Preparing the 9009-41A, 9009-41G, 9009-42A, 9009-42G, 9223-42H, or 9223-42S system for operation after removing and replacing the time-of-day battery

To prepare the system for operation after removing and replacing the time-of-day battery, complete the steps in this procedure.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Replace the service access cover.
   For a rack-mounted system, complete the following steps. Refer to Figure 1.

   1. Slide the cover (A) onto the system unit.
   2. Close the release latch (B) by pushing it in the direction shown.

   

   For a stand-alone system, complete the following steps. Refer to Figure 2.

   1. Slide the cover (B) on to the system unit as shown.
   2. Close the latch release (A) by pushing it in the direction shown.

   

3. For a rack-mounted system, unlock the blue rail safety latches (A) as shown in Figure 3 by pushing them inward.
   Ensure that the cable management arms can move freely. Ensure that the cables at the rear of the unit do not catch or bind as you push the unit into the operating position.

   

4. For a rack-mounted system, push the system unit (B) as shown in the previous figure back into the rack until both release latches lock the system into position.
   Secure the cable management arm with hook-and-loop fasteners around the back side of the cable management arm, but not around the cables.
5. Using your labels, reconnect the power cords (A) to the system unit.
   Fasten the power cords (A) to the system using the hook-and-loop fasteners (B) as shown in Figure 4 or Figure 5.

   

   

6. Turn off the identify LED. For instructions, see Deactivating an identify LED.
7. Access the Advanced System Management Interface (ASMI).
   • You can access the ASMI without using the HMC. For instructions, see Accessing the ASMI without an HMC.

     • For HMC Version 10.1.1020.0, or earlier, click Resources > All Systems and select the system being serviced. Then, click Actions > View All Actions > Launch Advanced System Management (ASM).
     • For HMC Version 10.2.1030.0, or later, click System resources > Systems and select the system being serviced. Then, click Connections and operations > Launch Advanced System Management (ASM).
8. If the system is powered off, reset the time-of-day settings by using the ASMI. To set the time-of-day, complete the following steps:
   1. In the navigation area of the ASMI, click System Configuration > Time of Day.
   2. The content pane displays a form that shows the current date (month, day, and year) and time (hours, minutes, and seconds).
   3. Change the date, the time, or both, and then click Save Settings.
9. To verify whether the time is set correctly, complete the following steps:
   1. Exit from the ASMI.
   2. Label and disconnect the power source from the system by unplugging the power cords from the system.
   3. Using your labels, reconnect the power cords to the system unit.
      Fasten the power cords to the system using the hook-and-loop fasteners.
   4. Access the ASMI.
      • You can access the ASMI without using the HMC. For instructions, see Accessing the ASMI without an HMC .
      • To access the ASMI by using the HMC, complete the following steps:
        1. Select the system that you are working with.
        2. Click Tasks.
        3. Click Operations > Launch Advanced System Management (ASM).
