Hi there.
Im having a recurrent issue on a network with a main SG102-24-NA switch and secondary TEG-S80g switches.
This is very strange:
I have 3 of these TEG-S80g switches distributing the network to PCs and printers. 2 of them work just fine (one connects to a xerox 7665 and 2 desktop PCs, and the other to 3 desktop PCs), but one on them is droping connection consinuously, y have changed that switch 2 times and tripple checked my cabling (cat6a with shielded connectors) with no luck. That particular swith connects to a konica minolta c550, a kyocera 5030 and a desktop PC, in wich i have changed the network card 2 times by now)
Im starting to believe that some of the network cards from the printers are causing this issue.
What do you think guys?
Note: Im routing in DHCP with a Zentyal Server, 10.0.0.0/24 (2-250) IP address range.
