Genie 2, solid yellow status light but no errors

My Genie 2 status light turned yellow suddenly although I'm getting no error messages.  The other light on the Genie 2 and on the receiver both stay green.  I'm also not noticing any performance issues yet.

If I run the on-board system test from the menu, it comes back with no errors, and the Genie 2 status light will temporarily return to green, but will return to yellow after a short while.  Is this a problem on Directv's end or with my equipment?
