Why does the NI Ethernet Device Configuration utility list my box as
*BUSY*
when I know my network uses DHCP?
For up to one minute, the GPIB-ENET/100 attempts to retrieve network
parameters from a DHCP server. During this time,
*BUSY*
appears in the
utility display. If this status does not change, there are several reasons why
DHCP may fail to respond. One of the most likely reasons is that your
subnet has no more available addresses to assign using DHCP. Consult your
network administrator to determine the specific reason for the problem.
I just added a GPIB-ENET/100 to the network, but it does not show up
in the NI Ethernet Device Configuration utility. What is the problem?
Allow at least 15 seconds for the GPIB-ENET/100 to complete its
power-on self tests before launching the utility or clicking Refresh.
Communication between the NI Ethernet Device Configuration utility
and the GPIB-ENET/100 is not guaranteed. Though unlikely, it is possible
that the communication gets lost in the network. Click Refresh more than
once before concluding the device is not discovered.
Verify that the GPIB-ENET/100 shares the same subnet as the computer
running the NI Ethernet Device Configuration utility. The utility cannot
communicate with devices through gateways on the network and will not
discover devices on another subnet.
I have GPIB-ENET interfaces as well as GPIB-ENET/100 interfaces.
Why can’t I see the GPIB-ENET interfaces in the NI Ethernet Device
Configuration utility?
The GPIB-ENET/100 uses a configuration protocol that can communicate
with the NI Ethernet Device Configuration utility. Because GPIB-ENET
interfaces are not compatible with this configuration protocol, the utility
does not recognize them on the network.
What do I do if the software verification test fails with an error?
Refer to the
Troubleshooting Software Problems
section of this appendix
for information about what might cause this test to fail. If you already have
completed the troubleshooting steps, contact National Instruments.
My driver is not communicating with the GPIB-ENET/100. What
should I do?
Make sure that the GPIB-ENET/100 is configured properly. Refer to
Chapter 2,
, and Chapter 4,
. Then run the
software verification utility again.
