Features The NiMH batteries in the battery module are continuously recharged through a trickle charging process whenever the system power is on. Under normal operating conditions, the battery module lasts for three years before replacement is necessary. IMPORTANT: The battery module may have a low charge when it is first installed. In this case, a Power-On Self-Test (POST) message 1794 is displayed when the server is powered up (see Appendix F), indicating that the array accelerator is temporarily disabled. No action is required on your part, since the internal circuitry automatically recharges the batteries. The recharge process can take up to four hours. The array controller will function properly during this time, although without the performance advantage of the array accelerator. When the batteries are charged to 79 percent of their capacity, the array accelerator is automatically enabled. The battery module can be removed from the server without using any tools. For detailed instructions, refer to the documentation that ships with your server and with the option kit. CAUTION: When using the battery module, observe the following limitations: • Do not transfer the battery module between different server models. • Do not add or remove the battery module while array capacity expansion, RAID level migration, or stripe size migration is in progress. The battery module has two LEDs, one green and one amber. When the battery module is connected to the controller and the server is powered up, the green LED indicates the status of the battery charge. When the battery is connected to the controller and the server is powered down, the amber LED indicates the status of data retention. See Table 1-1 for an interpretation of the possible LED illumination patterns. CAUTION: After the server is powered down, wait 15 seconds and then check the illumination pattern of the LEDs before unplugging the cable from the battery module. • If the amber LED blinks after 15 seconds, do not remove the cable from the battery module. The module is backing up data, and data will be lost if the cable is detached. • If neither LED blinks after 15 seconds, it is safe to remove the cable from the battery module. When the server is on, review the POST message before plugging or unplugging the cable from the battery module. Compaq Smart Array 5i Plus Controller User Guide 1-3

The NiMH batteries in the battery module are continuously recharged through a
trickle charging process whenever the system power is on. Under normal operating
conditions, the battery module lasts for three years before replacement is necessary.
IMPORTANT:
The battery module may have a low charge when it is first installed. In this
case, a Power-On Self-Test (POST) message 1794 is displayed when the server is powered
up (see Appendix F), indicating that the array accelerator is temporarily disabled. No action is

recharge process can take up to four hours. The array controller will function properly during
this time, although without the performance advantage of the array accelerator. When the
batteries are charged to 79 percent of their capacity, the array accelerator is automatically

The battery module can be removed from the server without using any tools. For
detailed instructions, refer to the documentation that ships with your server and with
the option kit.
CAUTION:
When using the battery module, observe the following limitations:
•
Do not transfer the battery module between different server models.
•
Do not add or remove the battery module while array capacity expansion, RAID
level migration, or stripe size migration is in progress.
The battery module has two LEDs, one green and one amber. When the battery
module is connected to the controller and the server is powered up, the green LED
indicates the status of the battery charge. When the battery is connected to the
controller and the server is powered down, the amber LED indicates the status of data
retention. See Table 1-1 for an interpretation of the possible LED illumination
patterns.
CAUTION:
After the server is powered down, wait 15 seconds and then check the
illumination pattern of the LEDs before unplugging the cable from the battery module.
•
If the amber LED blinks after 15 seconds, do not remove the cable from the
battery module. The module is backing up data, and data will be lost if the cable
is detached.
•
If neither LED blinks after 15 seconds, it is safe to remove the cable from the
battery module.
When the server is on, review the POST message before plugging or unplugging the
cable from the battery module.
