I have 4 of these switches and all lights are blinking extremely fast and in sync, even on the server nic cards. I do not have access to SSH nor the Console (UGH!). I have unplugged all 4 at the same time and plugged just one back in and it did the same thing. So I uplugged it again and plugged one other in, trying to isolate a physical loop. In doing this troubleshooting, I found that each switch does the same thing whether any other switch is plugged in. This does not make sense to me. How could each one do it if no other switches are plugged in. I ran wireshark and I do see some a couple TCP Spurious Transmissions and TCP Dup ACK. There is some broadcasts but does not look out of the ordinary as I do have a WINS server and couple xp embedded boxes that have to stay. So I do not really see a broadcast or multicast storm. I have gone around the building and did find a couple 4 port switches plugged in but verified they were not causing the loop.
I have looked in settings of the switch and my new dell laptop and our hp conference room laptop show up in the LLDP table with a TTL of around 3400, while all the uplink ports are around 90.
The only other item that is plugged into a switch is a cisco wireless controller for our two APs, which are cisco as well.
That is all i can think of to do. Anyone have any ideas??
Thank you in Advance!!!!
