Hi,
I am trying to configure a small network for NGO.
We have multiple Cisco ESW 520 that will be the link with fiber on a Catalyst 3750.
I have correctly configurated all ESW 520 with VLAN1 adress like 192.168.0.10 and netmask 255.255.240.0 .
I think i have correctly configurated the Catalyst 3750 with a VLAN1 address like 192.168.0.30 and netmask 255.255.240.0
But I have a problem, when we connecting all together, there's no fiber LED come on any switches to show connection or activity, and i can no ping the Catalyst 3750.
The VLAN1 is configurated for all fiber port on the ESW 520 and Catalyst 3750.
Here the show vlan command result :

Hi,
Now i find one of my probleme, i connect the wrong fiber module connector to the Catalyst 3750, and this bad action disactivated the GigabitEthernet Port.
Now I try to find the command to activate the Port who are desactivated by the using of a wrong module.

I try to shuting down and restart interface with the command "configure terminal" but no change, the port where i use the wrong connector stay off with no status led.
If you have an idea of other tips to do.
