Power-Up Reset Mode
Figure 8 - Status LEDs
During the Power-Up Reset mode, the following procedure occurs.
1. The various status indicators (LEDs) cycle simultaneously.
• Module Status (MS) status indicator flashes green for approximately
0.25 seconds, flash red for another 0.25 seconds, then remain a solid
green.
• EtherNet/IP Network Status (NS) status indicator flashes green for
approximately 0.25 seconds, flash red for another 0.25 seconds, then
not illuminate.
• Device Network Status (NS) status indicator flashes green for
approximately 0.25 seconds, flashes red for another 0.25 seconds,
then does not illuminate.
The MS and both NS status indicators then return to their standard
illuminated state.
2. The EtherNet/IP communication auxiliary module performs 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 status indicator illuminates to a solid red,
the MS status indicator flashes red, and the EtherNet/IP
communication auxiliary module enters the Recoverable Error mode.
