Overview

The Cisco MGX 8220 is a 19-inch rack-mountable shelf. This shelf provides 16 slots for holding the modules (card sets) that provide the functionality. Each slot is designed to house two cards, a front card and a back card. Cards are installed in a slot as a two card set. A backplane runs across all 16 slots to provide signal connections between front and back cards, and between slots. The backplane also provides power distribution to all slots from dual (redundant) power entry modules installed in the bottom of the shelf.

All external line connections are made on the back cards at the rear of the shelf. These include Frame Relay lines, the ATM trunk line, and RS-232 lines for the control console.

The Cisco MGX 8220 includes the following common equipment:

•Cisco MGX 8220 shelf

–Card cage

–Backplane

–Power entry module housing

•Core cards installed in the shelf

–Cisco MGX 8220 shelf controller (ASC)
