2. Cable identifiers are printed on the cables that come with your server and
options. Use these identifiers to connect the cables to the correct connectors.
For example, the hard disk drive cables are labeled "HDD option."
Complete the following steps to cable the ServeRAID controller:
1. Determine the number of SCSI channels that you want to use on the
ServeRAID controller.
2. Review the information in "Safety" on page v, "Installation Guidelines" on
page 9, and "Handling static-sensitive devices" on page 10.
3. Turn off the server and disconnect all power cords and external cables
("Turning off the server" on page 12); then, remove the server cover (see
"Removing the server left-side cover and bezel (tower model)" on page 15 or
"Removing the server top cover and bezel (rack configuration)" on page 17).
4. Lift the adapter-retention clip on top of the adapter-support bracket; then,
remove the full-length adapters.
5. Lift and remove the plastic dividers from PCI-X slots 5 and 6 by lifting the ends
of the dividers out of the adapter support bracket and tilting the dividers up out
of the server.
6. Disconnect internal cables as necessary, remove the air-baffle assembly, and
remove the adapter-support bracket from the server. For complete details, see
"Removing and installing the adapter-support bracket" on page 19.
Note: You must remove the air-baffle assembly whenever you remove the
adapter-support bracket.
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 4 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 is installed, 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 marketing
representative or authorized reseller.
8. Reinstall the adapter-support bracket in the server (see "Removing and
installing the adapter-support bracket" on page 19).
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.
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 23 or "Installing a
non-hot-plug adapter (any slot)" on page 26 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
