[j-nsp] difference between "halt" and "power-off"

[Martin T]

Michel, Chuck:

It looks like "request system halt" and "request system power-off"
work differently on different platforms. With M10i for example they
both seem to do the same thing(turn routing-engine to offline) like
Chuck mentioned for EX2200/EX4200 switches. Any other
thoughts/experiences?

regards,
Martin
