Step 1: Check CFEB LEDs

Three LEDs—a green LED labeled OK, a red LED labeled FAIL, and a blue LED labeled MASTER—indicate CFEB status.

Action

Look at the LEDs on the CFEB faceplate. The CFEB is located on the rear of the router above the power supplies (see Figure 233). Table 130 describes the CFEB LED states.
