I have an old Dell 6224 switch that was being used in an offsite co-location. We now no longer use it for that. I am trying to reset it back to the factory defaults (option 10) and it appears to be working until I go into setup to set up an IP address. Instead of assigning an IP, I am entering DHCP as instructed. The switch is not picking up an address from my DHCP server. If I plug a PC into that cable, it picks up DHCP just fine but if I plug the cable into port 1 of the switch, it gets nothing. If I plug the PC into the switch, it gets nothing.
