Juniper Networks MX480 - Manual (Page 184)

• Verify that the source circuit breaker has the proper current rating. Each power supply
must be connected to a separate source circuit breaker.
• Verify that the AC power cord or DC power cables from the power source to the router
are not damaged. If the insulation is cracked or broken, immediately replace the cord
or cable.
• Connect the power supply to a different power source with a new power cord or power
cables. If the power supply status LEDs indicate that the power supply is not operating
normally, the power supply is the source of the problem. Replace the power supply
with a spare.
