Chapter 5
Upgrading the System
You can upgrade your system by adding memory, additional disk drives, tape
drives, and option boards. You can also replace an existing disk drive with a
larger capacity drive.
Open the base unit, avoid electrostatic discharge, and attach an antistatic
wrist strap as described in Chapter 3, “Opening and Closing the Base Unit,”
before upgrading the system.
Adding Memory
Note:
If you purchase memory from a source other than Intergraph, the
SIMMs must be no more than 1.4 inches high, or they will not fit.
Other specifications for memory include: 72-pin, single- or double-
sided 5 volt, 70 ns, fast page mode, n
x
36 (where n is the density in
MB), DRAM SIMM.
Intergraph’s memory upgrade kit contains two Single Inline Memory
Modules (SIMMs) and a disposable antistatic wrist strap. To avoid
damaging the SIMMs and voiding the warranty, take the following
precautions.
♦
Do not bend, twist, drop, or otherwise handle the SIMMs carelessly.
♦
Do not expose the SIMMs to moisture or extreme temperatures.
♦
Do not remove the SIMMs from the antistatic bag until installation.
