PWR/RDY LED Signaling
This appendix describes how to interpret the PWR/RDY LED error codes.
PWR/RDY LED Overview
The PWR/RDY LED has several purposes on the GPIB-ENET/100.
When you first power on the unit, the PWR/RDY LED alternates rapidly
between red and yellow while it completes its power-on self-tests and
acquires network parameters. When the tests complete successfully and
the IP address is assigned from either nonvolatile memory or the network,
the PWR/RDY LED remains steady yellow, indicating that the unit is
ready to operate.
The PWR/RDY LED also alternates rapidly between red and yellow
while the device is in network configuration mode. At other times, the
PWR/RDY LED blinks slowly in a recognizable pattern to alert you of
internal errors. Use this appendix to interpret and record the pattern that
the PWR/RDY LED flashes, and then contact National Instruments.
Note By recording the PWR/RDY LED status messages before calling National
Instruments, you can save yourself time, and the Product Support Department can
answer your questions more accurately and efficiently. Do not switch off power to
your GPIB-ENET/100 before recording the flashing PWR/RDY LED pattern.
PWR/RDY LED signaling can report up to 81 different errors. The errors
are numbered from 11 to 99 and are reported through sequences of
PWR/RDY LED flashes.
Note There is no zero in any error message. This means that error message numbers 0–10,
20, 30, 40, 50, 60, 70, 80, and 90 are not possible.
