Maintaining your system

4-2

014–002250–01

If you cannot resolve the problem yourself, contact Data General as
described in the Preface. If the Data General Service Center
determines that a CRU needs replacement, they will send the new
part.

Replacing CRUs

The cables and devices listed in Chapter 2 are external CRUs. You
replace an external CRU by disconnecting and reconnecting one or
more cables. Refer to Chapter 2 for the procedures for adding or
replacing external CRUs.

Internal CRUs are base components and system options that reside
within your computer unit; they include

D

mass–storage devices

D

the system board,

D

the power supply

D

the fan assembly,

D

memory modules

D

an optional expansion CPU complex board

D

a graphics controller (AViiON 550 only)

D

optional I/O expansion boards.

To add or replace an internal CRU, you must remove the cover of
the computer unit.

Chapter 3 describes how to add or replace drives and subsystems
connected to the SCSI connectors on the rear of your computer unit.

CAUTION:

Before attempting to replace or add a CRU, read the section in this
chapter on “Avoiding Electrostatic Discharge (ESD) Damage” so that
you do not damage the replacement or add–on CRU.
