Problem with Procurve Switch 4108GL

[Jay Mia]

Can someone please help, I have a HP Procurve 4108GL Switch, I am having problems getting the fibre module communicating with a LANTECH MAX Switch III (unmanaged).

If we connect any other switch to the LANTECH this works fine, also the 10/100 module on the Procurve is working fine with the LANTECH.

On the MM-Server for the Procurve we are seeing alot of yellow alerts indicating "Exessive undersized/giant packets" when the Procurve fibre module is connected to the LANTECH Switch.

Can someone tell me what might be going on here or if someone has come across similar problem with Procurve and LANTECH MAX Switch III.

All help will be much appreciated - Thanks

Hello Jay,

What module/transceiver/G-bic in the 4100 are you connecting to what module in the Lantech switch?

Please specify with productnumber or just if it is SX/LX or LH fiber.

What kind of cable are you using? Multi- or Singlemode?

What firmware are you running on the 4100?

Kind regards,

SCOOTER

Hello Jay,

First I would advise you to upgrade the firmware on the 4100 switch to atleast the latest on the web (G.07.63).

Then my question is do you see the errors also in the eventlog of the switch?

I assume the Lantech is autosensing like the Procurve so no bother looking there.

Did the link work fine before and for how long? Or did the problems begin from the installation start? Didi you try another cable, Gbic or sport on the Procurve and on the Lantech?

If that all does not fix the problem then I would call HP support for help.

Kind regards,
