WARNING: There is a risk of explosion, fire, or personal injury if the battery pack is not properly handled. Refer to "Battery replacement notice (on page 93)" before installing or removing any item that contains a battery pack.
CAUTION: Do not replace a battery pack while the server is powered up. In this situation, the loose end of the battery cable that is still connected to the cache can cause a short circuit, leading to permanent electrical damage.
1.Close all applications, and then power down the server.
2.Disconnect the server from the AC power source.
3.Remove all components that prevent access to the battery pack. For more information, see the
4.Observe the BBWC Status LED ("Battery pack LEDs" on page 28):
o If the LED is flashing every two seconds, data is still trapped in the cache. Restore system power, and then repeat the previous steps in this procedure.
o If the LED is not lit, proceed with the next step.
5.Disconnect the cache cable from the battery pack.
6.Remove the battery pack from the server.
7.Connect the cache cable to the new battery pack.
8.Install the new battery pack into the server.
NOTE: After installing a battery pack, you might see a POST message during reboot indicating that the array accelerator (cache) is temporarily disabled. This is normal, because the new battery pack is likely to have a low charge. You do not need to take any action, because the recharge process begins automatically when the battery pack is installed. The controller will operate properly while the battery pack recharges, although the performance advantage of the array accelerator will be absent. When the battery pack has been charged to a satisfactory level, the array accelerator will automatically be enabled.
Replacing the E500 or P400 cache
CAUTION: The cache module connector does not use the
1.Close all applications, and then power down the server. This procedure flushes all data from the cache.
2.Disconnect the power cord from the AC power source.
3.Disconnect the power cord from the server.
4.If the existing cache is connected to a battery, observe the BBWC Status LED ("Battery pack LEDs" on page 28).
o If the LED is flashing every 2 seconds, data is still trapped in the cache. Restore system power, and then repeat the previous steps in this procedure.
