Removing and replacing consumable parts and Tier 1 CRUs
Replacement of consumable parts and Tier 1 CRUs is your responsibility. If IBM
installs a consumable part or Tier 1 CRU at your request, you will be charged for
the installation.
Note: The illustrations in this document might differ slightly from your hardware.
Removing the cover
To remove the server cover, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 167.
2. Turn off the server and peripheral devices and disconnect the power cords and
all external cables, if necessary.
Note: When you disconnect the power source from the server, you lose the
ability to view the LEDs because the LEDs are not lit when the power source is
removed. Before you disconnect the power source, make a note of which LEDs
are lit, including the LEDs that are lit on the operation information panel, on the
light path diagnostics panel, and LEDs inside the server on the system board;
then, see “Light path diagnostics LEDs” on page 104 for information on how to
solve the problem.

3. If the server has been installed in a rack, slide the server out from the rack
enclosure.
4. Press down firmly on the blue tab on the top (near the front of the server) of the
cover and slide the cover toward the rear of the server until the cover has
disengaged from the chassis.
5. Lift the server cover off the server and set it aside.
Attention: For proper cooling and airflow, replace the server cover before you
turn on the server.
Installing the cover
To install the server cover, complete the following steps:
1. Make sure that all cables, adapters, and other components are installed and
seated correctly and that you have not left loose tools or parts inside the server.
Also, make sure that all internal cables are correctly routed.
