Each module is inserted into the 4 U subrack from the front and is secured
at the front with a metal clamp. Both clamp and module are easily removed
for rapid module replacement. The modules are secured laterally with plastic
guides that clip into the top and bottom of the subrack. These guides can be
easily repositioned to change the configuration of a subrack. The heavier
modules are also secured laterally by metal tabs at the rear of the subrack.
