Abstract:
Methods, apparatus, and computer program products are described for resetting a HyperTransport link in a blade server, including reassigning, by a blade management module, a gate signal from enabling a transceiver to signaling a HyperTransport link reset; sending, by the blade management module to a reset sync module on an out-of-band bus, the gate signal; and in response to the gate signal, sending, by the reset sync module to the blade processor, HyperTransport reset signals. The HyperTransport link includes a bidirectional, serial/parallel, high-bandwidth, low-latency, point to point data communications link. The blade server includes the blade processor, the reset sync module, and the baseboard management controller. The blade server is installed in the blade center. The blade center includes the blade management module. The blade management module is coupled to the baseboard management controller by the blade communication bus.
