5 Power System
The DC Power System powers the Mediant 8000 from the DC power sources. It
consists of the following hardware components:
PEM/DC/8K Power Entry Module
PS/DC/8K Power Supply Module
5.1 PEM/DC/8K Power Entry Module
PEM/DC/8K Power Entry Modules are used for connecting the Mediant 8000 chassis
to the DC power sources. Two PEM/DC/8K modules are installed in the back of the
chassis and enable chassis connection to two independent DC power sources. Such a
connection provides chassis power high-availability in the event of DC power source
failure. Each of the DC input terminals is reverse current protected.
