ABSTRACT:
Aspects for monitoring audible tones indicative of operational status of each planar in a multiple planar chassis are described. Included in the aspects is the monitoring of a speaker channel of each planar of a plurality of planars in a common chassis for state changes of beep tones. An operational status of a specific planar emitting the beep tones is identified based on the state changes.
