PWR/RDY LED Signaling
PWR/RDY LED Overview
Note By recording the PWR/RDY LED error messages before calling National
Instruments, you can save yourself time, and customer support can answer your questions
more accurately and efficiently. Do not switch off power to your serial device server before
recording the flashing PWR/RDY LED pattern.
There is no zero in any error message. This means that error message numbers 0–10,
Note
20, 30, 40, 50, 60, 70, 80, and 90 are not possible.

This appendix describes how to interpret the PWR/RDY LED error codes.
The PWR/RDY LED has several purposes on the serial device servers.
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.
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.
