Troubleshooting the M7i Power System

When a power supply is functioning correctly, the green LED labeled OUTPUT OK is lit

steadily.

If any other LED states apply, consult the following topics:

Blinking or Off on page 85

Off on page 85

Troubleshooting the M7i Power System When the LEDs on All M7i Power Supplies Are Blinking

or Off

Problem If the LED is off on all 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 all power supplies. There is no power to the

router, so no LED is lit, including the alarm LEDs on the craft interface.

Solution Excessive system temperature is almost always caused by excessive environmental

temperature. Correct the environmental temperature before repowering the router.
