Power Consumption

DC Input Power
For the Avaya G860 Media Gateway, the average power consumption for a full
complement of boards is approximately 696 watts (14.5 A at 48 VDC).
Two Power Entry Modules (PEM) are provided for DC connections on the rear of the
chassis. Power is required to be between -40.5 and -60 VDC. Each PEM unit contains
one input terminal. Each of the DC input terminals is reverse current protected. The
input terminals on each of the PEM units provide redundancy protection for the power
entry circuitry.
Recommendations for DC Power input:
When using DC power as the primary input, ensure that the power supply complies
with the safety requirements of Call Agent CAN/CSA-C22.2 No. 60950-00 and UL
60950, and EN 60950.
For High Availability, connect two separate DC power sources to avoid total power
failure if one of the DC power sources fails.
For AC, only one PEM is to be installed in the system.
Recommendations for AC Power input:
It is recommended to connect the AC power source to a UPS to avoid total power
failure if the AC power source fails. This is mandatory for high availability (i.e., on
redundant system configurations).
Connect AC-powered systems only to earthed power outlets.
Connect the chassis to the facility's earth, using the earthing terminal(s) provided.
