We have a new device by Raritan it is a Dominion SX16. It has an ethernet connection. With a straight thru cable plugged into its ethernet port.
When we plug the other side of the ethernet cable into a 6500 Cisco Switch we (do not) get a link light on the Cisco port and Raritan device. The port is just configured for 100/full and on VLAN 1
When we plug the other side of the ethernet cable into a 2924 or 2912 switch we (do) get a link light on both devices ports. The port is also just configured for 100/full and on VLAN 1
What is the problem, there should be no difference between an ethernet port on a 6500 switch and a port on a 2900 switch? We have tried to connect this device to multiple 6000 switches and we get the same result no connection and no link lights but everytime we connect to a2900 switch port we get a connection.
I have been doing networking for over 7 years and I have never seen this type of problem.
Any help is appreciated????
