To remove the server top cover:
1. If you are planning to install or remove any part other than a hot-swap hard
disk drive, hot-plug adapter, hot-swap power supply, or hot-swap fan, turn off
the server and all attached devices and disconnect all external cables and
power cords (see “Preparing to install options” on page 46).
2. Release the left and right side latches

and pull the server out of the rack
enclosure until both slide rails lock.
Note: When the server is in the locked position, you can easily reach the
cables on the back of the server.
3. Move the cover-release lever

down while sliding the top cover

toward
the rear of the server about 25 mm (1 inch). Lift the cover off the server and
set the cover aside.
Attention: For proper cooling and airflow, replace the cover before turning on
the server. Operating the server for extended periods of time (over 30 minutes)
with the cover removed might damage server components.
