Note: If your server is a tower model, you might find it easier to install the
hot-swap power-supply option if you turn the server on its side so that the
power supply is on the bottom.
1. Review the information in “Installation guidelines” on page 45, “Handling
static-sensitive devices” on page 46, and “Safety information” on page 169.
2. Turn off the server and disconnect all power cords and external cables
(“Turning off the server” on page 9); then, remove the server cover (see
“Removing the server left-side cover and bezel (tower model)” on page 55 or
“Removing the server top cover and bezel (rack configuration)” on page 57).
3. Remove the adapter-support bracket. See “Removing and installing the
adapter-support bracket” on page 58 for instructions.
4. Disconnect the power-supply cables from the system board and devices in
your server.
a. Disconnect the small-device power cable (P7) from the back of the diskette
drive.
Note: You might need to remove the diskette drive from the server in order
to disconnect and reconnect its cables. The diskette drive is held in
the server by release tabs that are accessed by removing the server
front bezel.
b. Disconnect the device power connector (P5) from the back of the CD-ROM
drive.
c. Disconnect the other device power connectors (P4 and P6) from the rear of
any other devices in the server.
d. Disconnect the SCSI cable (P2) from the SCSI backplane.
e. Disconnect the power cable (P1) from the J4 connector on the system
board.
f. Disconnect the power signal cable (P3) from the J10 connector on the
system board.
g. If your server has the 3-Pack Ultra320 Hot-Swap Expansion option
installed, disconnect the power connector (P8) from the power connector
on the 3-Pack backplane.
5. Remove the fixed power supply (see the following illustration).
