Midplane
The midplane within the ASR 5500 chassis interconnects rear input/output ports and processing cards with front fabric
cards. The larger rear cards support chassis management, input/output, and session processing. The smaller front cards
provide fabric crossbars, persistent storage and system status monitoring.
cards. The larger rear cards support chassis management, input/output, and session processing. The smaller front cards
provide fabric crossbars, persistent storage and system status monitoring.
The rear slots have a common midplane connector that is shared between the supported cards. This allows for different
mixes of input/output and processing capacity depending on the customer's intended use. The two MIO/UMIO slots (5
and 6) have additional midplane connections to perform chassis control operations, including support for a serial
Console port and dual remote management ports.
