Either two AC or two DC power trays (cannot mix AC
and DC power trays)
Power Trays
Up to 8 power modules can be installed, and only 4
are needed to be active at any time. This allows
support for 4+4 power redundancy and A and B
battery plant dual feeds redundancy.
DC
Up to 8 power modules can be installed, and only 3
are needed to be active at any time. This allows
support for 3+5 power redundancy by using two
independent AC power sources (4 feeds each).
