Cisco MGX 8220 Shelf

The Cisco MGX 8220 shelf is a 19-inch rack-mountable unit conforming to the EIA RS-310-C standard and includes the following measurements:

•8.75 inches (5u) high

•17.45 inches wide

•21.25 inches deep (without cards) or 23 inches deep with back cards and fan connector

The shelf contains a card cage with 16 slots. The slots are numbered 1 to 16 from the left looking at the front of the shelf.

A backplane runs across the card cage spanning all 16 slots. The backplane is positioned approximately 14 inches from the front of the cage allowing a function module card to be inserted in the slot from the front and a smaller line module card to be inserted in the slot from the rear.

Slots 1 and 2 are reserved for BNM cards (single or a redundant pair) and slots 3 and 4 are reserved for ASC cards (single or a redundant pair). Slots 15 and 16 are reserved for the SRM (single or redundant pair). Slots 1, 3, and 15 work together as an active or standby set. The same is true for slots 2, 4, and

16.Slots 5 to 14 (10 slots) are available for service modules (or IMATM modules). For 1:N redundancy of T1/E1 service modules, standby cards must use slots 12, 13, and 14.

The shelf can house redundant power entry modules, which are small cards installed horizontally in the bottom rear of the shelf. The Cisco MGX 8220 shelf is powered by –48V DC power sources (single or redundant pair). Each power entry module is equipped with a circuit breaker. The shelf also provides a power receptacle for a cable to the cooling assembly, which is mounted in the rack below the Cisco MGX 8220 shelf (or shelves).

The backplane provides redundant system buses for communication between slots, power distribution to all slots, and communication between front and back cards. Figure 2-1and Figure 2-2show the front and rear views of the Cisco MGX 8220 shelf.
