NonStop System With Rack-Mounted UPS and Data Center UPS in Parallel
shows an example of a non-supported configuration in a NonStop system with the left
PDUs connected to the rack-mounted UPS, and the right PDUs connected to the data center
UPS. In this configuration, OSM manages and monitors the rack-mounted UPS. However, OSM
does not manage or monitor the data center UPS.
Figure 38 NonStop System With Rack-Mounted UPS and Data Center UPS in Parallel
When the utility power fails, OSM detects a
UPS AC Input not Present
event from the
rack-mounted UPS. OSM does not recognize the data center UPS. OSM does not detect that
the data center UPS is running on battery and the UPS battery runtime. OSM does not initiate
the controlled shutdown of the I/O operations and processors.
•
The rack-mounted UPS shuts down before the data center UPS.
•
If the utility power is not restored before the data center UPS shuts down, any data in the
NonStop system disk drive write cache that has not been transferred to the disk drive media
is lost.
