[orlandoegb]

Hello Community,

My Nexus 5548UP do not recognized the GLC-SX-MM (GE SFP, LC connector SX transceiver) Module  anywhere of  32 unified ports...

I need some assistance about that to setting my infrastructure attached on the diagram.

Thanks

Hi,

Some times, Cisco devices don't work with 3rd party optics.  Did you order the optic through Cisco or a reseller?

Is the fiber Ok?

Did you remember to set 'speed 1000' on those ports where you've inserted the SFP's?

Without it the Nexus will not recognise the module.

I fixed this issue by flip-flopping the fiber connectors.
