Does any know of an inexpensive alternative to a Dell 6024F switch. I have bought and tried 2 of these units and they continue to not work in my environment.

My Environment:
IT Room where Main Router and Dell 6024F reside
Remote bldg within 1500 feet from IT Room
MM 50/125 Fiber Cable from remote bldgs back to IT room
Industrial unmanaged 4 port Ethernet Switch w/SFP module at each remote bldg.
All Fiber cables terminate to Dell 6024F switch


Problem:
Fiber cables between unmanaged switch at bldg and Dell 6024F link up at first and after a few days it no longer works.  They will just will not link up and transfer data.  I can take another unmanaged switch just like at the remote bldg and it links up just fine and transfers data with no problems.

Solution:
????? Not sure, since I have tried 2 Dell 6024F and afraid to buy another one.  

I had posted a problem before that I thought I resolved by buying another Dell 6024F but I was WRONG.

Is there anything in the logs on each switch when the link drops?

What fiber modules are you using?

Are the fibre patch leads the same spec as the main fiber run?

How long is the fiber run?

Have you had the fiber tested?

How long does the other unmanaged switch work for?

Thanks for the response.

Nothing in the logs on the Dell 6024F and the other switch is unmanaged.

Dell SFP Module: 1000BASE-SX SFP 850nm 550m transceiver

All Fiber cable is LC/LC MM DUPLEX 50/125

The 2 fiber cable runs I have at the moment are 1050 ft and 1455 ft.

The 2 long runs above were tested and passed.

The unmanaged switch has a SFP Module as well and is 1000BASE-SX SFP 850nm 550m transceiver.

I switch out the SFP modules on both ends just to test. same result, no link. As soon as I plug the fiber up to either the Juniper NS-500 fiber port or another matching unmanaged switch it links up no problems.

- thanks, Shawn

If you reboot the Dell switches does the link come back on?

No, rebooting Dell does not change anything. Still no link up!

Ok, I tried one more test.  I hooked up the unmanaged switch with nothing else plugged into it on the other end and connected it to the Dell 6024F via 1500 ft MM Fiber cable.  Rebooted Dell switch and it linked up.  I checked it the next day and it was still linked up. I check it again today and it was no longer linked up.  I am lost on what to do.  I think I might try a different unmanaged switch.

Anyone, any suggestions?

-Thanks, Shawn

Turn off STP on each Dell switch and see if it stays up.  If it does you may need to review the STP configuration.

OK, I disable STP on port G2 and I have that port connected to an unmanaged switch at 1500 ft away via MM Fiber cable. The link is up for now. I will physically inspect the link again tomorrow and report back my findings.

-Thanks, Shawn
