Installing Hardware Options

Preparing the Server

WARNING: To reduce the risk of electrical shock or damage to the equipment,
only service parts of the server as instructed in the user documentation.
WARNING: Pressing the Power On/Standby button to power down the server
removes power from most areas of the server. This process may take
30 seconds. Portions of the power supply and some internal circuitry remain
active until the AC power cord is disconnected.
To remove power completely, disconnect the power cord. If the server has
multiple power supplies installed, it is necessary to remove all power cords in
order to remove all power from the system.
WARNING: When performing non-hot-plug operations, you must power down
the system. However, it may be possible to leave the server powered up when
performing other operations, such as hot-plug installations or troubleshooting.
Use the procedures in this chapter and in Chapter 2, "Planning the Server
Installation," to prepare the server for hardware option installations.

Unlocking and Opening the Front Bezel

Tower servers have a removable front bezel. To access the hard drive cage and
removable media area, first unlock and open the bezel door. You must also unlock
the bezel before removing the access panel. During normal operations, the bezel door
must remain closed.
Use the key provided with the server to open the bezel lock with a counterclockwise
turn as shown in Figure 3-10. Refer to the maintenance and service guide if you need
to replace the key or other hardware components, or refer to
