Removing and replacing the time-of-day battery in the 9006-12P system

Learn how to remove and replace the time-of-day battery in the IBM® Power® System LC921 (9006-12P) system.

1. Attach the electrostatic discharge (ESD) wrist strap.
   The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is completed, and if applicable, until the service access cover is replaced.

   Attention:

   • Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging your hardware.
   • When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is used for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds. If at any point in this service process you move away from the system, it is important to again discharge yourself by touching an unpainted metal surface for at least 5 seconds before you continue with the service process.
2. If the time-of-day battery is covered by a PCIe adapter, move the PCIe adapter out of the way.
   For instructions, see Removing a PCIe adapter from the 9006-12P system.
3. Remove the time-of-day battery (A) by pushing the tab (B) away from the battery as shown in Figure 1.
   When you remove the battery, do not use a metallic tool to disengage it from its slot.

   

4. Replace the time-of-day battery (A).
   The orientation of the + of the battery is up as shown in the following figure.

   

5. If you moved a PCIe adapter to access the battery, replace the PCIe adapter.
