2x MSL6060 - single power supply failure leads to FC card reboot

Hello team,
our customer has a problem with the power supply redundacy on two MSL6060.
Situation:
1/ when we disconnected (simulation of outage) lower power supply the NSR is rebooting
2/ when we disconnected (simulation of outage) higher power supply NSR is working properly without reboot

do you have any idea please?

Re: 2x MSL6060 - single power supply failure leads to FC card reboot

Is this a combination off two stacked MSL6030 with a pass through mechanism?

In this case each MSL6030 has its own PS and then it is a normal issue if your Fiber card is installed in the lower MSL

A normal MSL6060 has two power supply at the bottom left side

yes, that are regular MSL6060, two power suplies....

when unplug lower PS then NSR is rebooted
when unplug top PS then all is ok and NSR is not rebooted :-(

This is not normal because a normal MSL6060 has two PS (the one next the other) at the bottom left.

Check the figure in my link and double check with the customer

I know that is not normal. That is reason of my question :-)

right funcionality is clear:
fully redundance of NSR in case of outage one of the supply.

But what should I do when I don't have this funcionality?

Re: 2x MSL6060 - single power supply failure leads to FC card reboot

I can suggest two things:

1- you may have a defective power supply
2- you may have a bad power cable, or a bad electrical grounding

for the second case, I would suggest to check with a voltmeeter the voltage between the ground and the neutral pin and between the ground and the phase pin
you should have > 1 volt in the first case and ~ 220 in the second case. If you found ~110 volts in both case, you have a grounding problem, the same if you have more than a few volts between grounding and neutral.
I recommend to check this directly at the end of the power cable that enter in the library, so you check all including socket and cable.
(these value apply on an european environment where power supply is 220 volts)

To follow Marino's advises I would strongly recommend to involve real certified experts to check voltages etc ... just to be safe ...

As you know: safety rules ...

BTW, I know about ~230V and I remember my last contact with this ...

Hope this helps!
Regards
Torsten.

Hello,

there was a problem with power supply. CE replaced that and noe is working properly.

What is strange? There was the problem on two MSL6060...the same issue on the same higher power supply....

thanks for hints ans ideas
