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.

voltages.
4. Open the server according to the instructions described in the “System Covers” section
on the bottom of this page.

Post-installation Instructions
Observe the following items after installing or removing a server component:
1. Be sure all components are installed according to the described step-by-step instructions.
2. Check to make sure you have not left loose tools or parts inside the server.
3. Reinstall any expansion board(s), peripheral(s), board cover(s), and system cable(s) that
have previously been removed.
4. Reinstall the system covers.
5. Connect all external cables and the AC power cord to the system.
6. Turn on the server.
CAUTION:
Do not operate the server for more than ten (10) minutes with the left-side cover
and disk drives removed. Otherwise, improper cooling airflow may damage the system
components.
System Covers
The server’s left-side cover and the front bezel are both detachable. You need to remove
these system covers before you can change the hardware configuration.
WARNING: In opening the server, be careful to avoid accessing the insides of the
power supply unit. The PSU has no serviceable parts. Return it to the manufacturer for
servicing.
