Abstract: Systems and methods related to serial communication devices are provided. An example integrated circuit (IC) device includes interface circuitry coupled to a two-wire serial communication bus having a serial clock (SCL) line and a serial data (SDA) bus line. The IC device further includes bus stuck recovery circuitry to monitor for a local SDA fault condition at the IC device based on a number of clock cycles during which an internal SDA signal (e.g., generated by the IC device) drives the SDA bus line to a first signal state, the clock cycles based on a clock signal received from the SCL line; and responsive to the local SDA fault condition, release the SDA bus line independent of the internal SDA signal, where the SDA bus line is in a second signal state different from the first signal state based on the release.

Abstract: A computer for a server or work station which has two air cooling streams one stream leads from outside the chassis across the motherboard and through a vented power supply then directly into the environment and is driven by a fan inside the power supply. This air stream independently and directly removes the major source of heat which is the power supply. The second air stream circulates from outside the chassis through the hard drives and out of openings adjacent the hard drives and is driven by fans positioned between the hard drives and vented openings in the chassis. The efficient heat removal is compatible with an arrangement of components in the chassis such that the overall height is less than 3½. The reduced height and efficient heat removal make the computer ideally suited for mounting in a server chassis with other servers where close spacing is desired.
