Removing the power cable from the 2145 UPS-1U

You can remove the power cable from the 2145 UPS-1U 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 on/off button  until the power light  is extinguished (approximately five seconds). On some versions of the 2145 UPS-1U, you need a pointed device, such as a screwdriver, to press the on/off button. The 2145 UPS-1U enters standby mode, with all indicators off. Figure 1 illustrates the front and rear views of the 2145 UPS-1U.

3. Disconnect the power cable from the main power source .
4. Replace the power cable and make sure it is seated. The 2145 UPS-1U enters standby mode. All indicators are off and power is not available to the SAN Volume Controller. The battery recharges when necessary.
5. To turn the 2145 UPS-1U on, press and hold the on/off button  until the 2145 UPS-1U power button  is illuminated (approximately five seconds). On some versions of the 2145 UPS-1U, you need a pointed device, such as a screwdriver, to press the on/off button. The front panel indicators then cycle through a startup sequence while the 2145 UPS-1U conducts a self-test. When the self-test completes, the power-on indicator and the load indicators illuminate to show that the 2145 UPS-1U is supplying power. The 2145 UPS-1U resumes service in normal mode.
