Removing and replacing the node canister battery

Edit online

To remove and replace a faulty battery with a new one received from stock, use this procedure.

About this task

No tools are required to complete this task. Do not remove or loosen any screws.

CAUTION:
The battery is a lithium ion battery. To avoid possible explosions, do not burn. Exchange only with the approved part. Recycle or discard the battery as instructed by local regulations. (C007a)

Procedure

  1. Refer to the Event Log to identify the enclosure and node canister where battery replacement is required. Alternately, follow the procedure Procedure: Understanding the system status from the LEDs.
  2. Label each network and power cable connection or otherwise record all cables that are connected to the node canister. This information is used to reconnect the node canister later.
  3. Disconnect all cabling from the back of the node canister.
  4. Remove the node canister, as described in Reseating a node canister in the control enclosure.
  5. Remove the cover, as described in Removing and replacing the cover of a node canister.

Removing the battery

  1. Lift the node battery latch up, as shown in Figure 1.

  2. Slide the node battery toward the latch until it stops, as shown in Figure 2.

Replacing the battery

  1. Open the battery latch.
  2. Place the replacement battery into the battery slot so the pins on the board engage with the slots on the underside of the battery.
    Figure 4 shows the battery slots.

  3. Connect the battery by carefully sliding it towards the battery connector.
    Note: When you insert the new battery, be careful not to damage the connector cable for fan 5. As Figure 5 shows, the fan 5 connector passes through the partition of the battery compartment.

  4. Rotate the node battery latch down so that it holds the battery in place.
  5. Replace the node canister cover, as described in Removing and replacing the cover of a node canister.
  6. Reinsert the node canister, as described in Reseating a node canister in the control enclosure.
  7. Reconnect the cables to the node canister, ensuring that each cable goes into the same port and power supply unit (PSU) from which it was removed.
    If the node canister does not begin to power up, check that the canister is fully inserted into the enclosure.
  8. When the node canister is back online, check the Event Log for any new events that might indicate a problem with the reassembly.
    Note: A new node error or event ID in the Event Log might indicate that the new battery is functioning but requires some time to reach minimum charge. Monitor the Event Log until the battery is charged sufficiently for the node to boot.
