FPC LEDs and Offline Button
Each of the eight FPC slots in the router has two LEDs and an offline button located directly below it on the craft interface, as shown in Figure 7. The green LED labeled OK and red LED labeled FAIL indicate FPC status, as described in Table 5.
The offline button, labeled with the FPC slot number (for example, 4), prepares the FPC for removal from the router when pressed. Press and hold the button for about 5 seconds, until the FAIL LED lights.
