1. An assembly for ejecting a line module from an equipment bay of a chassis of a networking device, wherein the chassis has a back and a front opposite the back having a chassis opening configured to receive the line module into the equipment bay of the chassis, wherein the line module is configured to be installed within the equipment bay of the chassis of the networking device, the line module having a front panel, the front panel having an exterior surface, an interior surface, a first side, and a second side opposite the first side, the assembly comprising:
an ejector block having an interior portion connected to the interior surface of the front panel and positioned proximate to the second side of the front panel, and having an exterior portion positioned outside of the equipment bay and proximate to the front of the chassis when the line module is installed in the equipment bay of the chassis, the ejector block movable between a neutral position and an ejecting position, the ejector block configured to apply a force to the front of the chassis in a first direction toward the back of the chassis when the ejector block is moved into the ejecting position and contacts the front of the chassis, thereby moving the line module in a second direction away from the back of the chassis;
one or more guide pins connected to the ejector block and configured to guide movement of the ejector block between the neutral position and the ejecting position;
a mounting bracket having a first end attached to the interior surface of the front panel of the line module proximate to the second side of the front panel, the mounting bracket having a second end extending away from the interior surface of the front panel and having a bracket opening;
an ejector lever having a handle end, a pivot portion, and a load end, the load end positioned proximate to the exterior portion of the ejector block, the pivot portion having a pivot opening positioned proximate to the bracket opening of the second end of the mounting bracket; and
a fastener positioned through the bracket opening of the second end of the mounting bracket and the pivot opening of the pivot portion of the ejector lever such that the ejector lever is pivotable about the fastener between a closed position in which the handle end is proximate to the exterior surface of the front panel of the line module and an open position in which the handle end is distanced from the exterior surface of the front panel of the line module and the load end has contacted and moved the ejector block into the ejecting position.
