Set/display IP address

Although normally done from within the the Manager program, you can also display or change the IP adresss of either LAN port via the RS232 (DTE) Maintenance port on the back of the IP Office. They may be instances where this is useful.

Enter the following commands (in bold) when the IPOffice is up and running:

Enter IP address (a.b.c.d):

Enter IP mask (a.b.c.d):

Add default gateway (yes or no)?

Ipaddr    = c0a82a01 ffffff00 2 200         LAN port address and subnet-mask in HEX
Ipaddr2   = 804b0064  ffffff00 2 1            WAN port address and subnet-mask in HEX
S/W Build = IP 500 V2 8.1(63)

Enter the HEX values into the Hex IP-address converter above to find the dotted decimal values.
In this example, Ipaddr (LAN) is, Ipaddr2 (WAN) is, and the subnet-mask is
