Presented herein are improvement to computer system architecture. In one embodiment, a method includes reconfiguring system interconnect links disposed between a first central processing unit socket and a second central processing unit socket, disposed together on a single motherboard, as peripheral bus links; and transmitting electrical signals, via the peripheral bus links, and via a printed circuit board that bridges the second central processing unit socket, to at least one input/output functional block that is disposed on the single motherboard and that is selectively connectable to the second central processing unit socket.

An apparatus for connecting a router blade to a router chassis is provided. The apparatus includes an engagement portion; a first side portion coupled with the engagement portion; and a second side portion coupled with the engagement portion. The engagement portion includes a connector system that is operable to couple a router blade with a router chassis. The first side portion is operable to engage the router blade and the router chassis. The second side portion is operable to engage a router blade and the router chassis. The engagement portion, first side portion, and second side portion are sized to engage the router chassis and receive the router blade.

A method and system for configuring a network device is provided. In one implementation the method and system may include directing, via a multiplexer, a group of signals defined by a serial communication format from a primary serial configuration interface to a communication port in a CPU. A universal-serial-bus-to-serial (USB) signal may be detected at a USB interface and converted by a USB-to-serial converter circuit to the serial communication format and directed, via the same multiplexer, to the universal-asynchronous-receiver-transmitter instead of the serial signals from the primary serial configuration interface. A detection signal may be communicated from the USB-to-serial converter circuit to the multiplexer. Alternatively, the detection signal may be directed to the CPU, which may then communicate a selection signal to the multiplexer.

Automatically switching console connection

A bridging device has at least two ports. The first port allows the device to communicate with devices on an expansion bus and at least one other port to allow the bridge to communicate with a system memory on a system bus or other devices on another expansion bus. The device is capable of identifying at least two regions in memory, a descriptor region and a data region. A descriptor provides information about segments of data in the data region. The bridge may detect descriptors read from the memory, extract information related to data associated with those descriptors and use this information to perform prefetching of data from the system memory.

A system and method for configuring a slot to be compatible with both modules that are compliant with the isolation requirements for power over Ethernet and modules that are not compliant.

Providing compatibility with both electrically isolated and non-isolated modules in an ethernet system

A router includes WIC and Network Module slots that be reconfigured to hold cards and network modules having different form factors. A motherboard/midplane arrangement provides for a field replaceable motherboard that can be replaced without removing the router from the rack.

A bridging device has a first port to allow the device to communicate with other devices on an expansion bus and a second port to allow the device to communicate with devices on a second bus. The device also includes a memory to store data and a processor or logic to prefetch data upon request from a device on the expansion bus, tag any remaining prefetched data with an identifier upon a disconnecting event, and retain the prefetched data until a discarding event occurs. A method of controlling prefetch transactions on an expansion bus involves prefetching data across a primary bus for a device on a secondary bus. An indication that a disconnecting event has occurred is detected and any remaining prefetched data remaining is tagged with an identifier and retained. The data may be prefetched from a controlled prefetch region in the memory.
