[j-nsp] QFX5100 red alarm after power-off

[Luis Balbinot]

Ask your SE, it might be faster.

But sometimes the piece of software that actually control those LEDs
(and the whole chassis) runs on the OS that you have just powered off.
Maybe the red LED means that there's no chassis mgmt at all. That's
why we get extremely loud fans on power up and they calm down as soon
as the chassis mgmt process kicks in.
