What It Means

The command output displays the SCG LED status. The router has two SCGs installed. Asterisks (*) indicate the operation status. The color represents the possible SCG operating states: Amber (Fail), Green (OK), and Blue (Master). Both SCGs are functioning properly (Green). The SCG in slot 0 is operating as master; the SCG in slot 1 is the backup.
