Battery replacement guidelines
Each controller contains a sealed battery that provides backup power to
cache memory. You must replace the battery every three years.
Note: Do not disassemble the battery; otherwise, you could get burned or
receive a shock.
If the storage system does not receive power for more than six months, the
battery can become discharged and possibly damaged. To avoid this
situation, charge the battery for more than three hours at least once every
six months.
Checking for loose or damaged cables or connectors
It is good practice to check cables for damage on a periodic basis. Confirm
that all cables and cable connectors are in good condition and connected
securely to the appropriate interfaces.
Restarting the storage system
Before restarting the storage system, wait at least one minute with the main
switch off (amber

104ºF (40ºC) or higher because battery life will be shortened.
