Power supplies (0, 1
from left to right)
Two redundant, hot-swappable 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 to service. To take full
advantage of the redundant supplies, Harmonic
recommends that you use separate, isolated power
sources for each AC input.
