When you have computed your error message number, write it down and
also note the ON/OFF state of the
LINK , TX , and RX LEDs. Have this
information available when calling National Instruments.
CFG RESET Switch
The Configuration Reset ( CFG RESET ) switch is a recessed switch
located beside the ENET connector on the rear panel.
You can use this switch to either reset the unit to its default network
characteristics or place the GPIB-ENET/100 in network configuration
mode.
Reset the Default Network Characteristics at Startup
If you want to reset the unit to its default network characteristics, you can
use the
CFG RESET switch at power-on. By pressing and holding the
CFG RESET switch while you power on the GPIB-ENET/100, the
network parameters revert to the default settings as defined on the baseplate
label.
You must press and hold the switch for three seconds. If you release
the switch prior to three seconds, no change occurs to the network
configuration, and the GPIB-ENET/100 continues to boot normally.
Observe the PWR/RDY LED as it goes through the following changes
during these three seconds.
1. The LED begins slowly alternating between red and yellow.
2. The alternating pattern increases in tempo.
