Removing and replacing Tier 1 CRUs
Replacement of Tier 1 CRUs is your responsibility. If IBM installs a Tier 1 CRU at
your request, you will be charged for the installation.
The illustrations in this document might differ slightly from your hardware.
Removing the cover
To remove the cover, complete the following steps.
Cover release
thumb screws
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 43.
2. If you are planning to install or remove a microprocessor, memory module, PCI
adapter, fan-bracket assembly, 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 6).
3. Loosen the rack-release thumbscrews at the front of the server; then, pull the
server out of the rack enclosure until both slide rails lock.
Note: You can reach the cables on the back of the server when the server is in
the locked position.
4. Loosen the cover-release thumbscrews at the rear of the server. Lift the cover
off the server and set the cover aside.
Attention: For proper cooling and airflow, replace the cover before turning on
the server. Operating the server for extended periods of time (over 30 minutes)
with the cover removed might damage server components.
5. If you are instructed to return the cover, follow all packaging instructions, and
use any packaging materials for shipping that are supplied to you.
Installing the cover
To install the cover, place it into position and slide it forward; then, tighten the
cover-release thumbscrews.
