Removing the power cable from the 2145 UPS

You can replace the power cable from the 2145 UPS if you are having problems with the power supply and suspect that the power cable is defective.

1. Remove the power from each SAN Volume Controller node. See MAP 5350: Powering off a SAN Volume Controller node for information about removing the power cable from the SAN Volume Controller.
2. Press and hold the off switch . A long beep sounds for approximately five seconds. When the beep stops, release the switch. The mode indicator , shown in Figure 1, flashes and the 2145 UPS enters standby mode.
