CAUTION: After the server is powered down, wait 15 seconds and then check the amber LED
before unplugging the cable from the cache module. If the amber LED blinks after 15
seconds, do not remove the cable from the cache module. The cache module is backing up
data, and data is lost if the cable is detached.
IMPORTANT:
error message is displayed when the server is powered up, indicating that the battery pack is
temporarily disabled. No action is necessary on your part. The internal circuitry automatically
recharges the batteries and enables the battery pack. This process might take up to four
hours. During this time, the cache module functions properly, but without the performance
advantage of the battery pack.
NOTE: The data protection and the time limit also apply if a power outage occurs. When
power is restored to the system, an initialization process writes the preserved data to the hard
drives.
