Power Supply Redundancy
The Broadmore 1750 has two power input connectors for receiving –48 VDC. The user
may provide power to these connectors from different sources as one form of
redundancy. Carrier Access offers an optional dual AC power supply with 110 VAC,
and provides two sources of –48 VDC to the Broadmore 1750. This is power supply
contains two independent modules, each sufficient to operate the Broadmore 1750.
These modules are hot-swappable, and they may be connected to different sources for
an additional degree of redundancy. There is no impact to the Broadmore 1750 as long
as one (or both) of the modules is operating normally.
