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 disregards the blue LED and
thus skip the respective step. In that case, it is a purely a mechanical procedure.
1. Unlatch the lower handle by squeezing the lever and the latch together and turning
the handle outward just enough to unlatch the handle from the faceplate. Do not
rotate the handle fully outward.
The blue LED blinks indicating that the blade power-down process is ongoing.
2. Wait until the blue LED is illuminated permanently, then unlatch the upper handle
and rotate both handles fully outward.
3. Remove the faceplate cables, if applicable.
4. Rotate handle 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
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.
