Connection Error on IBM labled Brocade 300

Hi,

I have a IBM labled Brocade 300 Switch directly connected to a EMC Symmetrix fabric (Brocade port 0,1,2,3) and directly connected to 3 IBM x5 Servers (Brocade port 4,5,6). The fibre cables are plugged with its LC connector into the SFP of the switch. The SFPs are taken from the box with which the switch was coming. There are no other ones...

The problem is now: The IBM x5 server ports (Brocade port 4,5,6) show a light is coming in. But they never get a synchrionziation finished, not even started. The EMC ports (Brocade port 0,1,2,3) at the switch try to sync, show also the status "In_Sync" but never finish succesfull. Sometimes G-Port status is coming and disappearing again after few seconds.

Any ideas, suggestions? May I deliver more information about that switch, topology or settings? I enabled and disabled several times certain ports, but had no success on that...

Thanks in advance.

Hi,

     You need to post in the Data Centre forum for SAN switching.

Thanks Michael.
