Carefully lay the blade server on a flat, static-protective
surface, with the cover side down.
Align the scalability tray flush with the blade server
in the start position. The pins on the scalability tray should be
aligned with the holes in the blade server.
Pressing down firmly on the middle of the tray, slide the
scalability tray forward toward the bezel until there is an audible
click from each side of the blade server.
Attempt to pull the scalability tray back to ensure that
the scalability tray is firmly seated.
Look in the holes on each side of the blade server to ensure
that the spring plates are engaged.
