Replacing the 2145 UPS-1U battery

Follow all safety notices when you are replacing the 2145 UPS-1U battery.

CAUTION:

Lead-acid batteries can present a risk of electrical burn from high, short-circuit current. Avoid battery contact with metal materials; remove watches, rings, or other metal objects, and use tools with insulated handles. To avoid possible explosion, do not burn.

Exchange only with the IBM-approved part. Recycle or discard the battery as instructed by local regulations. In the United States, IBM has a process for the collection of this battery. For information, call 1-800-426-4333. Have the IBM part number for the battery unit available when you call. (C004)

Use the reference numbers in parentheses at the end of each notice, such as (C003) for example, to find the matching translated notice in IBM® Systems Safety Notices.

This task assumes that you have disconnected the 2145 UPS-1U battery and have turned off the SAN Volume Controller. Perform the following steps to replace the 2145 UPS-1U battery:

Slide the battery into the 2145 UPS-1U, as shown in Figure 1.

Thread the battery connector through the battery cover. Position the battery cover in place and slide it to the left to secure it.
Connect the internal battery connector, as shown in Figure 3. Each end of the keyed connector has two wires: one red (+) and one black (−). Join the black wires and the red wires together.
Note: A small amount of arcing might occur when connecting the batteries. This is normal and does not damage the unit or present any safety concerns.

Push the front panel to the right to catch on the left end of the panel. Push the front panel forward until the panel snaps into the right and middle sections of the 2145 UPS-1U, as shown in Figure 3.

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: 2145 UPS-1U to resolve the problem.
Note: Ignore all error indicators until the self-test has been run.
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.
