The leftmost group of digits in your IP address can identify the type of network you have. The value of this
group ranges from 1 through 127 for Class A networks (e.g., 13.27.7.1), 128 through 191 for Class B networks
(e.g.,128.10.1.30), and 192 through 255 for Class C networks (e.g., 192.168.1.4).
If you have a gateway (router), enter its address with the command SET IP ROUTER routeraddress,
where routeraddress is the desired IP address of the gateway you wish to assign to the print server. For
example:
Local> SET IP ROUTER 192.168.1.4
Type SET IP METHOD STATIC to set the method of IP access configuration to static.
To verify that you have entered the IP information correctly, type SHOW IP.
Type EXIT or Ctrl-D (i.e., hold down the control key and type "D") to end the remote console session.
