Why is my Edimax ES-1008P V2 switch making a chirping noise?

Question

Accepted Answer

The Edimax ES-1008P V2 is a fanless switch designed to operate silently. A chirping noise should not normally occur and indicates a problem that needs to be investigated.

Possible Causes

External source: Check that the noise is not coming from adjacent equipment (fan, loose cable, other nearby network device).
Loose connections: Ensure that all Ethernet cables and the power adapter are securely plugged in at both ends.
Power issue: An unstable power supply can sometimes cause sounds. Test with another adapter if possible.
Hardware defect: Rarely, internal components may make noise if they are damaged or failing.

Steps to Try

Turn off the switch, unplug it for 30 seconds, then plug it back in.
Check that all network cables are properly connected to each port.
Inspect the power adapter - it should not make any abnormal noise itself.
Temporarily move the switch away from other equipment to isolate the source of the noise.

If the chirping persists after these checks, it is likely a hardware defect and you should contact Edimax support or your retailer to consider a warranty replacement.
