This special mode ensures that network parameters are not changed while
in use. Because you cannot change the network parameters unless you
deliberately place the GPIB-ENET/100 into network configuration mode,
the parameters are protected while in normal operation. Hosts cannot
connect to the GPIB-ENET/100 while it is in network configuration mode.
Note
Pressing the CFG RESET switch has no effect if hosts are currently connected.
Close all connections, then press and hold the CFG RESET switch for three
seconds. If you release the switch prior to three seconds, the
GPIB-ENET/100 continues to operate normally.
The
PWR/RDY
LED 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.
3.
At three seconds, the
PWR/RDY
LED becomes steady red. This
indicates the GPIB-ENET/100 is ready to enter network configuration
mode.
4.
Now release the CFG RESET switch. The
PWR/RDY
LED alternates
rapidly between red and yellow to indicate the GPIB-ENET/100 is
now in network configuration mode.
This mode remains in effect until you switch off the GPIB-ENET/100 or
you use the NI Ethernet Device Configuration utility to change its network
characteristics. The GPIB-ENET/100 automatically reboots when you exit
the utility.
Using the CFG RESET Switch at Power-On
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.
