EX3200-24T transceiver not plugged in

‎06-30-2014 07:45 PM

Hi,

 

Recently I purchased 2x EX3200-24T switches. I've configured and setup the swtich all is fine until I install SFP for the swtich.

As long as I installed 1 SFP to the swtich one of the ethernet port will show transceiever not plugged in.
If I plugged in one more SFP another port will show same error again.
Can anyone tell me why is it happening?

Are your transceivers compatible with juniper ?

check the output of the optics diagnostics when they are inserted.

 

show interfaces diagnostics optics INTERFACE-NAME

Yes they are compatible models. I just took out from my old switch which is same model is the new switch that i'm trying to deploy now.

The problem is not about fibre. The fibre is fine but only normal ge interface 20-23 will show no transceiver plugged in error according to which port of fibre i use. If i installed all 4 fibre all 20-23 ports will go down.

Accorind to Juniper there are some problem with EX3200 model but I want to know is why it works on my old switch which is exactly the same model as the newly purchased one.

A few things to look at. First have rebooted the switch since noticing the issue? If no reboot the switch. Next verify the version of Junos allows functioning with that SFP module. With little SFP experience, i would say look at this article and see if anything jumps out.

I think this is the problem. There is no solution for it unless i change my uplink module.

I remember this limitation now that you mention it.  The device is 24 ports only not 26 ports so you have to choose which to use.

 

The EX4200 does not have this limitation.
