Avaya G650 Media Gateway
The Avaya G650 Media Gateway is a fourteen slot, rack mounted carrier configured for TN form
factor circuit packs. The G650 Media Gateway is used with the S8500 and S8700-series Media
Servers.
Detailed description
The G650 is 8U or 14 inches (35.6 centimeters) high and mounts in a standard 19 inch (48.3
centimeters) data rack. The G650 uses one or two 655A power supplies, operating on AC and/
or DC input power. Either power supply can provide all the power needed by the G650. When
two power supplies exist, they share the power load. One power supply can operate on AC
power and the other on DC power. However, each power supply has its own AC power cord so
that both power sources can power the Media Gateway simultaneously. Both power supplies
can take input power from the DC input cable if their AC power fails.
The system will always use AC power if available.
See Figure 41: G650 Media Gateway on page 175 for an example of the G650 Media
Gateway.
