Chapter 4 Feature Set Description

Appendix C, Troubleshooting, for more information about STATUS
LED error indications.
LINK LED
The green LINK LED is lit when the FP-20xx is connected to a functioning
Ethernet segment.
ACTIVE LED
The green ACTIVE LED is lit when the FP-20xx receives data from or
transmits to the Ethernet. Because of unrelated network activity, this LED
blinks occasionally even when the FP-20xx is inactive.
100 Mbps LED
The yellow 100 Mbps LED is lit when the FP-20xx is communicating at
100 megabits per second. If the 100 Mbps LED does not light, all
communications with the FP-20xx will be at 10 megabits per second.
User-Configurable LEDs A–D (for Count-Output Channels 5–8)
LEDs A, B, C,andD correspond to count-output channels 5, 6, 7, and 8,
respectively, on the network module. LEDs B, C,andD can be sent values
of 0, 1, or 2. LED A should be sent only 0 or 1. LED A handles a 2 as a 1.
The values sent to these LEDs manifest as 0 = off, 1 = green, and 2 = red.
Power-On Self Test (POST)
The FP-20xx runs a power-on self test (POST) at power-up to verify its
own operational status. The test takes several seconds, does not affect the
operation of the network, and does not affect any of the field wiring
connected to the terminal bases in the bank.
If the power-on self test fails, the FP-20xx does not participate in network
communication, eliminating potential conflicts with the other banks in the
network.
When you power up the FP-20xx and it has already been configured for use,
the POWER and STATUS LEDs come on for about five seconds, then the
STATUS LED turns off. The A, B, C,andD LEDs come on for about
15 seconds as LabVIEW RT starts up. When they turn off, the I/O module
READY LEDs turn on and the network module is ready for use.
The FP-20xx indicates POST failure through the STATUS LED. If the
LEDs do not follow the sequence described here, refer to the STATUS LED
