2.3 The Chassis
The Avaya G860 Media Gateway configuration complies with NEBS Level 3
requirements (Avaya G860 Media Gateway chassis – designed to meet - approval
pending), and conforms to CompactPCI PICMG 2.0 standards. They each contain a
10-slot card cage. All component boards have a sturdy, hot-swap cPCI 6U form factor.
Boards are inserted from the front and the back and engage the midplane on either
side inside the card cage. Slots for the boards are numbered from one to ten on the
left of the card cage in the front, for identifying board placement. The midplane
contains slot keys to match the appropriate board. This prevents insertion of a board
in a wrong location.
The Avaya G860 Media Gateway chassis configuration also houses two fan tray
units, facing the front of the chassis, one is to the left of the card cage and another is
in the upper right-hand corner of the chassis.The fan tray unit to the left of the card
cage also houses an air filter. The chassis also holds three Power Supply modules to
the right of the card cage (under the second fan tray unit).
