CobraNet Indicators

Check for proper operation of a CobraNet® device by checking the following indicators:

• Check the power indicator to ensure that the device is receiving the proper power supply. Power indicators can vary by specific product.
• Check indicator lights on the connected switches to make sure a good link exists and that the data rate is at least 100 Megabits. For a description of switch indicators, refer to the manual provided by your switch manufacturer.
• Check the RJ-45 connection indicator lights for your CobraNet interface device as detailed below. Please note: if your device has two RJ-45 connections (the most common case), the lights for each connection will behave identically.
