Hardware Preparation and Installation
Removal Procedure
The following procedure describes how to remove the blade from a system. It assumes that the
system is powered. If the system is unpowered, you can disregards the blue LED and thus skip
the respective step. In that case it is a purely mechanical procedure.
1. Unlatch the lower handle by squeezing the lever and the latch together and turning
the handle outward only 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.
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.
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 upper layer software rejects the
blade extraction request.
3. Remove face plate cables, if applicable.
4. Unfasten the screws of face plate until the blade is detached from shelf.
5. Remove the blade from the shelf.
2.7 AMC Modules
The blade provides two AMC bays: AMC B4 and AMC B1. Their location is shown in the
following figure.
