I have added a new switch to my network and it seems that ethernet port 1 does not work on this new switch. My network consist of dhcp server>switch 1>switch 2. Switch 1 is in my entertainment center and had ethernet port 1 connected to this switch since I have had my computer but when plugged into switch 2 which I have just added to my workstation and on the switch there is no lights and in system preferences port 1 flashes between not connected and no ip address. For port 2 it connects fine and both ports are set for dhcp. I have tried different cables setting a static address and can not find a reason why it won't work. Does anybody have an idea?
