6.2 UPS Support

UPS status monitoring is available from firmware release 3.34

onward. This feature enables the RAID subsystem to observe and

respond to the status of the UPS (battery charge or AC power) by

dynamically switching the write policy.

Requirements for UPS Status Monitoring:

1. Connect the UPS device to the controller/subsystem’s COM2

serial port.

2. Set the same Baud Rate to the system COM2 and the UPS serial

port. Please refer to Chapter 3, RS-232C Serial Port Settings.

3. Set the UPS option in the 6.1.1.1 to “Enabled.”

Condition Reports and Reactions:

1. When mains power is lost or when the UPS charge is low, an

event is issued; the subsystem commences an auto cache-flush

and is forced to adopt the Write-Through mode.

2. When the serial port connection is lost or when the UPS is

removed, an event is issued to notify the system manager that

the external UPS is absent.

3. When the UPS battery charge or mains power is restored to a

safe functioning level, the subsystem automatically restores the

original write policy.
