Midplane - Cisco ASR 5500 Installation Manual

ASR 5500 Hardware Platform Overview
Midplane ▀

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.
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 or 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.
