Setting up your system
Setup reminders
• Do not attempt to modify or use the supplied AC power cord if it is
not the exact type required. A product with more than one power
supply will have a separate AC power cord for each supply.
• The power button on the system does not turn off system AC
power. To remove AC power from the system, you must unplug
each AC power cord from the wall outlet or power supply. The
power cord(s) is considered the disconnect device to the main (AC)
power. The socket outlet that the system plugs into shall be
installed near the equipment and shall be easily accessible.

2 Turn off the system by pressing the power button.
3 Unplug all AC power cords from the system or from wall outlets.
4 Label and disconnect all cables connected to I/O connectors or
ports on the back of the system.
5 Provide some electrostatic discharge (ESD) protection by wearing
an antistatic wrist strap attached to chassis ground of the system—
any unpainted metal surface—when handling components.
6 Do not operate the system with the chassis panels removed.
After you have completed the six steps above, you can remove the
chassis panels. To do this:

padlock has been installed.
2 Remove and save all screws from the panels.
