Replacing the Battery Unit
Detecting a Failed Battery Unit
To determine whether the battery unit needs to be replaced, check the following:
•
Ensure that the component to be replaced has a status of Critical or Non-Operational:
–
In the Physical View in ICON Manager, select the battery to see it status, or
–
From the ISE’s CLI, type
show battery
•
Logs in ICON Manager
•
On the failed battery unit, the amber LED is on and green LED is off, indicating that the
component is ready to be removed
Removing an Operational Battery
Typically, only a failed battery unit (one with its amber LED on) should be removed. If you are
removing an operational battery (one with its green LED on), note the following:
Note:
In the event of a power supply failure, batteries operate together to
provide power to cache. Before beginning battery replacement, make
sure the other battery is operational. If both batteries are bad, call
Xiotech Customer Support. If the Emprise 7000 system does not have
an operational battery, the system will shut down.
Note:
At times during calibration, the battery’s capacity falls below 96 hours.
Therefore, before removing an operational battery, check the other battery first
to ensure that it is not calibrating. If you remove an operational battery while the
other battery is calibrating, the cache hold-up time for the ISE may be below 96
hours. Although the ISE does not enter Cache Protection Mode under this
condition, removing a battery while the other battery is calibrating may violate
the Emprise 7000’s guarantee of at least 96 hours of cache hold-up time.
