CAUTION: For proper cooling, do not operate the server without the access panel, baffles, expansion slot covers, or blanks installed. If the server supports hot-plug components, minimize the amount of time the access panel is open.

1. Power down the server on page 18

2. Remove all power:

a. Disconnect each power cord from the power source. b. Disconnect each power cord from the server.

3. Extend (Extend the server from the rack on page 19) or remove the server from the rack.

IMPORTANT: It is necessary to remove the PCI riser cage only if there is a full-length expansion board installed.

5. Release the full-length expansion board retainer, and then remove the PCI riser cage.
