Dead Ports

Good morning,

 

Has anyone every seen a Fortiswitch with dead ports?  I have a standalone 448E (7.2.3) that has 3 adjacent ethernet ports that are dead.  When you plug anything into them you get no link lights.  All the ports are administratively up so thats not it either.

 

If anyone has an diagnostic or otherwise suggestions or comments, I'd really appreciate it.  This units support contract has expired so I can't contact Fortinet about it.

The only solution is to renew the support contract and RMA this device. I don't see a way how to revive these ports.

It's a standalone switch so none of that troubleshooting will work.

Please check to change the cable on those ports. If no progress then try to reboot the switch and check if the LED blinks.

You can use the these commands to see if they give you some more details what's happening "# diagnose switch physical-ports xxx port" like:

# diagnose switch physical-ports cable-diag port2

Dealing with copper and other devices with electrical grounding problems it can fry up the port, it's rare but it happens. In case this link is used to connect end host check the host, if this link connects different part of networks (different buildings) optical fiber is recommended.

It appears those ports (13, 14 and 15) are fried.  Symptoms started when a printer stopped accepting jobs like it was disconnected from the network.  Checking the cables, replacing the ethernet cable, etc didn't resolved however when I switched to a new port in the same vlan it came up and has been working normally since.  Moving it back in the original port and its dead.  Through trial and error we found those 3 ports didn't work as the should.   Other than the diagnose commands I ran below, I'm unsure if there is any more that might help expose what the problem is.

Yeah..I was just hoping that I could get verification from the switch itself that those ports are toast.  I'll see about renewing the contract and sending it in for repair/replacement.
