4.2.1.2 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
outwards.
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.
Damage of RTM and Front Blade
Removing the RTM from the system while the payload of the front blade is powered up may
damage the front blade and RTM.
Whenever removing the RTM from the system, you have to power down the payload of the
front blade first.
Data Loss
Removing the RTM with the system power on and the blue LED on the front blade still
flashing causes data loss.
Before removing the RTM from a powered system, power down the slot by opening the
lower handle of the front blade and wait until the blue LED is permanently ON.
