Removal Procedure
The following procedure describes how to remove the blade from a shelf. 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 steps. In that case, it is purely a mechanical procedure.
1. Unlatch the handle from the faceplate by sliding the latch into the release position
and pull out the handle outward. Do not rotate the handle fully outward. The blue
LED starts blinking indicates that the blade power-down process is ongoing.
2. Wait until the blue LED is illuminated permanently. Loosen 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 faceplate cables, if applicable.
4. Loosen the screws of the faceplate 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.
