3. If you are planning to install or remove a microprocessor, memory module, PCI
adapter, battery, or other non-hot-swap optional device, turn off the server and
all attached devices and disconnect all external cables and power cords (see
"Turning off the server" on page 22).
4. Press down on the left and right side latches and slide the server out of the rack
enclosure until both slide rails lock.
Note: You can reach the cables on the rear of the server when the server is in
the locked position.
5. Press the blue latch 1 on the end of the cover-release latch and lift the
cover-release latch 2 . Slide the cover toward the rear 3 and lift the cover off
the server. Set the cover aside.
Attention: For proper cooling and airflow and to avoid damaging server
components, replace the cover before you turn on the server. If you operate the
server for extended periods of time (over 30 minutes) with the cover removed, the
IMM turns off the server.
