Cisco 7206 Router Shelf

Cisco 7206 Router Shelf

This section provides physical and functional overviews of the Cisco 7206 router shelves. It contains physical descriptions of the router hardware and major components and functional descriptions of hardware-related features.

The Cisco 7206 router supports call signaling for PRI interfaces; packet processing; and multiprotocol, multimedia routing and bridging with all commonly used high-speed LAN and WAN interfaces, including Ethernet, Fast Ethernet (FE), Asynchronous Transfer Mode (ATM), High-Speed Serial Interface (HSSI), and Fiber Distributed Data Interface (FDDI).

The Cisco 7206 router shelf handles upper layer routing tasks and provides the following features:

OIR—Allows you to add, replace, or remove port adapters without interrupting the system or entering any console commands.

Dual hot-swappable, load-sharing power supplies—Provide system power redundancy; if one power supply or power source fails, the other power supply maintains system power without interruption. Also, when one power supply is powered off, the second power supply immediately takes over the router’s power requirements without interrupting normal operation.

Environmental monitoring and reporting functions—Allow you to maintain normal system operation by resolving adverse environmental conditions prior to loss of operation.

Downloadable software—Allows you to load new images into Flash memory remotely, for fast, reliable upgrades without having to physically access the Cisco 7206 router.
