What It Means

The sample output shows that the routing platform has two Control Boards online and functioning normally. The Control Board installed in slot 0 is functioning as master. If an amber asterisk displays, the Control Board has failed.

Alternative Action

To view the Control Board status, you can do one of the following:

• (T320 router and T640 routing node) Look at the router craft interface host module status or look at the LCD display for any Control Board alarms.

Table 72 describes the T320 router and T640 routing node host subsystem LED states.
