Battery Backup Configuration

NOTE During the initial calibration cycle for a BB4050 module, the

controller disables automatic, low-battery write-through mode.

After the calibration, use the Battery Backup Configuration

dialog to set a threshold for entering write-through mode when

the battery charge drops below a predetermined level.

This option lets you view the status of the BB4050 Battery Backup Module

and set operating parameters when the battery capacity reaches a

predetermined level. The battery Status and available Backup capacity (in

hours) is displayed. The Backup value is monitored periodically by

software and changes whenever the battery pack is charging or

discharging.

The Backup Capacity Warnings parameters let you activate the following

options when the BB4050 module reaches a predetermined level of

remaining backup capacity (in hours). The capacity warning thresholds

can change depending on the capacity and number of memory modules.

Generally, more cache will result in lower battery backup capacity.

Low: Auto Write-Through

When checked this option automatically sets the cache to write-through

mode when the specified number of hours (Hrs.) of battery capacity

remain. The number of hours must be greater than or equal to the number

of hours for a Predictive Failure Warning.

Predictive Failure Warning

When this option is checked a warning message will be issued when the

battery backup capacity is almost depleted. Enter the number of hours

(Hrs.) of remaining backup capacity when this message should be issued.
