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 serial device server is ready to enter networkconfiguration mode.4. Now release the CFG RESET switch. The PWR/RDY LED alternatesrapidly between red and yellow to indicate the serial device server isnow in network configuration mode.This mode remains in effect until you switch off the serial device serveror you use NI Ethernet device configuration to change its networkcharacteristics.Using the CFG RESET Switch at Power-OnIn the event you forget the network configuration that a particular serialdevice server is using, you can reset the unit to its default networkcharacteristics. By pressing and holding the CFG RESET switch while youpower on the serial device server, the network parameters revert to thedefault settings as defined on the baseplate label.You must press and hold the switch for approximately three seconds untilthe PWR/RDY LED becomes solid red. If you release the switch prior tothree seconds, no change occurs to the network configuration, and the serialdevice server continues to boot normally.The PWR/RDY LED goes through the following changes during thesethree 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.
