First post, so please be gentle...
We are planning to change the current infrastructure of one of our clients.
As part of this process we are replacing “RJ45 to Optic Fibre converters” with “Cisco mini-GBICs”.
In the attached PDF file you will see 2 examples.
Example 1 represents the current client setup
In Example 2 we have replaced the branch office “RJ45 to Optic Fibre converter” with a Cisco MGBSX1 connected to the Cisco SG300
However this does not work, the Cisco SG300 never boots up correctly and after connecting the Fibre to the Mini-GBIC, the Cisco switch System LED just keeps flashing.
I suspect for this to work we also need a Mini-GBIC connected to the HP Procurve2510 replacing the “RJ45 to Optic Fibre converter” in the Main office!
Is anyone able to confirm this?
If this is not the problem, what else could we be doing wrong?
