SRW2048 Fiber Run to HP ProCurve 2524 via MGBSX1 Not functioning

Unanswered Question
Aug 4th, 2010

All,

I have a customer with a single Cisco SRW2048 switch that has been installed at the network core and is due to replace two aging HP ProCurve 2524 Switches. Previously, the HP Procurves were linked via Fiber to similar HP ProCurve 2524's in a network closet on the opposite side of the building. The Fiber running through the walls is terminated on both sides with a generic / fully functional Fiber switch that use ST Connectors to output the fiber.

On both ends, currently, a ST -> SC MultiMode Fiber is connected from the fiber switch to a HP ProCurve 100-FX SC Transceiver (J4853A: http://h10010.www1.hp.com/wwpc/ie/en/sm/WF06c/A1-329290-64274-64484-64484-51105-22212.html). This setup works 100% right now, however, they do not want to keep the old switch around (inside the core) simply to act as a transceiver for the fiber run.

They purchased a MGBSX1 and a ST -> LC MMF cable and can not seem to get it functional. I saw this thread: http://homecommunity.cisco.com/t5/Switches/connecting-two-SRW2048-switches-over-multimode-fiber/m-p/270381 and attempted shutting off auto negociation (locking it down at 100MB) and it did not bring the interface up (Interface is always down).

I just saw this thread tonight: https://supportforums.cisco.com/thread/2012252 Can anyone confirm that the MGBSX1 can not clock down to 100MB to pair with the 100-FX transciever they have?

If it CAN, has anyone done such a project before / can give me some insight on this matter?

Thanks in advance!

I have this problem too.

Hi Jonathan,

The MGBSX1  will not clock at 100FX speeds sorry, and I'm guessing that if you want to run 100FX the distances between the switches are larger than 200meters.

The MFEFX1 (100FX)  or MFELX1  (100LX)  modules are not any help to you they support the following products;

Compadability for MFEFX1 and MFELX1
Switch   Model Number MFEBX1/MFEFX1/MFELX1

* SFP port requires   manual configuration for the 100M SFP  .

But I have attached the install guide for the 100meg fiber  modules as a refererence.

My apologies for this situation, please unicast me with contact details.
