System Board
1.1
Features
The system board consists of the I/O subsystem for the M9L system.
It contains an exclusive connector for the CPU board that comprise the
host subsystem.
This high-performance 64-bit system board utilizes both the ISA and
the PCI local bus architecture. Two ISA and five PCI bus slots reside
on the board to allow installation of either master or slave devices.
A 50-pin Fast SCSI-II interface and two 68-pin Wide SCSI interfaces
come with the system board to connect SCSI devices. External I/O
interfaces include a parallel port and a video port, RJ-45 and two USB
connectors, and keyboard and mouse ports.
The system board supports two optional features, the ASM Pro and
the remote diagnostic management (RDM), that allow better server
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.

Page 7: Esd Precautions
ESD Precautions Always observe following precautions before installing a system component: Do not remove a component from its antistatic packaging until 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. -
Page 8: Video Memory Upgrade
Video Memory Upgrade Larger video memory allows you to display higher resolutions and more colors. The system board comes with a 1-MB video memory onboard upgradable to 2 MB. Follow these steps to upgrade the video memory: Locate the video DRAM upgrade sockets labeled U36 and U37 on the system board. - Page 9 ASM Pro The ASM Pro is a server management tool based on the Simple Network Management Protocol (SNMP). It detects server problems related to the CPU thermal condition, 5V/3.3V/1.5V detection, or PCI bus utilization calculation. This feature is designed primarily for server supervisors and management information system (MIS) personnel to help them detect errors or potential trouble spots in their network servers through a single management station.

Remote Diagnostic Management Remote Diagnostic Management (RDM) 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. -

Page 14: Correcting Error Conditions
1.9.3 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.
