3-6 Setting Up Your EcoPowerGateway
Installing the outer rail
Insert the square projection of the outer rail 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.
Make sure that the rail assembly is surely locked to the rack.
