurations.

You can use other combinations as long as you follow the rules for upgrading memory. See section 1. 7. 1. System Board 1-13 1. 7. 3 Installing a SIMM Follow these steps to install a SIMM: 1. Locate the video DRAM upgrade socket labeled U44 on the system board. Gently insert a 514260ASL (256K x 16, 70ns SOJ) chip into the upgrade socket. Make sure that the pin 1 indicator on the chip matches the notched corner of the socket. Pin 1 Indicator Notched Corner Figure 1-10 Installing a Video Memory Chip 1-18 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 Using the SCSI Feature Follow these steps to use the SCSI feature: 1. Install a SCSI device in the system and connect it to the SCSI interface on the system board. Refer to Table 1-1 for the jumper settings. Enter the BIOS utility to set the corresponding SCSI parameters. Enter the SCSI Setup utility and make the necessary changes. Refer to the SCSI manual for more information. For more information about the installation procedures under different operating systems, read the README. XXX in the subdirectory of the target operating system. System Board 1-19 1. 11 1. 11. 1 Server Management Features Remote Diagnostic Management The Remote Diagnostic Management (RDM) is a network management tool that utilizes modems and telephone lines to control a host of servers from a remote station. It monitors and analyzes the server condition, updates the BIOS settings if necessary, or reboots the server in the event of failure and quickly return it to normal operation. This capability to execute the RDM program from a remote site bridges the distance barrier in fixing server problems and reduces wasted time due to system failure.

System Board 1-23 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. [. . . ]
