Deployment Scenario 3: Adding a New PE Unit to an Existing PE Ring
- Consider the following PE ring with five PEs.

An SPX port with a live
link cannot be disabled, so you must physically disconnect the cable from that port
first. In this example, the PE ring is split between PE 21 and the CB active controller.
After the cable is removed from the live link, ports 1/1/23 and 21/2/3 go down, and
the PE ring state changes to BREAK.
