Abstract
In one example embodiment, a host device includes a front panel, a bezel assembly, a floating PCB, and two host guides. The front panel defines an opening configured to receive a pluggable module in a plugging direction. The bezel assembly defines an opening configured to align with the front panel opening and to receive the pluggable module, the bezel assembly rigidly secured to the front panel. The host guides are rigidly secured to the floating PCB and are configured to guide the pluggable module when it is plugged into the host device. The host guides and bezel assembly operate together to allow the floating PCB to float with respect to the front panel in the plugging direction while remaining substantially aligned with the front panel in directions normal to the plugging direction.
Claims16
A host device for receiving a pluggable electronic or optoelectronic module, comprising:
- a front panel defining an opening configured to receive a pluggable module in a plugging direction;
- a bezel assembly defining an opening configured to align with the front panel opening and to receive the pluggable module, the bezel assembly rigidly secured to the front panel;
- a floating printed circuit board disposed behind the front panel;
- and
- a first host guide and a second host guide rigidly secured to the floating printed circuit board and configured to guide the pluggable module when plugged into the host device, the first and second host guides and the bezel assembly operating together to allow the floating printed circuit board to float with respect to the front panel in the plugging direction while remaining substantially aligned with the front panel in directions normal to the plugging direction.
A host device for receiving a pluggable optoelectronic module, comprising:
- a front bezel including a first front bezel guide and a second front bezel guide, each of the first and second front bezel guides including a guide channel configured to receive a first or second guiderail of a pluggable module inserted through the front bezel in a plugging direction;
- a rear bezel rigidly secured to the front bezel, the front and rear bezel forming a first opening configured to receive the pluggable module;
- a front panel rigidly secured between the front bezel and the rear bezel, the front panel defining a second opening aligned with the first opening;
- a printed circuit board configured to float in the plugging direction with respect to the front panel;
- and
- a first host guide and a second host guide rigidly secured to the printed circuit board, the first host guide defining a first channel and the second host guide defining a second channel, the first and second channels configured to receive the first and second guiderails of the pluggable module;
- wherein the first and second host guides and rear bezel operate together to allow the printed circuit board to float with respect to the front panel in the plugging direction while remaining substantially aligned with the front panel in directions normal to the plugging direction.
