Power requirements
For Avaya G860 media gateway with Trunk Processing Module, 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.
The following are 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.
Electro magnetic compatibility
Table 22: G860 + TP-6310 Chassis Dimensions (continued)
Dimension Value
Depth without projections 30 cm (11.8 inches)
Weight (fully loaded) 20.45 kg (45.1 lbs)
The chassis is designed to comply with known EMC/RFI standards, including FCC Part 15,
Class B; ICES-003, Class A; EN 55022, Class B; EN 300 386.
Compliance measures include:
● Venting holes - for intake and exhaust, sized to provide for blockage of frequencies within
the specified range
● Blank panels with contact fingers - used for covering empty slots when a configuration
requires this
● RFI filters - built-in to the DC power inputs, assuring that conductive interference does not
reach the power supply modules, or that switching signals generated by the power supply
modules do not propagate over the main feed
● Air filters - integrates a honeycomb EMI shield in its assembly. The honeycomb structure
consists of "cells" that are engineered to trap and absorb EMI noise while maintaining 95%
to 99% aperture for minimal airflow impedance. A gasket installed around the frame makes
sure there is conductivity of the frame to the enclosure.
