11 Servicing the Battery (CRU)

This section describes how to service the system battery. The system battery is a customer-replaceable unit (CRU) that requires you to power off the server. For more information about CRUs, see Illustrated Parts Breakdown and Customer-Replaceable Units.

The real-time clock (RTC) battery maintains system time when the server is powered off and a time server is unavailable. If the server fails to maintain the proper time when the system is powered off and not connected to a network, replace the battery.

Caution:

These procedures require that you handle components that are sensitive to electrostatic discharge. This sensitivity can cause the components to fail. To avoid damage, ensure that you follow antistatic practices as described in Electrostatic Discharge Safety.

Caution:

Ensure that all power is removed from the server before removing or installing the battery. You must disconnect the power cables from the system before performing this procedure.

This section covers the following procedures:

Extend the Server to the Maintenance Position
Remove the Server Top Cover

Remove the Battery

  1. Prepare the server for service.
    1. Power off the server and disconnect the power cords from the server power supplies.
    2. Extend the server into the maintenance position.
    3. Attach an antistatic wrist strap to your wrist, and then to a metal area on the chassis.
    4. Remove the server top cover.
  2. To dislodge the battery from its retainer, use your finger to gently push the top edge of the battery away from the retainer.

    Note:

    To gain access to the battery, you might need to disconnect and move aside the auxiliary signal cable to the disk backplane and the SAS cables to the Internal HBA. For more information, see Servicing the Disk Backplane (FRU) and Servicing SAS Cables (FRU).

    Figure showing how to remove the system battery.
  3. Lift the battery up and out of its retainer.

Install the Battery

  1. Unpack the replacement battery.
  2. Press the new battery into the battery retainer.

    Note:

    If disconnected during battery removal, reconnect the auxiliary signal cable to the disk backplane and the SAS cables to the Internal HBA. For more information, see Servicing the Disk Backplane (FRU) and Servicing SAS Cables (FRU).
  3. Return the server to operation.
    1. Install the server top cover.
    2. Return the server to the normal rack position.
    3. Reconnect the power cords to the server power supplies, and power on the server.
    4. Verify that the System OK LED indicator is lit.

      Note:

      If the service processor is configured to synchronize with a network time server using the Network Time Protocol (NTP), the Oracle ILOM SP clock is reset as soon as the server is powered on and connected to the network. Otherwise, proceed to the next step.
  4. If the service processor is not configured to use NTP, you must do one of the following:
