The CPE, Customer Premise Equipment, is the device that is installed in your home
for fiber installations. Some customers are connected to fiber via in-home copper wiring and will not have a CPE.
The CPE is a grey box with 3 lights located on the top panel and is located in your wire center
as seen below.
What do the 3 lights mean on top?
Top - Power
Middle - is glass
Bottom - is ethernet
What do all of the lights need to be green?
The top 2 lights (Power and Glass) should always be green. The Middle Light (Glass) should always be blinking (blink indicates activity).
The bottom light will vary depending on your internet package; if it's green, you're on the 250MBPS - 1GBPS.
If it's orange then your internet speed package is at or below 100 Mbps.
If it's not lighting up, there is no device connected to the ethernet cable.
