3.

4.
Be sure that the power LED indicator is turned off and that the fan noise has stopped.
5.
Disconnect all external peripheral devices from the server.
WARNING:
To completely remove all power from the system, disconnect all power cords from the
server.
WARNING:
Hazardous voltages are present inside the server. Always disconnect AC power from
the server and other associated assemblies while working inside the unit. Serious injury may result if
this warning is not observed.
WARNING:
To reduce the risk of injury from electric shock, disconnect all power cords to
completely remove power from the system.
WARNING:
To reduce the risk of personal injury from hot surfaces, allow the internal system
components to cool before touching them.
CAUTION:
Protect the server from power fluctuations and temporary interruptions with a regulating
uninterruptible power supply (UPS). This device protects the hardware from damage caused by
power surges and voltage spikes, and keeps the system in operation during a power failure.
CAUTION:
The server must always be operated with the system covers on. Proper cooling is not
achieved when the system covers are removed.
System covers
The access panel and the front bezel are both detachable. Both system covers must be removed and
detached before removing or replacing non-hot-plug components. Servers configured with hot-plug
drives require only the front bezel to be removed to remove and replace hot-plug drives.
Access panel
To remove the access panel:
1.
If necessary, unlock the unit using the supplied key.
2.
Loosen the captive thumbscrews located on the rear edge of the access panel.
3.
Slide the panel back about 1.3 cm (0.5 in).
NOTE:
The access panel does not need to be removed for removal and replacement of hot-plug
drives.
