Upgrades 5-15
Replacing the Cover When you have finished the upgrade or servicing, always replace the
server’s cover before plugging it in.
WARNING: To avoid a fire hazard, always replace the cover. Powering
on the server without a cover can cause it to overheat. The warranty is
void if this occurs.
To replace the cover, do the following:
1 Place the cover on the server enclosure.
To ensure correct placement, make sure that the panel with the greater
number of ventilation holes is positioned on the left side (viewed from
the front of the server).
2 If you are remounting the server in a rack, replace the rack-mounting
brackets on the sides of the server.
3 Using a Phillips screwdriver, tighten the black screws in the corners of
the cover until snug. Do not overtighten.
4 If you installed rack-mounting brackets in step 2, remount the server in
the rack.
Refer to Figure 2-1 on page 2-3 to see how the server is mounted in a
rack.
5 Recable any connectors whose cables have been removed.
6 Make sure the AC power switch is in the O or off position.
7 Attach the power cord to the receptacle on the back panel.
8 Plug the other end of the power cable into an AC power source.
9 Power on the server.
