Power-Up Reset Mode
Figure 8 - Status LEDs
During the Power-Up Reset Mode, the following procedure occurs.
1. The various LEDs will cycle simultaneously.
• Module Status (MS) LED will flash green for approximately 0.25
seconds, flash red for another 0.25 seconds, then remain a solid green.
• EtherNet/IP Network Status (NS) LED will flash green for
approximately 0.25 seconds, flash red for another 0.25 seconds, then
not illuminate.
• Device Network Status (NS) LED will flash green for approximately
.25 seconds, flash red for another0 .25 seconds, then not illuminate.
The MS and both NS LEDs will then return to their standard illuminated
state.
2. The EtherNet/IP Communications Auxiliary will perform a duplicate IP
address check to verify that another module is not assigned to the same IP
address. If a duplicate IP address is detected on the network, the EtherNet/
IP NS LED illuminates to a solid red, the MS LED flashes red, and the
EtherNet/IP Communications Auxiliary enters the Recoverable Error
Mode.
3. The EtherNet/IP Communications Auxiliary performs a duplicate MAC
address check to verify that another module is not assigned to the same
MAC address. If a duplicate MAC address is detected on the DeviceNet
network, the DeviceNet NS LED illuminates a solid red, the MS LED
flashes red, and the EtherNet/IP Communications Auxiliary enters the
Recoverable Error Mode.
