Using the CFG RESET Switch during Operation
While the GPIB-ENET/100 is operational, as indicated by a steady yellow
PWR/RDY LED, you can use the CFG RESET switch to place the box into
network configuration mode. You then can use the NI Ethernet Device
Configuration utility as described in Chapter 3,
Ethernet Configuration .
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.
