Before you remove server covers
Before removing covers at any time to work inside the system, observe these safety
guidelines.
1. Turn off all peripheral devices connected to the system.
2. Power down the system:
a. If the server is running an operating system, use its commands or GUI to
logoff (if necessary) and exit the operating system. Successfully exiting the
operating system causes the following prompt to appear:
Shell>
b. After this prompt appears, press and hold the Power button for several
seconds. Holding the Power button in powers down the server.
Note: Powering down the server with the Power button does not remove all
power from the system. The +12 Volt standby power is still available to
the system even when it has been powered down. To remove standby
power from the system you must unplug both power cables from the
chassis.
3. After the server shuts down, unplug both AC power cords to remove standby
power from the server.
4. Label and disconnect all peripheral cables and all telecommunication lines
connected to I/O connectors or ports on the back of the system.

• Connector, wall outlet end: Cords must be terminated in grounding-
type male plug designed for use in your region. It must have
certification marks showing certification by an agency acceptable in

receptacle on the server must be an IEC 320, sheet C19, type female
