SPARC T8-4 Server Service Manual

Replace the Battery

1. Prepare the host for battery replacement.

   To correctly reset the date and time before replacing a battery, you must revent the host from automatically powering on and disable any NTP connections.

   1. Check the HOST_AUTO_POWER_ON property.

      -> show /SP/policy HOST_AUTO_POWER_ON
        Properties:
           HOST_AUTO_POWER_ON = enabled

   2. If enabled, set the HOST_AUTO_POWER_ON property to disabled.

      -> set /SP/policy HOST_AUTO_POWER_ON=disabled

   3. Check the NTP policy for the /SP/clock.

      -> show /SP/clock usentpserver
         Properties:
            usentpserver = enabled

   4. If enabled, set the property to disabled.

      -> set /SP/clock usentpserver=disabled

2. Replace the battery.

   Replacing the battery is a cold-service procedure. The server must be completely powered off and power cables disconnected before performing this procedure.

   1. Prepare the server for service.
   2. Remove the main module from the server.

      See Remove the Main Module.

   3. Locate the battery in the main module.

      See Main Module Components.

   4. Remove the old battery.

      Gently push the battery toward the side of the server to release it from the retention clip.

      
      
   5. Unpack and install the new battery.

      Press the new battery into the battery holder with the positive side (+) facing away from the metal tab that holds it in place.

      
      
   6. Install the main module back into the server.

      See Install the Main Module.

   7. Return the Server to Operation.
3. Reset the system clock.
   1. Use the Oracle ILOM clock command to reset the system clock.

      The following example sets the date to August 22, 2016, and the timezone to EDT.

      -> set /SP/clock datetime=081221302016 timezone=EDT
      Set 'datetime' to '081221302016'
      set 'timezone' to 'EDT'
      
      -> show -d properties /SP/clock
       Properties
          datetime = Mon Aug 22 13:20:16 2016
          timezone = EDT (EST5EDT)
          uptime = 2 days 19:56:49
          usentpserver = disabled

   2. If the SP policy HOST_AUTO_POWER_ON was enabled before you replaced the battery, you must re-enable it.

      -> set /SP/policy HOST_AUTO_POWER_ON=enabled

   3. If the /SP/clock usentpserver property was enabled before you replaced the battery, you must re-enable it.

      -> set /SP/clock usentpserver=enabled

4. Verify the battery.
