EtherNet/IP Option LEDs
The EtherNet/IP Option has two bi-color, red/green LEDs: one for Module Status (MS) and one for Network Status (NS)
and two green Ethernet LEDs: one to indicate network speed (10/100) and one to indicate the link status and network
activity (LINK/ACT).
The operational states of the EtherNet/IP Option LEDs after the EtherNet/IP power-up diagnostic LED sequence is
completed are described in
Table 4 . Wait at least 2 seconds for the power-up diagnostic process to complete before
verifying the states of the LEDs.

Power-Up Diagnostics
An LED test is performed each time the drive is powered up. The initial boot sequence may take several seconds. After
the LEDs have completed the EtherNet/IP diagnostic LED sequence, the EtherNet/IP Option is successfully initialized.
The LEDs then assume operational conditions as shown in
Table 4 .
