Abstract: The present disclosure relates to a cutting device with a blade moving in parallel, a moving method and a plant trimmer. By the structural device, the round blade can be adjusted to be kept in vertical rising and dropping, and is always kept in parallel to the cutting mesh. By an adjustment knob, an adjustment screw is driven to rotate by a flexible shaft, so that the movable blade holder moves up and down, which completes the adjustment of the round blade in a visible region of the equipment.

Abstract: A system for implementing a high-availability architecture comprising a first compact Peripheral Component Interconnect shelf, a second compact Peripheral Component Interconnect shelf, and a network. The first and second compact peripheral component interconnect shelf are redundant systems. The first compact peripheral component interconnect shelf comprises a first system utility card connected to a first compact core to network interface connected to a first compute platform connected to a first high speed pipe interface. The second compact peripheral component interconnect shelf comprises a second system utility card connected to a second compact core to network interface connected to a second compute platform connected to a second high speed pipe interface. The first and second compact peripheral component interconnect shelf are connected via Ethernet. The first and second compact core to network interface is connected to the network.
