To convert and connect the control planes of an operational T640 router (see Table 24
on page 173 for the TX-CIP and T-CB ports to connect):
Determine which host subsystem is functioning as the master or the backup by using

one of the two following methods:
Check the Routing Engine LEDs on the craft interface. If the green
lit, the corresponding host subsystem is functioning as the master.
Issue the following CLI command. The master Routing Engine is designated

The Routing Engine paired with the T-CB immediately assumes Routing Engine
functions, and there is no interruption to packet forwarding.
Replace the other CB (which now belongs to the backup host subsystem) with a T-CB.
