How do you check/verify knox status?

view story

http://forum.xda-developers.com – I have a N900 and was wondering how you check your knox status? I tried going into download mode, but there I only see a similar download screen like note 2: ODIN MODE PRODUCT NAME: SM-N900 CURRENT BINARY: Samsung Official SYSTEM STATUS: Official I don't see a knox flag. Does it show up only when it's been tripped? (HowTos)
