Safety Guidelines

BEFORE YOU REMOVE SERVER COVERS, OBSERVE THESE GUIDELINES:
1. Turn off all peripheral devices connected to the server.
2. Turn off DC power in the server by pressing the push-button on/off power switch on the front
panel of the server.
3. Disconnect AC power to the server by unplugging the alternating current (AC) power cord
from the AC inlet filter or wall outlet.
4. Label and disconnect all peripheral cables attached to the I/O panel on the back of the server.
5. Provide some electrostatic discharge (ESD) protection by wearing an antistatic wrist strap
attached to chassis ground of the server—any unpainted metal surface—when handling
components.
Warnings and Cautions
These warnings and cautions apply whenever you remove the top and side covers of the server to
access components inside it. Integration of the server should be done only by technically qualified
personnel.

Server Precautions

WARNING
Server power on/off: The push-button on/off power switch on the front
panel of the server does not turn off the AC power. To remove AC
power from the server, you must unplug the AC power cord from the
AC inlet filter.
Hazardous conditions, power supply and power distribution backplane:
Hazardous voltage, current, and energy levels are present inside the
power supply and the power distribution backplane. There are no user-
serviceable parts inside them; servicing should be done only by
technically qualified personnel.
Hazardous conditions, devices and cables: Hazardous electrical
conditions may be present on power, telephone, and communication
cables. Turn off the server and disconnect telecommunications systems,
networks, modems, and each power cord attached to the server before
opening it. Otherwise, personal injury or equipment damage can result.
Avoid injury: The minimum server configuration weighs 51.4 kg
(113 lbs), and the maximum one weighs 60 kg (132 lbs). To avoid injury,
we recommend that a lift be used to insert the server into the slide
assemblies in the equipment rack.
