AC Power Supply

The device provides two hot-swappable Power Supply modules for load-sharing and power redundancy in case of failure in one of the modules. To replace a faulty power supply module, see Replacing the Fan Tray Module.

The device receives power from a standard alternating current (AC) electrical outlet. The connection is made using the supplied AC power cord.

To connect the device to power:

1.

Swing the cable anchor clip, located over the power inlet of the Power Supply module, sideways, away from the power inlet to provide space for the power plug.

2.

Plug the female end of the AC power cord (supplied) into the power inlet.

3.

Secure the power cord to the power inlet by providing strain relief, using the cable anchor clip. Slide the cable anchor clip sideways, towards the power inlet and then push the power cord into the cable anchor clip, as shown in the following figure. This protects the plug from accidentally being pulled out.

4.

Connect the male end of the power cord to a standard AC electrical outlet.

5.

If you are using both Power Supply modules, repeat steps 1 through 3 for connecting the second Power Supply module, but using the power socket associated with the second Power Supply module and connecting this to a different supply circuit.

6.

Turn on the power at the power source (if required).

7.

Check that the LED on each Power Supply module (front panel) is lit green, indicating that the device is receiving power. For more information on the power LED, see Power Supply LED.
