Installing rail assemblies
Insert the square projection of the rail assembly with the marking "F" facing front into the angle
hole on the 19-inch rack until it is locked with clicking sound.
The figure below shows the right side (front) of the rack. Install the rail assemblies to the right side
(rear), and left side (front and rear) of the rack in the same procedure.
Make sure that the rail assembly is installed at the same level as the other slide rail assembly already
installed.
NOTES:
There may be some backlashes in the front and rear, however, it is
not a deficiency.
When inner rails are installed on both sides, adjust the position of
cooling kit properly, then install the rail assembly to the rack.
Make sure that the rail assembly is surely locked to the rack.
