Fiber optic connection issue
Our main switch is a HP Procurve 4108GL - We have recently had a new fiber optic run from the main switch over to a new switch/cab in the music area. Connecting the main switch to music is an OM3 patch cable which comes out of an SC port (J4131A) and into a new LC patch panel.
The switch the other end is an HP 2910-48 with a HP J4858C GBIC module (SX-LC) inserted. The cable comes out of the fiber patch panel in music and into the HP GBIC module. Again this patch cable is OM3 (LC-LC).
For some reason is just won't connect! I've checked and confirmed all of the ports both ends are working, so I just can't figure out what's wrong!
