Cisco 7206 Router Shelf

This section provides physical and functional over views of t he Cisco 7206 router shelves . It cont ains

physical descriptions of the router hardware and major components and functional des criptions of

hardware-related features.

The Cisco7206 router supports call signaling for PRI interfaces; packet processing; and

multiprotocol, multimedia routing and bridging with all commonl y used high-spe ed LAN and W AN

interfaces, including Ethernet, Fast Ethernet (FE), Asynchronous Tra nsfer 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 maintai ns system power without

interruption. Also, when one power supply is powered off, the second po wer supply immediat ely

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 th e Cis co 7206 router.

Figure1-19 shows the significant Cisco 7206 router components.

Note In Figure1-19 a blank port adapter is installed in slot 5. To ensure adequate airflow across the

port adapters, each slot must be filled with either a port adapter or a blank port adapter.
