I configured my Time Capsule so the LED blinks when it has activity. As I type this I notice that it is blinking constantly, even though my network is idle. The computer that uses it for backups (not the one I am on) is off, so it isn't running a backup. The cable modem uplink to the ISP is not blinking -- so the traffic isn't from outside.

I looked into the logs and don't see much that is interesting. Is there any way to find out what it is doing?

This question came from our site for system and network administrators.

From Time Capsule 802.11n (4th Generation) - Setup Guide:

If Your Time Capsule Status Light Flashes Amber


For more information about why the light is flashing, open AirPort Utility, select your Time Capsule, and then choose Manual Setup from the Base Station menu. Click Base Station Status to display information about the flashing light.

You can also select “Monitor base station for problems” in AirPort preferences. If the base station has a problem, AirPort Utility opens and walks you through solving the problem.

You could try capturing some network traffic in order to see what is going on using a tool such as Wireshark in order to do so. Try capturing data that has the source or destination IP of your Time Capsule. You'll need to make sure you're running your capture in promiscuous to ensure that you get traffic that isn't destined for your machine.
