5. Ensure that the 2145 UPS-1U is turned on. Press and hold the 2145 UPS-1U test button for three
seconds to start the self-test. If any of the Alarm, Battery, or Overload indicators are on or the buzzer
is sounding, go to MAP 5150 in the IBM System Storage SAN Volume Controller Troubleshooting Guide to
resolve the problem.
Note: Ignore all error indicators until the self-test has been run.
6. Turn on the SAN Volume Controller.
Note: If the new battery does not have enough charge to support the actions that are required during
a power failure, the SAN Volume Controller node pauses with Charging displayed on its front panel
until a sufficient charge is available. If there is a sufficient charge to support the actions that are
required during a single power failure but not sufficient charge to support two power failures, the
node starts and joins the cluster but displays Recovering on its front panel.
