We've just acquired a 3Com 3824 24 port gigabit switch which we want to use to replace our existing 10/100 core switch.
According to the documentation it should pick up an IP from the DHCP within 2 minutes of being turned on and from then can be configured by web interface but should also work straight out of the box.
When I turn it on all I get is one light to say that power is connected. If you look in the DHCP it isn't picking up an IP (since the MAC address isn't listed) and even though I have servers and switches plugged in to it all the port lights are out.
Does anyone have any ideas?
PS. Am going to try serial link but this shouldn't be happening ... should it?
