Unable to access the console

You are replacing an existing 3300
ICP controller with another
controller, and trying to use the
same system IP address for the
new controller from a PC on a
different subnet.
Initially, you can only connect to the
controller from the local subnet.
Before you can connect to the new
controller from other subnets, you
must manually clear the router ARP
