Performing Preventive Maintenance
The Parallel Capacity/Redundant system requires very little preventive
maintenance. However, the system should be inspected periodically to verify that
the units are operating normally and that the batteries are in good condition.
Perform the following checks DAILY:
•
Check the area surrounding the Parallel Capacity/Redundant system. Ensure
the area is not cluttered, allowing free access to the unit.
•
Ensure the air intakes (vents on the front doors) and exhaust opening
(on top of the UPS cabinet and SSBM) are not blocked.
•
Ensure there is at least six inches of clearance behind the unit for proper air
circulation.
•
Ensure the operating environment is within the parameters specified in
Chapter 16, “Product Specifications.”
•
Ensure the SSBM and UPS modules are in Normal mode (Normal status
indicator is lit). If alarm lamps are lit or the Normal status indicators are not lit,
contact Powerware Customer Support.
Perform the following checks MONTHLY:
•
Ensure all status indicator lamps are operative. (Press the
and
pushbuttons simultaneously to test the lamps.)
•
Monitor system parameters as described in Chapter 9, “Using the Control
Panel.”
•
Check the air filters in UPS modules (located behind the front doors) and
replace them as necessary. The filter size is 16
