Cisco AS5850 Product Overview
The Cisco AS5850 is a high-density, ISDN and modem WAN aggregation system that provides both
digital and analog call termination. It is intended to be used in service provider dial point-of-presence
(POP) or centralized enterprise dial environments.
The gateway components include hybrid trunk and port-handling cards (both functions are handled by
different components in the same slot), dedicated port-handling cards, dedicated trunk cards, route
switch controllers, power entry modules, and a blower unit to cool the chassis. An optional 2400W AC
power shelf is also available. The gateway is designed with environmental monitoring and reporting
functions to help maintain normal system operation and resolve 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 software images into Flash memory
remotely, without having to physically access the universal gateway, for fast and reliable upgrades.
This chapter provides physical and functional overviews to familiarize you with your new
Cisco AS5850. The chapter also contains physical descriptions of system hardware and major
components and functional descriptions of component features.
Descriptions and examples of software commands appear in this document only when they are
Note
necessary for installing the system hardware. For software configuration information, refer to the
Cisco AS5850 Universal Gateway Commissioning Guidelines that shipped with your system, or the
Cisco AS5850 Universal Gateway Operation, Administration, Maintenance, and Provisioning
Guide. These documents are available on Cisco.com (http://www.cisco.com), by selecting:

Power Requirements The Cisco AS5850 ships configured for either AC-input or DC-input power with loadsharing, depending on your order. AC-Input Power Specifications The Cisco AS5850 accepts AC-input power using a separate, self-contained AC-input power shelf, which converts AC-input power into DC output for use by the universal gateway.

    75V eventually trip the PEMF 60A circuit breaker, and you might have to reset the breaker. The Cisco AS5850 supports several types of logic cards with varying power requirements. As a result, each logic card DC-to-DC converter system is isolated from the distributed –48 VDC power, creating a more stable distributed power system.
