Hi All,
I'm currently setting up a distribution network for my company. I have two 2910 which will be installed on 2 different floors.
I've add two X121 Gbic for the connection between the 2 switches.
In the lab : 2 switch connected with a LC-LC fiber (62um) - Forced the Gbic port from Auto to 1000FDx and they come up.
Everything is tested and OK.
My issue :
When the switches are installed in the rack on different floors, connected to the building fiber network with fiber cords => Gbic ports are not coming up...
I've changed the fiber cords, cross the plugs... Nothing happens
My Questions :
- Is X121 Gbi the rigth choice and may be an issue ?
- I'm using OM1 fiber cord (62,5um) but not sure about the fiber type of the building . Could be a cause ?
- Do you see any other point I can check/change ?
Thanks in advance for your help.
Christophe
