A network device may comprise an auxiliary processor to conserve the power of the network device. An hydraulic coupler includes a master piston, a slave piston, and a coupler volume formed in-between, the coupler volume being connected to a compensating chamber via a throttle. The visor assembly and the head cover assembly on one hand, and the suspension system on the other, are separable and foldable to enable storing andor shipping the same separately. The combined NFET active area for the planar pass gate NFET and the planar pull-down NFET is substantially rectangular, which enables a high fidelity printing of the image of the combined NFET active area by lithographic means.
