• Fault. The BBU detected a fault. This occurs if the voltage or temperature

is outside the acceptable range.

•

Error. Other BBU error. Please contact LSI Technical Support.

•

Weak Battery. The battery should be replaced soon. The results of a

battery health test or capacity test indicate that the battery is below the

warning threshold (48 hours).

•

Failed Battery. The battery failed a test and must be replaced. A “Failed

Battery” status is displayed if the battery failed the health test or the

battery capacity is below the error threshold (24 hours). The battery must

be replaced.

Battery Voltage. Indicates the voltage status of the battery. The BBU

measures and evaluates the battery voltage continuously. If the voltage falls

outside the normal range, warning or error level AENs are generated. In the

case of a voltage error the BBU status will change to “Fault” and the battery

will be disconnected electronically.

Battery Temperature. Indicates the temperature status of the battery. The

BBU measures and evaluates the battery pack temperature continuously. If the

temperature falls outside the normal range, warning or error level AENs are

generated based on the measured temperature. In the case of a temperature

error, the BBU status will change to “Fault” and the battery will be

disconnected electronically.

Estimated Backup Capacity. Indicates the estimated backup capacity in

hours. This is the amount of time that the battery backup unit can protect the

data in the 3ware RAID controller's cache memory. This field is set to zero at

the start of a new test and is updated after the test completes. A capacity of

zero will also show if the BBU is disconnected and then reconnected.

Under optimal conditions, a battery can protect for up to 72 hours. However,

with a fresh battery, you may see a higher number in this field. As the battery

ages, the backup capacity diminishes.

Last Capacity Test. Indicates the date when the last battery test was

completed. To test the battery click the

Test Battery Capacity link. For

details, see “Testing Battery Capacity” on page 187.

Battery Installation Date. Indicates when the BBU last detected the battery

pack was removed and replaced.
