A computer system comprises host processor and a network interface, wherein the host processor includes resources supporting a full power mode, a lower power mode and a power down mode, as seen in standard system bus specifications such as PCI and InfiniBand. The network interface includes a medium interface unit coupled to network media supporting a least high speed protocol, such as a Gigabit Ethernet or high-speed InfiniBand, and a lower speed protocol, such as one of 10 Mb and 100 Mb Ethernet or a lower speed InfiniBand. Power management circuitry forces the medium interface unit to the lower speed protocol in response to an event signaling entry of the lower power mode. In the lower power mode, the network interface consumes less than the specified power when executing the lower speed protocol, and consumes greater than the specified power when executing the high speed protocol. Logic in the network interface operates in the lower power mode, and uses the lower speed protocol to detect a pattern in incoming packets. In response to the detection of said pattern, the logic issues a reset signal to the host processor. Thus, the network interface operates as a wake-up device in the lower power mode, using the lower speed protocol.

In this way, great stress raised by great temperature gradient on the CPU's surface can be avoided and CPU's physical damage can also be avoided.

The invention discloses a method for reducing the production of preoxidized broken filament during the preparation of polyacrylonitrile-based carbon fiber, characterized in that: dipping: polyacrylonitrile-based carbon fiber precursor is dipped with pure water until the water content in the precursor is 5-15wt%; or polyacrylonitrile-based carbon fiber precursor is dipped with epoxy ethane modified silicone oil emulsion or ammonia modified silicone oil emulsion until the water content in the precursor is 5-15wt% and attached amount of oil is 0.5-1wt%; and shaping: the dipped precursor is subject to shaping. Owing to the effect of surface tension of the pure water, a fiber bundle dipped with the pure water is increased in convergence property, and the generated broken filaments are adhered to the fiber bundle; a layer of protective film is formed on the surface of fiber by using the fiber bundle dipped with the oil emulsion, thereby preventing inter-fiber adhesion and doubling and simultaneously avoiding the physical damage to fibers by furnace rollers; and the shaping treatment can effectively relieve the internal stress generated in the production process of the precursor, thereby avoiding fibers from tension fracture in the process of preoxidation.
