3. Remove the top cover by following the procedure described in the "Opening and closing the server"
section on page 12.

IMPORTANT: To streamline the configuration process, read through the entire installation and removal
procedures first and make sure you understand them before you before you begin.

Post-installation procedures

Perform the steps below 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 boards, riser board assemblies, peripherals, board covers, brackets, and system
cables that you have removed.
4. Reinstall the top cover by following the procedure described in the "Opening and closing the server"
section on page 12.
5. Connect all external cables and the AC power cord to the system.
Route the cables properly through the available cable management arrangement.
6. Press the power button on the front panel to turn on the server.

Powering down the server

The server does not completely power down when the power button is pressed. The power button toggles
between On and Standby. The standby position removes power from most electronics and the drives, but some
internal circuitry remains active. To completely remove all power from the system, disconnect all power cords
from the server.
To power down the server:
1. Shut down server as directed by the operating system documentation.
2. Press the power button to toggle to Standby.
This places the server in standby mode and changes the power LED indicator to amber. In this mode, the
main power supply output is disabled. Standby does not completely disable or remove power from the
system.
3. Disconnect the AC power cord from the AC outlet and then from the server.
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.

Opening and closing the server

The top cover is detachable. You need to remove this cover before you can remove or replace a server
component.
To open the server:
1. Perform steps 1 and 2 of the pre-installation procedures on page 11.
2. Detach the top cover from the chassis:
a. Loosen the captive screw on the rear panel.
To loosen the screw, HP recommends using the L-shaped wrench that ships with the server.
b. Slide the cover approximately 1.25 cm (0.5 in) toward the rear of the unit, then lift the cover away
from the chassis.
You can use the two circular grips on the top cover to help you slide the cover more easily.
