We have a Digi Portserver II and it is setup on a Cisco Switch. The Original Installation Manufacture set this up for us and has the Cisco switch port for this device set to 10 MB Half Duplex. The port has been blinking Orange and Green ever since installation but seems to be working(machines are running and we are getting data). The switch is showing many collisions on that port. Setting the port to auto negotiate has the same result. I can not find in the documentation what where to setup the speed nor the duplex for the device. Also I can’t find what the speed is supposed to be. Only think in the documentation I found is where it is talked about cable lengths.
The PortServer II only supports 10 MB. You can not change this. Half duplex is the recommended setting.
There may be too much traffic on that network segment.
