HP Integrity rx2660 Server User Service Guide

Removing and Replacing the Top Cover
NOTE: When the top cover is open or removed while the server is running, the server fans
increase to high speed to assist cooling. When the top cover is replaced at the end of the operation,
the server fans return to normal speed.
15 minutes After 15 continuous minutes of having the chassis cover open, the BMC issues a
soft shutdown. It tells the operating system to gracefully shut the operating system
down. Once the operating system accomplishes this and communicates it to the
BMC, system power is turned off
30 minutes After 30 continuous minutes of having the chassis cover open, the BMC performs
a hard power-off of the system. This occurs because the operating system did not
respond to the BMC's earlier request to gracefully shut the operating system down.
Removing the Top Cover
To remove the top cover:
1. If rack mounted, fully extend the server out from the rack. See “Extending the Server from the
Rack” (page 141).
2. Using the Allen wrench, provided on the rear panel of the server, unlock the cover release
lever (if necessary) by turning the cam approximately 90 degrees counter-clockwise (1).
3. Pull up on the cover release lever to disengage the top cover from the server (2).
4. Slide the cover toward the rear of the server until the tabs release from the slots in the chassis
(3).
5. Lift the cover off the server (4).
