7. Disconnect the internal SCSI cable from SCSI connector A (J44) or B (J51) on
the system board. See “System-board internal cable connectors” on page 45
for the location of the SCSI connectors.
Note: The SCSI cables that come with your server can only be used with the
integrated SCSI controller with RAID capabilities. If a RAID controller
other than the ServeRAID-5i isinstalled, you must use SCSI cables that
are compatible with that controller. To select and order the correct
cables for use with your RAID controller, contact your IBM reseller or
IBM marketing representative.
8. Reinstall the adapter-support bracket in the server (see “Removing and
installing the adapter-support bracket” on page 54).
Important: To ensure proper cooling and server operation, you must keep the
air-baffle cover closed.
Note: You must reinstall the air-baffle assembly when you reinstall the
adapter-support bracket. Make sure that no cable is under the
adapter-support bracket or interferes with the center fans (connector
J18).
9. Reinstall the plastic dividers between the Active PCI-X adapter slots.
10. Reinstall the adapters that you removed. If you have not yet installed the
ServeRAID controller, install it now.
See “Installing a hot-plug adapter (slots 5 and 6)” on page 59 or “Installing a
non-hot-plug adapter (any slot)” on page 61 for instructions for installing a
hot-plug or non-hot-plug adapter; then, return to this step.
11. Replace the SCSI cable on the SCSI backplane with the SCSI cable for your
new ServeRAID controller. The SCSI cable being replaced was one of the
cables that was disconnected from the system board in step 7.
12. Route the free end of the SCSI cable from the SCSI backplane through the
adapter-support bracket opening and toward the ServeRAID controller (see the
illustration in step 13).
13. Attach the free end of the SCSI cable to the selected internal SCSI channel
connector on the ServeRAID controller. Make sure that the other end of the
SCSI cable is attached to the connector on the SCSI backplane.
Attention: When you route the SCSI cable, do not block the ventilated space
around any of the fans.
The following illustration shows how to route one SCSI cable to the ServeRAID
controller.
