Introduction to the IGX Switches

This manual describes the IGX hardware that runs Release 9.2 of Cisco WAN Switching System Software. The descriptions cover both common and unique aspects of the IGX 8410, 8420, and 8430 models. The descriptions consist of hardware specifics and operational parameters at the system level. For a description of how to install and start an IGX switch, refer to the Cisco IGX 8400 Series Installation and Configuration publication.

Features of the IGX Switches

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, Inverse Multiplexing Over ATM (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 .2 Gbps bus for backup.

•Full compatibility with BPX system software.

•Up to 64 circuit lines, 32 trunks, and 3500 connections on the IGX 8420 and IGX 8430.

•IGX configuration and management through Cisco Wan Manager or the same standard user interface used with the BPX WAN switching system software.

•High performance switching suitable for a variety of protocols/applications, including Channel Associated Signaling (CAS), Asynchronous Transfer Mode (ATM), Frame Relay, 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.

•Factory upgrade program for IPX 16/32 feature cards. This upgrade excludes IPX 8-specific cards. Upgrades are available for the NTC, AIT, CDP, LDP, SDP, FRP, and FTC cards.
