Chassis
The ASR 5500 is a 21RU, 19" rack-mount midplane-based chassis with input/output (I/O) and processing cards in the
rear, and fabric cards in the front. Two ASR 5500 chassis fit into 42RU of rack space. However, the typical deployment
will be a single chassis per rack with other equipment in the same rack.

will be a single chassis per rack with other equipment in the same rack.
The rear cards are larger and used for chassis management, I/O and session processing. The smaller front cards are used
for fabric crossbars and persistent storage. There are 10 slots at the front and rear of the chassis.
for fabric crossbars and persistent storage. There are 10 slots at the front and rear of the chassis.
The rear slots have a common midplane connector that is shared between the supported cards. This allows for different
