M5 and M10 Routers LEDs

Component LED Location

PICs 1 LED per port, with 4 states: Red, Green, Amber, Off PIC faceplate
Power supplies Blue OUTPUT OK Power supply faceplate

Alarm LEDs

Red alarm Large circular red Craft interface
Yellow alarm Large triangular amber Craft interface

Red alarms occur when the router is started if no device is physically connected to the management fxp0 interface or if two power supplies are
physically installed but only one is switched on.

Backbone Router Hardware Installation Guide quick-connect terminals; grounding

cable attaches to single-hole cable lug

Taking Components Offline

Component Procedure

PIC 1. Press the PIC offline button, located on the PIC faceplate.

2. Press and hold the button until the PIC LED lights red (about 5 seconds).

3. Press and hold the offline button again after installing the replacement PIC to bring the PIC online.
