Determining SCG Mastership

If both SCGs are installed and functioning normally, SCG0 is master and SCG1 is backup. Removing the backup SCG does not affect the functioning of the routing node. Taking the master SCG offline might result in a brief loss of SONET clock lock while the backup SCG becomes master.

Steps To Take

To determine which SCG is operating as the master, follow these steps:

1. Display the SCG Master from the Craft Interface Output
2. Look at the SCG LEDs on the Faceplate
