OmniSwitch Backup Power Shelf/System (BPS)
OS-BPS Connector Priority
If the total available PoE or system power drops below the minimum budget required for the current
configuration, the OS-BPS automatically powers off switches according to priority until the configuration
falls within the available power budget.
If the total available PoE or system power later increases to meet the power demands of the configuration,
the OS-BPS returns power to those switches based on priority.
Connector priority for all OS-BPS connectors is user configurable. This allows the user to specify which
switches will remain operational in the event of a power budget shortfall.
By default, connector 1 receives the highest priority and connector 8 receives the lowest priority.
Additional default priorities are specified below.
