Removal Procedure
The following procedure describes how to remove the blade from a system. It assumes that the
system is powered on. If the system is not powered on, you can disregard the blue LED and skip
the respective step. In that case, it is purely a mechanical procedure.
1. Unlatch the handle from the face plate by sliding the latch into the release position
and pull out the handle outward. Do not rotate the handle fully outward. The blue
LED blinks indicating that the blade power-down process is ongoing.
The blue LED blinks indicating that the blade power-down process is going on.
2. Wait until the blue LED is illuminated permanently. Unfasten the screws of the
faceplate, then unlatch the handle and rotate the handle fully outward until the
blade is detached from the shelf.
3. Remove the face plate cables, if applicable.
4. Unfasten the screws of the face plate until the blade is detached from the shelf.
5. Remove the blade from the shelf.
If the LED continues to blink, a possible reason may be that the upper layer software has
rejected the blade extraction request.
Data Loss
Removing the blade with the blue LED still blinking causes data loss.
Wait until the blue LED is permanently illuminated, before removing the blade.
