The time required for assigning the IP address depends on your network
and the configuration of your GPIB-ENET/100. Allow up to 90 seconds
and observe the state of the
PWR/RDY LED to determine the outcome of
the self tests. One of the following should occur:
• A steady yellow PWR/RDY LED indicates the GPIB-ENET/100
passed its self tests and acquired its IP address. The unit is now ready
to operate. When using DHCP, the GPIB-ENET/100 typically is
ready to operate about 15 seconds after you power it on. Run the
NI-488 Config configuration utility as described in Chapter 4, GPIB
Configuration , to add the unit to your GPIB system.
• If the PWR/RDY LED continues to alternate rapidly between red and
yellow, the unit was unable to use DHCP to configure its network
parameters. If your network does not have DHCP, you must use the
NI Ethernet Device Configuration utility, as described in Chapter 3,
Ethernet Configuration , to give your unit its network configuration.
If this utility is successful, the PWR/RDY LED should become
steady yellow. Then you can run NI-488 Config as described in
Chapter 4, GPIB Configuration . Refer to Appendix B,
Troubleshooting and Common Questions , if the LED does not change
to steady yellow.
• If the PWR/RDY LED blinks a slow red/yellow pattern, the
GPIB-ENET/100 did not pass its self tests. Refer to Appendix A,
PWR/RDY LED Signaling , to interpret the flash pattern before calling
National Instruments Technical Support.
• If the PWR/RDY LED is steady red, the GPIB-ENET/100 has an
unrecoverable error. Contact National Instruments Technical Support.
You can skip Chapter 3, Ethernet Configuration , if your GPIB-ENET/100
can use DHCP, although you do need to use the NI Ethernet Device
Configuration utility if you want to change the hostname from the default
hostname listed on the baseplate label. You also can run this utility without
entering network configuration mode if you just want to view the network
settings.
Note If at any time you want to return the GPIB-ENET/100 to its default configuration
state as given on the baseplate label, press and hold the CFG RESET switch for three
seconds while you switch the power on. This switch is located on the rear panel, as shown
in Figure 2-2. Refer to the
Using the CFG RESET Switch section in Chapter 6, Using Your
GPIB-ENET/100 and NI-488.2 , for more information.
