By default, the GPIB-ENET/100 attempts its network configuration
automatically through DHCP. 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.
• If the PWR/RDY LED continues to flicker orange rapidly, the unit
was unable to use DHCP to configure its network parameters. It is now
in network configuration mode. Refer to
information on configuring the network parameters manually. If this
utility is successful, the PWR/RDY LED should become 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
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.
Table 1-1 summarizes the functionality of all the front-panel LEDs on the
GPIB-ENET/100.
Table 1-1. GPIB-ENET/100 LED Descriptions
Flashes orange rapidly at startup while performing self tests and when
acquiring network parameters. A steady yellow state indicates the box
is ready for operation. A distinct red/yellow flashing pattern indicates
an error occurred.
Indicates the GPIB-ENET/100 detected a twisted pair (10Base-T or
100Base-TX) link. The color indicates the connection speed. If yellow,
the speed is 10 Mbits/s. If green, the speed is 100 Mbits/s.
Indicates the GPIB-ENET/100 is transmitting to the Ethernet network.
Indicates the GPIB-ENET/100 is receiving Ethernet network traffic.
Indicates the GPIB-ENET/100 is configured as a GPIB Talker.
Indicates the GPIB-ENET/100 is configured as a GPIB Listener.
