To install a SCSI repeater card:
Attention: When you handle static-sensitive devices, take precautions to avoid
damage from static electricity. For details on handling these devices, see “Handling
static-sensitive devices” on page 37.
1. Review the information in“Before you begin” on page 36 through “Safety
information statements” on page 38.
2. Turn off the server and peripheral devices, and disconnect all power cords and
external cables; then, remove the top cover (see “Removing the server top cover
and bezel” on page 40).
3. If a ServeRAID adapter is installed in the server, disconnect the SCSI cable from
the adapter (see “Cabling example for the ServeRAID adapter” on page 47).
4. Disconnect the shuttle:
a. Disengage the retaining levers by pressing inward.
b. Move the retaining levers back to the unlocked position.
c. Slide the shuttle toward the rear of the server until it stops.
Note: It is not necessary to remove the shuttle from the server.
5. Remove fan assembly 1 from the server (see “Replacing a hot-swap fan” on page
76).
6. Disconnect the hot-swap hard disk drives from the corresponding SCSI backplane
connectors; then, slide the drives forward.
