Removing and Replacing System Top Metal Cover and Bezels
To upgrade, remove, or replace most server components, you must first remove the top metal
cover from the server chassis.
WARNING! Do not remove the server covers without powering off the server and unplugging
the power cord from the outlet or power protection device unless you are only replacing a
hot-swappable fan.
When the server is running, you must replace the top metal cover within 30 minutes to prevent
components from overheating. If the top metal cover is not replaced within 30 minutes, the server
automatically shuts down. If the server shuts off, always replace the cover before turning the
server back on.
Rack-Mount System
This section explains how to remove and replace the cover for the rack-mount configuration.
To access the internal components on a rack-mounted server, pull the server out on the rail guides
and remove the top metal cover.
Accessing a Rack Mounted Server
The server is designed to be rack mounted. The following procedure explains how to gain access
to a server that is mounted in an approved rack. For rack installation instructions, review the
HP Integrity rx2620 Server Rack Installation Guide.
WARNING! Ensure that all anti-tip features (front and rear anti-tip feet installed; adequate
ballast properly placed, and so on) are employed before you extend the server.
Extending the Server from the Rack
NOTE: Ensure that there is enough area (approximately 1.5 meters (4.5 ft.)) to fully extend the
server and work on it.
To extend the server from the rack:
1. Power off the server and disconnect the power cable and all other cables from the back of
the server. See
“Powering Off the Server” (page 37) .
2. Release the rack latches by rotating them outward. See Figure 4-3 .
