Removing and replacing Tier 1 CRUs
Installation of Tier 1 CRUs is your responsibility. If IBM installs a Tier 1 CRU at your
request, you will be charged for the installation.
Removing the left-side cover
To remove the left-side cover complete the following steps:
1. Read the safety information that begins on page vii and “Handling
static-sensitive devices” on page 151.
2. If you are installing or replacing a non-hot-swap component, turn off the server
and all peripheral devices, and disconnect the power cords and all external
cables.
3. Unlock the left-side cover, using the key that comes with the server.
4. Pull the cover-release latch down while you rotate the top edge of the cover
away from the server; then, lift the cover off the server.
Attention: For proper cooling and airflow, replace the cover before you turn
on the server. Operating the server for more than 2 minutes with the cover
removed might damage server components.
