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.
The illustrations in this document might differ slightly from your hardware.
Removing the top cover
Attention: For proper cooling and airflow, replace the top cover before you turn
on the server. Operating the server for more than 2 minutes with the top cover
removed might damage server components.
To remove the top cover, complete the following steps:
1. Read the safety information that begins on page vii and “Installation guidelines”
on page 37.
2. If you are installing or replacing a non-hot-swap component, turn off the server
and all attached peripheral devices. Disconnect all power cords; then,
disconnect all external signal cables from the server.
3. Slide the server out of the rack until the slide rails lock into place.

and use any packaging materials for shipping that are supplied to you.
