Dell 6024 and LNX-501AG-SFP-T switch not linking up

I have the following equipment that will not link up via MM 50/125 Fiber Optic.


Switch 1:  Dell 6024F
Switch 1 SFP Module: 320-2881 SFP module
(http://www.ourfiber.com/320-2881-p-133.html)

Connected via Multi-mode 50/125 Fiber optic cable.

Switch 2: LNX-501AG-SFP-T
(http://www.aaxeon.com/products/industrial-ethernet/gigabit-switches/unmanaged-switches/2168)

Switch 2 SFP Module: SFP-M-T
(http://www.aaxeon.com/products/sfp-modules/gigabit-modules/212)


The Dell 6024F will not link up and I have changed from Auto Negotiate to manual 1000G Full Duplex. On the Gb ports, that is the only option (Auto or 1000Gb/Full).  Either way, no link light.

I have confirmed that both switches and SFP modules work by connecting to other devices.  I just need to figure WHY they are not playing nicely together.

Any help or ideas would be appreciated.

Does the Dell 6024F work on its own?

Have you tried in another order. LNX-Dell-SFP?

Since the LNX-501AG-SFP-T  seems to be unmanged, I am assuming it is Auto/Auto, so I would change the Dell switch back to auto/auto.

What were the other devices that you tested with?

Did you use the same cable?

When the dell is in auto there is no link light. The dell works perfectly with a juniper ns-500. I tried several different cables. The unmanaged LNX switch works with another LNX switch.

The LNX switch works with the Juniper ns-500.  I need to know what to change on the Dell to get it to work.

Any Ideas?

After further testing, we came to the conclusion that the Dell switch was not working properly. We purchased another Dell6024F switch plugged it up and all remote fiber switched linked up with no problems.

We appreciate everyone's help.

No other config solution worked out. Replacing the device was the only solution.
