Product Overview - Cisco 7000 Hardware Installation And Maintenance

C H A P T E R 1

Product Overview

The Cisco 7000 is the top-of-the-line Cisco 7000 series router/bridge that provides high reliability,
availability, serviceability, and performance. The system supports multiprotocol, multimedia routing
and bridging with a wide variety of protocols and any combination of Ethernet, Fast Ethernet, Token
Ring, Fiber Distributed Data Interface (FDDI), serial, multichannel channel attachment, and
High-Speed Serial Interface (HSSI) media. Network interfaces reside on modular interface
processors, which provide a direct connection between the high-speed Cisco Extended Bus (CxBus)
and the external networks.
Online insertion and removal (OIR) allows you to add, replace, or remove interface processors
without interrupting the system power or entering any console commands. The redundant power
option provides dual load-sharing power supplies that maintain input power without interruption if
one supply fails. Environmental monitoring and reporting functions enable you to maintain normal
system operation by resolving adverse environmental conditions prior to loss of operation. If
conditions reach critical thresholds, the system shuts down to avoid equipment damage from
excessive heat or electrical current. Downloadable software and microcode allow you to load new
images into Flash memory remotely, without having to physically access the router, for fast, reliable
system upgrades.
This chapter provides physical and functional overviews to familiarize you with your new system. It
contains physical descriptions of the system hardware and major components, and functional
descriptions of hardware-related features. Descriptions and examples of software commands appear
only when they are necessary for installing or maintaining the system hardware. For complete
command descriptions and instructions, refer to the related software reference publications.
