This is necessary so that the OS of the front blade can recognize the SAS controller
or any other PCI device located on the RTM.
2.3.2 Removing the RTM
Removal Procedure
The following procedure describes the removal of the RTM. It assumes that your system is
powered. If your system is unpowered, you can disregard the blue LED and thus skip the
respective step. In this case it is a purely mechanical procedure.
1. Unlatch the lower handle outward by squeezing the lever and the latch together
and turning the handle outward only enough to unlatch the handle from the face
plate, that means until you feel a resistance. Do not rotate the handle fully outward.
The blue LED blinks indicating that the shelf manager is informed about the desire
of the blade to power down the payload of both the front blade and the RTM and
the power-down process is ongoing.
2. Wait until the blue LED of the RTM is permanently ON.
