Battery

Use this procedure to service the battery.

1. Access the ASMI

   The Advanced System Management Interface (ASMI) is the interface to the service processor that is required to perform general and administrator-level service tasks, such as reading service processor error logs, reading vital product data, setting up the service processor, and controlling the system power. The ASMI may also be referred to as the service processor menus. To access the ASMI, refer to Accessing the Advanced System Management Interface. When you have accessed the ASMI, continue with the next step.

2. Check and record the server firmware and service processor settings

   Check and record the admin user ID's password. Check and record the server firmware level prior to replacing this FRU. You may need to update the system to the latest server firmware code level after you replace this FRU. Check and record the service processor settings you previously set using Advanced System Management (ASM). This can be done using a Hardware Management Console (HMC) or PC to access ASM. You will need to reset these service processor settings after you replace this FRU or the default settings will be used. Settings to record include the following: System Name setting System Power Control settings System Service Aids settings System configuration settings Network Services settings Performance Option settings Login Profile settings Boot List settings Host Ethernet Adapter settings Record any service processor settings you may have set using operating system commands.

3. Power off the unit

   Power should be removed from the unit containing the battery. If this unit is powered on, power it off now.

4. Disconnect the power cords

   Disconnect all power cords from the unit you are servicing.

1. Place into service position

   Note to expansion unit users: The instructions in this procedure are written based on the rack model. Expansion unit users can still use this procedure; however, expansion unit users should ignore specific references to rack-only features such as rack doors, rack thumbscrews, and rack-specific FRU orientation. Attention: When placing the model rack into the service position, it is essential that all stability plates are firmly in position to prevent the rack from toppling. Ensure that only one system unit is in the service position at a time. Remove two screws (A) securing the system unit (B) to the rack.

2. Place into service position (continued)

   While holding the system unit release latches (A) down on both the left and right sides, pull the system unit (B) out from the rack until the rails are fully extended and locked.
