Ethernet Configuration
Thischapter describes how to use the NI Ethernet Device Configuration
utility to configure the network parameters of the GPIB-ENET/100. You
can uset his utility for any of the following purposes:
•Manually configurethe network param eters or enable DHCP
•Verifyor change the hostname
•Add or change a comment to help identify the device
YourGPIB-ENET/100 must be in network configurationmode when you
makeany changes to the network parameters.

Entering Network Configuration Mode

IfDHCP is available on your network, it configures the network parameters
for your GPIB-ENET/100 at startup, as described in the Step 3. Switch on
YourGPIB-ENET/100 section of Chapter 2,Installation. In this case, using
the NI Ethernet Device Configuration utility is not necessary.
If the GPIB-ENET/100 is configured to use DHCP and DHCP is
unavailable,the unit automatically enters network configuration mode after
a6 0 second timeout. The GPIB-ENET/100 must be in this mode before
you can makechanges to the network parameters.
Youalso can enter network configuration mode during normal operation by
pressingand holding the CFG RESET switch for three seconds. Refer to
the Using the CFG RESET Switch section in Chapter 6, Using Your
GPIB-ENET/100 and NI-488.2 for more information on using this switch.
While in networkconfiguration mode, the PWR/RDY LED alternates
rapidly between red and yellow,and normal operation is halted.
Note If you only want to viewthe network configuration settings without ma king
changes,you do not need to place the unit into network configuration mode. While in
normal operation, you can run the utility as described in the following section, Using the
NIEthernet Device Configuration Utility, and examine the properties for any National
InstrumentsEthernet device on your subnet. However, any changes you attempt to make to
the network parameters while in normal mode will not take effect.
