Resetting a Hypertransport Link in a Blade Server

apparatus for resetting a HyperTransport link in a blade server, the blade server comprising a blade processor, a reset sync module, and a baseboard management controller, the blade server installed in a blade center, the blade center comprising a blade management module, the blade management module coupled to the baseboard management controller by a blade communication bus, the HyperTransport link comprising a bidirectional, serial/parallel, high-bandwidth, low-latency, point to point data communications link,

• the apparatus comprising a computer processor, a computer memory operatively coupled to the computer processor, the computer memory having disposed within it computer program instructions capable of:
• reassigning, by the blade management module, a gate signal from enabling a transceiver to signaling a HyperTransport link reset;
• sending, by the blade management module to the 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.
