CHS 435HDC error code Er:21

Tried resetting the modem and cable box but the box will not turn on. It keeps displaying Er:21 error code. I believe the box is dead but Does anyone know what that error code is?
Thanks, CT

That worked! Amazing that was the issue. I am wondering if they did a firmware update and that screwed with it because it looks like some things were updated with the Fios box. Anyway thank you very much for the help!
