When the blade is completely installed, the blue LED starts to blink. This indicates
that the blade announces its presence to the shelf management controller.

The switched off blue LED indicates that the blade’s payload has been powered up
and that the blade is active.
7. Connect cables to the faceplate, if applicable.

the front blade are closed in order to power up the blade’s payload.

ESD-safe environment.
Blade Malfunctioning
