摘要

Accessing shared resources by intelligent components is disclosed. In various embodiments, a system is configured to select a host for a bus and includes a bus configured to have a host, a shelf controller configured to host the bus and access an external interface via the bus, a plurality of line cards configured to host the bus and access an external interface via the bus, and a host selection device configured to select the shelf controller or one of the line cards as the host of the bus.

主权项

1. A system configured to select a host for a bus comprising:
a bus for accessing an external interface and configured to have a host; a shelf controller configured to interface with a plurality of line cards and a central storage device; the central storage device communicatively coupled to the shelf controller and configured to store boot code for said plurality of line cards; each of said plurality of line cards configured to execute boot code retrieved via said shelf controller to thereby enable line card operation; and a host selection device configured to select the shelf controller or an operational line card as the host of the bus.
