Fibres giving us grief !
So far the setup is that we have 2 fibres going from our switch cabinet to downstairs where our servers are but for 3 days now they are just losing connection but if we remove them and plug them back in they re-connect. Would it be because there is too much data but it has also happened over night when the system is doing very minimal, there appears to be no exact time when this occurs.
We have looked for network loops but there is nothing and for it to drop out over night this looks unlikely.
Dodgy fibre panel? Power issues? could be a number of things.
Are you certain that it is not an issue with one of the switches or one of the gbic modules??
Couple of things you need to try here if your certain its the fibre.
1. Remove the connector, and with a lint free cloth gently clean the end of the fibre using a very small amount of ethanol (from your science techs, pure ethanol, not the stuff they mix with water to dilute it for kids to use) do this on all ends.
2. With a ear bud apply a small amount of ethanol and gently clean out the receiver end on the fibre panel to remove any unwated artifacts.
3. Call the people who installed the fibre to come and run some test on the continuity of the connection as it may have been damaged somehow.
Unless your skilled in the dark art of fibre then don't mess too much with it, get a professional to sort it.
What sort of switches are they?
Is it a new setup that's always had problems or an exisiting setup that's suddenly stopped working.
What type of fibre, and what ends are they terminated with??

Sorry, existing setup that has only just started to play up.
I am skilled in the dark art of fibre, however I still get people to do it for me as if I break it, I fix it at my cost, they break it, they fix it!
