Removing the power cable

Complete this task to remove the power cord from an enclosure.

CAUTION:
The power-control button on the device does not turn off the electrical current supplied to the device. The device might also have more than one connection to dc power. To remove all electrical current from the device, ensure that all connections to dc power are disconnected at the dc power input terminals.
ESD warningUse approved ESD procedures to prevent damage.

The error indicator must be lit on the power supply before you can safely remove the power cable.

Removing and replacing an ac power cable might result in the following effects:
  • If you disconnect the ac power cable, it can cause a fault to be reported by the power supply.
  • If the second power supply fails while the first power supply is not receiving power, the enclosure loses power and you can lose access to all data.

The power supplies are located on the left and right sides of the rear of the enclosure.

  1. Pull the power cord from the power outlet on the wall.
