Redundant Power
Supplies
Two redundant power supplies are provided, each with an independent
AC In connector. If one supply fails, the load is transferred to the
remaining supply without interruption of service. To take full advantage of
the redundant supplies, Harmonic recommends that you use separate,
isolated power sources for each AC input.
Filler Panels
Filler panels may cover the slots for I/O modules when the chassis ships
from the factory.
Power supply LED states
The power supply LED can help you determine the state of the power supply.
