Chassis Control Module
The Chassis Control Module performs management and monitoring functions for the
G10 CMTS, and it provides a single access point for operational and maintenance functions.
In addition, the Chassis Control Module runs the Routing Engine.
The Chassis Control Module connects with the Hard Disk Module in the rear of the chassis
through the midplane. This provides an Ethernet port at the rear of the chassis as well as the
front. See “Hard Disk Module” on page 55 for more discussion.
Figure 15 on page 39 shows the Chassis Control Module front panel.
