Configuring the LAN IP address
Functional Description
To enable the E4980A/AL to communicate over a local area network (LAN), you 
have to configure its IP address and connect a LAN cable. The IP address can 
be either automatically obtained or manually configured. For automatic 
configuration, two methods are available: DHCP and AUTO-IP.
When the IP address is set to AUTO, DHCP address is set at first. If DHCP fails 
to obtain the address, however, AUTO-IP address is set. When the IP address is 
set to MANUAL, the address manually configured is set.
For information on the concept and implementation of automatic configuration 
by use of a LAN, see 
“LAN remote control system” on page 228.
Once you have automatically obtained an IP address, you can check the 
following monitor areas in the SYSTEM CONFIG page to see the address, 
subnet mask, and gateway: 
• CURRENT IP ADDR
• CURRENT SUBNET MASK
• CURRENT GATEWAY
Softkey Function
AUTO Automatically obtains the IP address.
MANUAL Manually configures the IP address.
Table 5-1  IP address configuration methods 
Method Description
DHCP You can automatically obtain an available IP address via a DHCP server. 
AUTO-IP You can automatically obtain an available IP address within the range 
of 169.254.xxx.xxx.
