A fan system for improved external case fan design with self-cleaning bristles, the fan system includes a housing a housing defining an opening and an interior space that extends along an axis, a plurality of fan blades positioned within the interior space and configured to rotate about the axis, and bristles positioned proximate to the opening of the housing. The fan system also includes one or more brushes configured to rotate about the axis and to be moved to a position to engage the bristles for cleaning and a mechanism configured to move the brushes to the position for engaging the bristles.

A computer-implemented method includes: connecting, by a network device, with a user device via an alternate communications network; and providing, by the network device to the user device and via the alternate communications network, network credentials used for wireless access to a primary communications network, wherein the primary communications network and the alternate communications network are different.

Network credentials for wirelessly accessing a LAN via an alternate communications network

At initiation of boot of a computing device, a processor executes a firmware interface of the computing device, like a basic input/output system (BIOS) or a unified extended firmware interface (UEFI). The processor executes the firmware interface to detect whether a dynamic hardware configuration (DHC) function has been enabled. In response to detecting that the DHC function has been enabled, the processor executes the firmware interface to configure hardware components of the computing device according to a DHC, such as to selectively disable the hardware components. After configuring the hardware components according to the DHC, the processor proceeds to boot the computing device.

A method includes running a system mainline initialization process on a compute node that includes an expansion card with read-only memory storing expansion card initialization code. The method obtains and executes the expansion card initialization code from the read-only memory to perform initialization of the expansion card. The method further includes updating a current operational progress state of the expansion card initialization stored in non-volatile memory of the node as the expansion card initialization moves through a plurality of operational progress states, detecting a fault, such as a hung condition, during the expansion card initialization in response to exceeding a predetermined time period in the current operational progress state, and storing a fault indication in the non-volatile memory, wherein the fault indication identifies the card experiencing the fault. Optionally, the method may reset the node and bypass initializing the card associated with the fault indication.
