Cisco XR 12410 Router Installation Guide
OL-13832-01
Chapter 4 Troubleshooting the Installation
Troubleshooting the Power Subsystem
Step 2 Make sure the router is powered on and that all power cords are connected
properly. Check that the:
• Power cords on the horizontal trough on the back of the chassis are secured
in place with their retention clips.
• Power cords at the power source end are securely plugged into their own
AC
power outlet.
• Source AC circuit breaker is switched on.
Step 3 Check the power supply status LED indicators.
• Pwr OK (green)—Indicates that the power supply is operating normally, and
both the source AC input voltage of 200
VA C t o 2 4 0 VAC, and the –48 VDC
output voltage to the backplane are within the nominal operating range. This
indicator lights when the power switch is set to the on (1) position.
–
If the Pwr OK indicator remains off after checking all of the power
sources, replace the power supply with a spare.
–
If the spare power supply does not work, replace its power distribution
unit (PDU).
• Fault (yellow)—Indicates that the system has detected a fault within the
power supply. This indicator remains off during normal operation.
If the indicator is on:
–
Toggle the power switch off and then on. If the indicator remains on after
several attempts to power it on, replace the power supply with a spare.
–
If the spare power supply also fails, the problem could be a faulty power
shelf backplane connector. Power off the router and contact a Cisco
service representative for assistance.
• Temp (yellow)—Indicates that the power supply is in an overtemperature
condition, causing a shut-down to occur.
Note If the temp indicator is on, the fault indicator is also on.
–
Verify that the power supply fans are operating properly.
–
Verify that the blower module is operating properly.
If the power supply fans and the blower module are operating properly,
replace the existing power supply with a spare.
