# W7500S2E-R1 Orange Light Blinking

## Question

Asked by dmajb on 2020-05-21 in Serial-to-Ethernet & ConfigTool.

Hello,

The W7500S2E-R1 module I am trying to use is not currently working, and I’d like to establish a baseline of what the module’s doing so I can best determine how to proceed. My first question to anyone who’d know is, what does it mean if the orange light on the module is slowly blinking when I try to send data to it? The light comes on for about 2-3 seconds and then turns off again, only to come back on a second later and do it again. The green light on the port stays on continuously during this. Thank you very much for your help.

-Dave B.

In the RJ45 socket, orange led is data led. It may be caused by you sending or recv data, or it may be caused by other factors such as broadcast packets.
