Removing the Blade

This section describes how to remove the blade from an AdvancedTCA system.
Damage of Circuits
Electrostatic discharge and incorrect blade installation and removal can damage circuits or
shorten their life.
Before touching the blade or electronic components, make sure that you are working in an
ESD-safe environment.
Blade Malfunctioning
Incorrect blade installation and removal can result in blade malfunctioning.
When plugging the blade in or removing it, do not press on the face plate but use the
handles.
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 lower handle by squeezing the lever and the latch together and turning
the handle outward just enough to unlatch the handle from the face plate. 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.
If the LED continues to blink, a possible reason may be that the upper layer software
rejected the blade extraction request.
