POE smart disables working port?

[mtngoat]

Running firmware 1.3.3rc5.

On my WS-8-250-DC, my uplink port became disabled (in the past, POE smart disabled the port), so I lost remote communication. I thought it might be low battery issue, but upon making the trek up the mountain, I noticed the other two ports powering equipment were working fine. I powered off the Netonix and moved my uplink port to one of the ports that was still being powered. I reconnected power and received remote access again.

What do I do so this doesn't happen? If I set a ping watchdog, then the port would unpower the port for 5 seconds and repower and hopefully restore access. But if POE smart has already disabled power on the port, this wouldn't help. Do I turn off POE smart?

Or what other scenario would have turned power off on the port?

I am not quite following your post, if I remove the text in red I can follow this below;

You lost your uplink port

You went to site and backhaul port powered OFF.

At this point did you check the LOG to see why the port was powered OFF? <- IMPORTANT TO DO


Are you saying that ping watchdog rebooted a port then POE Smart disabled the port?

I lost my backhaul port.

Went to site and unpowered and repowered after moving cables. I didn't take laptop, so I didn't see logs. I will enable syslog for future logging.

I didn't have ping watchdog enabled. I was just wondering if the port gets powered off, would ping watchdog bring it back online.

I will report back if it happens again and I have the log of what happened.

POE Smart does not turn POE off once it is ON.

POE Smart "only" checks the cables for a cross short when you save/apply POE to a port and also on a cold reboot of the switch POE Smart will check for cross shorts.

Once a port is up and running it will NOT turn the POE off. AT this point POE Smart is not even running it only runs when you enable POE on a port or during boot.

This is some place where you really need to check the switch LOG to see what happened. Who knows maybe someone hacked into your switch and turned POE OFF which would have shown up in the LOG and from what IP address.

But no, if POE smart turned POE OFF during a cold boot or on a port turn up a ping watchdog would not turn it back on because there is a cross short.

I think you are blaming this on POE Smart and there is no way it had anything to do with it from what you describe. - NEED TO LOOK AT LOGS NEXT TIME

Thanks for the insight. I will do more research next time before posting.
