Safety: Before You Remove the Access Panel
Before removing the access panel for any reason, observe these safety guidelines.
Turn off all peripheral devices connected to the server.
Turn off the server by pressing the power button on the front of the chassis. Then unplug
the AC power cord on the back of the chassis.
Disconnect all peripheral cables and all telecommunication lines connected to the I/O
connectors or ports on the back of the chassis.
Warning: The power button on the front panel DOES NOT turn off the AC
power. To disconnect power from the server, you must unplug the AC power
cord from the wall outlet or the chassis.
Warning: Hazardous electrical conditions may be present on power,
telephone, and communication cables. Turn off the server and disconnect
the power cords, telecommunications systems, networks, and modems
attached to the server before opening the server case. Otherwise, personal
injury or equipment damage can result.
Warning: Hazardous voltage, current, and energy levels are present inside
the power supply. There are no user-serviceable parts inside the power
supply; servicing should be performed by technically qualified personnel.
Caution: For proper cooling and airflow, always install the access panel
before turning the server on. Operating the server without the access panel
in place can damage system parts.
