All LEDs on Both Supplies are Off

If all LEDs are off on both power supply faceplates, either someone has switched off power to the router or the system temperature has exceeded the acceptable maximum. In the latter case, the Routing Engine shuts down both power supplies. There is no power to the router, so the alarm LEDs on the craft interface are not lit.

Excessive system temperature is almost always caused by excessive environmental temperature. Correct the environmental temperature before powering the router on again.
