Abstract: A system chassis includes a bottom panel, a first sidewall, and a second sidewall. The bottom panel defines a width of the system chassis. The first sidewall extends substantially vertically from a first end of the bottom panel. The first sidewall includes a first channel vertically offset from the bottom panel. The first channel is configured to mate with a first rail of an equipment rack. The second sidewall extends substantially vertically from a second end of the bottom panel, and is opposite to the first sidewall. The second sidewall includes a second channel configured to mate with an opposing rail of the equipment rack.

Abstract: A system is disclosed that includes a bay within a computer system, such as a fan bay. The system further includes a baffle positioned around a section of a perimeter of the bay. The baffle is configured to move along the section. The baffle includes a projection that extends into the bay. The projection is configured to abut against a module, such as a fan module, so that the module drives the baffle from a closed position to an open position as the module is inserted into the bay.

Abstract: Described herein is a server that includes a server chassis having a front window for providing access to an interior receptacle of the server chassis. A docking station is located in the interior receptacle. The server also includes a PCIe module coupled to the docking station by a coupling element. The PCIe module protrudes externally from the interior receptacle through the front window in the docked position. The PCIe module can be moved to a plurality of undocked positions while remaining coupled to the docking station.

Abstract: A computer chassis includes a first ha frame having a first opening and a second bay frame disposed adjacent to the first bay frame. The second bay frame has a second opening of a same size as the first opening. The first bay frame and the second bay frame a both configured to receive one of a first adapter cage and a second adapter cage. The first adapter cage is for one or more first removable devices of a first form factor and the second adapter cage is for a plurality of second removable devices of a second form factor. The second form factor is different from the first form factor.

Abstract: A drive (e.g., hard drive) carrier can have a frame with a door that can open to permit installation of the drive and can snap shut to secure the drive within the drive carrier. The drive carrier can include a connector lock, which can take the form of a pair of pins extending from the frame and capable of engaging corresponding retention holes of a connector of a cable. The connector lock can help align the cable's connector with the drive's connector, as well as releasably lock the cable's connector in place when operatively connected to the drive. Damping couplings can couple the carrier frame to a computer chassis. The damping couplings and the flexibility of the cable vibrationally isolate the drive from the chassis, while the connector lock ensures the cable's connector does not unintentionally disconnect from the drive.

Abstract: The disclosure provides a system and method for an external processor to access internal register. The internal register may be a register of a core networking device. The method includes: sending, by an external processor, a read request to a core networking device; responding, by the core networking device, to the read request; sending, by the external processor, a write request to the core networking device; and preparing, by the core networking device, a register status notification of a register embedded in the core networking device and sends the register status notification to the external processor in response to the write request. The read and write requests and the responses are in a layer 2 protocol (L2 protocol).

Abstract: The disclosure provides a method for transmitting a physical layer operation administration and maintenance (PLOAM) message over an Ethernet network. The method includes the steps of: transmitting, from a first terminal, the PLOAM message to a second terminal over a PLOAM channel connecting the first and second terminals; extracting, by the second terminal, the PLOAM message; sending, from the second terminal, the extracted PLOAM message to an external CPU over an Ethernet protocol; and processing, by the external CPU, the received PLOAM message to generate a processed PLOAM message.

Abstract: Various powered personal mobility vehicles are disclosed. In some embodiments, the vehicle can include a deck having a forward portion, a rearward portion, and a neck portion. A front swivel wheel assembly and a rear swivel wheel assembly can be connected with the deck. In some embodiments, the front swivel wheel assembly comprises a motor.

Abstract: A kart having a pedal speed controller and other components and arrangements thereof are disclosed. The kart can be provided with a controller for controlling speed; the pedal speed controller comprising a pedestal and a pedal, one end of the pedal is articulated with the pedestal and keeps a certain angle with the pedestal. The pedal speed controller also comprises a sensor connected with the controller, and the sensor can obtain displacement signal along the tread direction of the pedal. The pedal speed controller has the advantages of realizing pedal control of acceleration or deceleration for drivers, avoiding interference with manual adjustment of kart direction, preventing from mutual influence between speed regulation and steering, improving the speed control performance of the kart, and improving the driving experience.
