configuration with full power for as long as the router is operational. In the two-PEM
high-line configuration, slots
configuration requires two power supplies, with the third and fourth providing
redundancy. With high-capacity power supplies, you must have a minimum of two
power supplies installed in the router.
Each AC power supply faceplate contains three LEDs that indicate the status of the
power supply (see Table 13 on page
LEDs on the craft interface. In addition, a power supply failure triggers the red alarm LED
on the craft interface.
State Description
Off AC power input voltage is below 78 VAC.
On AC power input voltage is within 78–264 VAC.
Off DC power outputs generated by the power supply are not within the normal
operating ranges.
On DC power outputs generated by the power supply are within the normal operating
ranges.
Off Power supply is functioning normally.
On Power supply is not functioning normally and its output voltage is out of regulation
limits. Check
