4. Open the front adapter-retention bracket and remove the rear adapter-retention
bracket from the PCI-X slots (see “Installing and removing an adapter” on page
31 for instructions). You might also have to remove longer adapters for access
to the SCSI connectors on the system board.
5. If you are removing an existing SCSI cable:
a. Remove the standoff screws securing the cable to the chassis.
b. Disconnect the cable from the system board connector.
c. Remove the cable.
6. To attach the cable, connect the SCSI signal cable end labeled “PLANAR” to
the connector for SCSI channel B on the system board. See “System-board
internal connectors” on page 77 for the location of the SCSI channel B
connector.
7. Route the SCSI cable between the chassis and PCI-X slot 5 to the back of the
computer. Make sure the cable does not block the flow of air to the
microprocessors or hard disk drives.
8. Attach the external connector to the rear of the computer.
v
If the external end of the SCSI cable has a standard SCSI connector,
complete the following steps:
a. Remove the SCSI-connector knockout from the rear of the computer.
b. Insert the external SCSI connector on the SCSI cable into the knockout
opening and secure it with the attached screws.
v If the external end of the SCSI cable has an expansion-slot cover with an
embedded connector, complete the following steps:
a. Remove an expansion-slot cover from an available PCI-X slot.
b. Insert the expansion-slot cover with embedded connector into the slot
opening.
9. Replace any adapters you removed in step 4. Close the front adapter-retention
bracket and replace the rear adapter-retention bracket.
10. Replace the support bracket (see “Replacing the support bracket” on page 29).
11. Replace the cover (see “Replacing the side cover” on page 27).
12. Reconnect the external cables and power cords. Turn on the attached devices,
and turn on the computer.
13. Use the SCSISelect program to configure SCSI channel B (see the User’s
Guide on the IBM IntelliStation Documentation CD).
Replacing the battery
Important: In servers containing the optional microprocessor board, the battery
must be replaced by a trained servicer who is familiar with IBM products.
When replacing the battery, you must replace it with a lithium battery of the same
type from the same manufacturer. To avoid possible danger, read and follow the
safety information in Appendix B, “Safety information,” on page 117.
To order replacement batteries, call 1-800-426-7378 within the United States, and
1-800-465-7999 or 1-800-465-6666 within Canada. Outside the U.S. and Canada,
call your IBM marketing representative or authorized reseller.
Note: After you replace the battery, you must reconfigure the computer and reset
the system date and time.
