Publication 6181-6.0
These instructions describe how to install the optional 5.25-in. drive
expansion bay (6189-EXPBAY) on the 6181 Computer. The expansion
bay can be used to house additional components such as a CD-ROM
drive.
Installing the expansion bay involves the following procedures:
•
Removing the existing back cover
•
Exchanging the IDE ribbon cable used for the existing hard drive
with the new cable required for the expansion drive option
•
Installing the drive in the expansion bay
•
Installing the expansion bay as the new back cover
To exchange the hard drive and floppy drive cables:
1. Disconnect power from the 6181 Computer.
ATTENTION: Disconnect all power from the 6181
Computer before adding or removing components.
Failure to disconnect power could result in severe
electrical shock or damage to the 6181 Computer.
2. Remove the back cover and top cover of the 6181 Computer. Refer
to procedures in Chapter 4 for details on how to remove the back
cover and top cover.
3. Partially remove the CPU card, I/O card, and any add-in boards so
that you can access the IDE connector that connects to the hard drive
and floppy drive. Refer to procedures in Chapter 4 for details on
removing add-in cards.
4. Disconnect the IDE ribbon cable from the CPU card that leads to the
hard drive and floppy drive and connect the replacement IDE ribbon
cable.
