Upgrading The System; Adding Memory - Intergraph Rack-Mount Workstation/Server System Reference Manual

3 Upgrading the System

This chapter describes adding memory, processors, option boards, internal SCSI drives, and external
SCSI drives for all rack-mount systems.
NOTE Refer to Chapter 1 for details on opening the base unit and protecting against electrostatic discharge.
CAUTION Follow all warnings and cautions in servicing instructions. Personal injury and damage to equipment
can occur if documented procedures are not followed.
CAUTION Use an antistatic wrist strap for all servicing procedures to avoid electrostatic discharge.

Adding Memory

You can upgrade memory on the MSMT353 or MSMT359 system board in 32 MB, 64 MB, 128 MB,
and 256 MB increments; and the MSMT378 system board in 32 MB, 64 MB, and 128 MB
increments. RenderRAX systems ship with all eight SIMM sockets populated.
Memory upgrade kits from Intergraph contain two SIMMs and a disposable antistatic wrist strap.
CAUTION System memory modules available from Intergraph have been certified for use with Intergraph
computers at extremes of temperature and system load to ensure reliable performance. System
memory modules available from other vendors may not function properly or reliably in your Intergraph
computer.
To avoid damaging the SIMMs and voiding the warranty, take the following precautions.
u
Do not bend, twist, drop, or otherwise handle the SIMMs carelessly.
u
Do not expose the SIMMs to moisture or extreme temperatures.
u
Do not remove the SIMMs from the antistatic bag until installation.
Follow these SIMM population rules to correctly install the SIMMs.
u
Each bank has two slots. Fill both slots in a bank.
u
Use the same size SIMM in both slots in a bank.
u
After adding or replacing SIMMs, restart the computer. The new memory configuration is
detected automatically.
The following table shows valid memory configurations. Each bank contains two sockets, and both
sockets must be populated. Memory density must be the same in all populated sockets. NP
designates the bank is not populated.
