Apparatus for mating a field-replaceable unit to a backplane of a telecommunications system

A field-replaceable unit comprising:

• a communications circuit that facilitates communication among computing devices within a network;
• at least one connector that facilitates communicatively coupling the communications circuit to a backplane of a telecommunications system;
• and
• at least one helical ejector that comprises:
• a shaft;
• a tightening knob coupled to the shaft;
• a spring that envelops the shaft;
• a nut that:
• is coupled to the shaft;
• abuts the tightening knob;
• and
• abuts the spring;
• and
• an ejector block;
• wherein:
• the helical ejector fastens to a housing of the telecommunications system to enable the connector to communicatively couple the communications circuit to the backplane of the telecommunications system;
• and
• the tightening knob compresses the spring against the ejector block by way of the nut such that the spring applies a force on the field-replaceable unit that pushes the connector toward the backplane of the telecommunications system.
