Insert Cage Nuts Into Rail Holes
Because the RETMA rails have square holes, you might need to
use cage nuts to secure the equipment into the rack. The rack
ship kit contains extra M6 cage nuts and M6 screws. If possible,
use the cage nuts that shipped with the equipment's rackmounting
Using your equipment's rack alignment template, or other
equipment documentation, locate the rail holes you are using
to install the equipment.
Use the cage nut insertion tool in the ship kit to
install the cage nuts in the rails.
Align the cage nut with the square rail hole .
Hook the side lip of the nut in the square rail hole
Insert the tip of the cage nut insertion tool through the
rail hole, hook the other side lip of the cage nut, and
lever the cage nut into place .
