Re: Problem with Cisco 4507R

I am suspecting the extraction fan is running low RPM or is blocked.

Power off one of the PS (not the entire chassis), wait for 5 seconds and power it back on.

Make sure both PS do not sound like loud squeeking or squeeling sound.

Problem with Cisco 4507R


Thank you for feedback.

I already tried power up one of each time, but still problem.

Before this time, i did not change any on this chassis.

Problem with Cisco 4507R

Any one please help?


Problem with Cisco 4507R


See this:

Table A-8     1400 W AC-Input Power Supply LEDs




Green—Source AC voltage is OK. (Input voltage is 85 VAC or greater.)

Off—Source AC voltage falls below 70 VAC, is not present, or the power supply is turned off.


Green—Power supply fan is operating properly.

Off—Power supply fan failure is detected.


Red—Problem with one or more of the DC-output voltages of the power supply is detected.

Off—DC-output voltage with acceptable margins.

Note For proper operation of the OUTPUT FAIL LED, systems with single power supplies must be configured with a minimum of one fan tray assembly and one supervisor engine. Systems with dual power supplies must have a minimum configuration of one fan tray assembly, one supervisor engine, and one additional module. Failure to meet these minimum configuration requirements can cause a false power supply output fail signal.

Hope it helps.

How did you fix this problem.?


New Member



In my case, the fans on left chassis is very dusty. I shutdown the Switch and cleaned the fans after that all status is fine.

You also should see the status of all light where is the light warning then focus that problem.

Hope this can help you.

4507R+E both PS are showing "output fail" and switch stops working. (Switch photo attached).

Powering OFF and ON both the power supplies fixes the probem for few days.

After powering off and on, PS and FAN status shows ok

This problem has repeated twice now.
