Troubleshooting the MX2000 Router Power System
date_range
09-Nov-20
Problem
Description: The following alarms, LEDs, and other conditions indicate a problem with the AC or DC power system:
If all AC, DC, universal power supply modules (PSMs) have failed, the system temperature might have exceeded the threshold, causing the system to shut down.
The yellow
PWR OKLED blinks when an AC or a DC PSM is out of the power limit or is in an overcurrent condition.The red
FAULTLED lights when the PSM is not receiving enough airflow to maintain the proper temperature.The red
FAULTLED lights when the AC or DC output voltages are not within range.The yellow
INP0LED blinks when the AC or DC voltage is present, but out of limits. This LED blinks continuously for approximately a few seconds on and a few seconds off.The yellow
INP1LED blinks when the AC or DC voltage is present, but out of limits. This LED blinks continuously for approximately a few seconds on and a few seconds off.The red
-48VLED lights when the wrong polarity of DC input voltage is connected on the DC PDM.NoteFor the universal power supply LEDs, see MX2020 High-Voltage Universal Power Supply Module LEDs and MX2010 High-Voltage Universal (HVAC/HVDC) Power Supply Module LEDs.
Solution
To troubleshoot the MX2000 router power system:
- Check the LEDs on all AC, DC, or universal PSM faceplates.
PWR OKPSM LED is blinking—Check the fans and air filters to be sure that they are functioning and providing sufficient airflow through the chassis.PWR OKPSM LED is off and no red alarm condition exists—Check that the circuit breakers are switched to theONposition. Check that the AC or DC power switch is in the on (|) position.PWR OKLED on PSMs is not lit—Check that the PSMs are inserted and are operating.If an AC PSM, or a DC PSM, or a universal PSM is correctly installed and functioning normally, the
PWR OK,INP0, andINP1LEDs light steadily, and theFAULTLED is not lit.
- Check the LEDs on each DC power distribution module (PDM)
faceplate.
–48Vor 240 V China PDM LED is off—Check that the PDM is receiving voltage.–48Vor 240 V China PDM LED is lit red—Check that the PDM is connected to correct input voltage and polarity.NoteThis does not apply to the 240 V China DC PDM.
Check that the DC PDM switch is set to
60 Aor80 Adepending on the current feed coming from the DC source circuit breaker.–48Vor 240 V China LED on a DC PDM is not lit—Check that the input is receiving source DC power.If a DC PDM is correctly installed and functioning normally, the
–48Vsource input LEDs light green steadily.
- Check the LEDs on each AC PDM faceplate. There is one
LED for each input feed. See Mapping Input Power from AC Power Distribution Modules to AC Power Supply Modules on MX2000 Routers.
On the three-phase delta AC PDM, the left arrow (
←) green LED is lit steadily, indicating that the left input feed is receiving voltage.On the three-phase delta AC PDM, the right arrow (
→) green LED is lit steadily, indicating that the right input feed is receiving voltage.On the three-phase wye AC PDM, the left arrow (
←) green LED is lit steadily, indicating that the left input feed is receiving voltage.On the three-phase wye AC PDM, the right arrow (
→) green LED is lit steadily, indicating that the right input feed is receiving voltage.On the single-phase AC PDM or universal PDM, the green LED for each feed is lit steadily, indicating the input feed is receiving voltage.
- Verify that the source circuit breaker has the proper
current rating. Each PDM must be connected to a separate source circuit
breaker. Check that the AC or DC circuit breaker is in the on (
ON) position. - Verify that the DC power cable, or the AC power cord, or the universal power cord from the power source to the router is not damaged. If the insulation is cracked or broken, immediately replace the power cord.
- Connect the PDM to a different power source with new power
cables. If the PSM
PWR OKLED still does not light, the PSM is the source of the problem. Replace the PSM with a spare.If the
PWR OKLED on the installed spare does not light, the replaced PSM might be faulty. To return it for replacement, see Contacting Customer Support. - Check the status of a PSM, issuing the following CLI command.
The value
Onlinein the rows labeledStateindicates that each of the PSMs is functioning normally.NoteFor the MX2010, the PSMs are referred to as
PSM0throughPSM8.For the MX2020, the PSMs are referred to as
PSM0throughPSM8(bottom) andPSM9throughPSM17(top).Here is an example of the AC PSM input status for an MX2020:

This is the case even if one negative input source is switched off through a breaker.
NoteFor midpoint impedance grounded source, the CLI display of the input voltage is inaccurate for the input source with lower input voltage. For example, if one source is +/-120V, and the other source is +/-125V, the CLI input voltage display is 250 V for one input, and is 245 V (should be 240 V) for the other.
Here is an example of the universal PSM (HVAC/HVDC) input status for an MX2020:

- If all PSMs have
failed, the system temperature might have exceeded the threshold,
causing the system to shut down.Note
If the system temperature exceeds the threshold, the Junos OS shuts down all power supplies so that no status is displayed.
The Junos OS also can shut down one of the power supplies for other reasons. In this case, the remaining power supplies provide power to the router, and you can still view the system status through the CLI or display.
