We have two Procurve 2810:

1x 2810 48G
1x 2810 24G

The switches are connected through mini gbics (J9021A)

If i connect two switches together, there is no connection on the mini gbics.

The Gbics are identified and correctly installed.

If i connect the first switch to 3com switch through these mini Gbics no problem.

The problem is:

I can not connect these switches through one of the Gbics. Simply there is no link.

what is the mini GBIC you are using, the product number of it i mean.

Also for now check the fiber cable, switch the the cable (send and receive) and check

I use:

Procurve Gigabit-SX-LC Mini GBIC

Part number: 1990-3662
Product: J4858C


Kabel type:

Optronics 62 5/125 MM062

Type: LCST62D0R2

I'd also check that you have forced the port speed for the mGBIC port on both switches (int 49 speed-duplex 1000-full)

Just check 3 things (in this order)
1. May be one of the Gbics isn't plugged ok (just plug out and plug in)
2. Define both port switches to Speed Auto and MDIX Auto
3. Cross the one terminators (the lc connector) in the patch cable
4. Good Luck!!!!
