Using the redundant configuration
Before using a redundant configuration, verify the following:
• HP UPS Network Modules and HPPP Clients are installed.
• The two UPSs are the same model.
• The combined load of UPS 1 and UPS 2 does not exceed 50% of the single UPS load rating.
The redundant UPS feature is designed to maintain power to attached Clients in the event of a utility power
fail condition to a single UPS. In the event of a single UPS power failure you might still experience a graceful
shutdown of Clients if one of the following conditions is present with the unaffected UPS:
• The unaffected UPSs has a fault condition (Internal Failure, Overload, Communication Failure) or is in
Bypass.
• The combined load of UPS 1 and UPS 2 exceeds 100% of a single UPS rated capacity.
• Both UPSs have a fault condition (Internal Failure, Overload, Communication Failure) or are in Bypass.
