Introduction to the Cisco IGX 8400 Series

This guide describes the IGX hardware that runs Release 9.3.30 or later of the Cisco WAN Switching System Software (switch software) and provides instructions for provisioning services across networks containing an IGX node. The descriptions cover both common and unique aspects of the
Cisco IGX 8410, 8420, and 8430 models.

For information about the BPX, see Chapter 1, "The BPX Switch: Functional Overview ," in the Cisco BPX 8600 Series Installation and Configuration guide.

Features of the IGX 8400 Series

Like other Cisco switches, the IGX node operates in public or private wide-area networks (WANs). An IGX node can support OC3, T3, E3, T1, E1, ATM standards-based inverse multiplexing (also known as IMA) for T1 or E1, fractional T1 or E1, or subrate digital transmission facilities. The IGX cell relay technology provides maximum throughput with minimum delays. Cell relay performance characteristics are the heart of efficient digital networks and make the IGX node an ideal choice for a high-performance, multimedia platform. Key features of the IGX switch include:

A 1 gigabit per second (Gbps) cellbus for high-speed switching and a redundant 0.2 Gbps bus for backup.
Full compatibility with Cisco BPX 8600 series system software.
Up to 64 lines, 32 trunks, and 3500 connections on the Cisco IGX 8420 and Cisco IGX 8430 models.
IGX configuration and management through Cisco WAN Manager or the switch software command-line interface (CLI).
High performance switching suitable for a variety of protocols/applications, including Asynchronous Transfer Mode (ATM), Frame Relay (FR), voice, fax, slow-scan and full-bandwidth video, and synchronous or asynchronous data.
Six cabinet models, which consist of:

An 8-slot standalone unit
An 8-slot rack-mount unit
A 16-slot standalone unit
A 16-slot rack-mount unit
A 32-slot standalone unit
A 32-slot rack-mount unit

Redundancy of controller cards, service module cards, system buses, and power supplies to provide hardware reliability.
Hot-swappable modules to facilitate non-stop operation: service cards, NPMs, AC power supplies, and fan tray assembly.
110/220 VAC and -48 DC power options for use in varied network environments.
