IBM eServer xSeries 255 Option Installation Manual page 57

v If you installed a SCSI device, install a SCSI signal cable by attaching one
end of the cable to the rear of the SCSI device that you installed. Attach the
other end of the cable to the internal SCSI connector (J15) on the system
board.
Important: At this time, you must connect a RAID or SCSI adapter to the
hard disk drives in the upper drive cage (see "Cabling a RAID or SCSI
adapter" on page 22 for additional information).
17. Connect a power cable to the rear of the drive. A three-drop power cable for
removable-media drives comes installed in your server. It is attached to the
standard CD-ROM drive. The connectors are keyed and can be inserted only
one way.
18. Reconnect the remaining internal cables (if any), except for the IDE signal
cable, diskette-drive signal cable, front-fan signal cable, and the cable that you
disconnected from the internal SCSI connector (J15) on the system board.
19. Slide the shuttle assembly back into place and secure it by locking the
metal-hinge latch.
20. Route the standard SCSI signal cable from the standard SCSI backplane
through the opening in the adapter-support bracket to the RAID or SCSI
adapter. Connect the unattached end of the cable to an internal channel
connector on the adapter (see "Cabling a RAID or SCSI adapter" on page 22).

21. Reconnect the internal IDE signal cable to the IDE system-board connector.
Reconnect the diskette-drive signal cable and front-fan signal cable to the
corresponding system-board connectors. See "System-board internal cable
connectors" on page 5 for cable locations.
22. Close the microprocessor airflow guide located between the front fans and the
microprocessors. Insert the tabs into the corresponding slots.
23. Reinstall the air baffle:
a. Align and insert the two tabs on the rear of the air baffle into the
corresponding slots on the rear of the server.
b. Align the hole on the front of the air baffle over the corresponding
alignment pin on the chassis; then, lower the air baffle into place.
Note: The alignment pin is located near the plastic fastener behind fan 1.
c. Press firmly on the two plastic fasteners until they snap into place on the
front of the air baffle. This secures the air baffle in the server.
