5.2.3Soft Reset

A soft reset causes the processors to begin execution in a known state without flushing caches or internal buffers. Soft resets can be generated by the keyboard controller located in the SIO, by the ICH3-S, or by the operating system.

5.3Intelligent Platform Management Buses (IPMB)

Management controllers (and sensors) communicate on the I2C-based Intelligent Platform Management Bus. A bit protocol, defined by the I2C Bus Specification, and a byte-level protocol, defined by the Intelligent Platform Management Bus Communications Protocol Specification, provide an independent interconnect for all devices operating on this I2C bus.

The IPMB extends throughout the server board and system chassis. An added layer in the protocol supports transactions between multiple servers on Inter-Chassis Management Bus (ICMB) I2C segments.

The server board provides a 3-pin IPMB connector to support add-in cards with IPMB interface.

In addition to the “public” IPMB, the BMC also has three private I2C busses. The BMC is the only master on the private busses. The following table lists all server board connections to the Sahalee BMC private I2C busses.

5.4Inter Chassis Management Bus (ICMB)

The BMC on the SE7501WV2 server board has built in support for ICMB interface. An optional ICMB card is required to use this feature because the ICMB transceivers are not provided on the server board. A 5-pin ICMB connector on the SE7501WV2 board provides the interface to the ICMB module.
