Each rectifier assembly can supply up to 50 amps of DC current. A minimum of two rectifiers
are installed in each DC power cabinet to supply a total of 100 amps. A third rectifier assembly
can be installed and is used as a backup (N+1). Each cabinet can pull up to 18 amps. Up to 3 DC
power cabinets can be stacked to supply power to media gateway stacks.

shows a typical power and ground layout for a
DC power system without a J58890CG DC Power Distribution Unit. The J58890CG is required
if the distance between the DC Power cabinet(s) is greater than 30 feet (9 m). ‘‘Connections
Using DC Power Distribution Unit’’ on page 110 shows a typical power and ground layout for a
DC power system containing a DC power distribution unit.
