Chapter 1: Introduction
The IntraCore IC39240/480 24-port Layer 2+ Managed Gigabit Switch is a high-performance network switch used to
reduce network congestion and application response times. The 24-port/48-port IntraCore IC392 40/480 multi-protocol
switch supports Layer 2+ and Gigabit Ethernet switching. The switch has 24/48 10/100/1000BaseT ports with Auto-
Uplink and has 4 combinatio n ports used for sharing with SFP mini GBICs. Gigabit fiber technology is used to
connect two switches together. The switches also have an SNMP-based management agent emb edded on the main
board. This agent supports both in-b and and out-of-band access for managing the switch.
These switches have a broad range of features for Layer 2+ switching delivering reliability and consistent
performance for network traffic. The switches improve network performance by segregating them into s eparate
broadcast domains with IEEE 802.1Q compli ant VLANs and provide multimedia applications with multicast s witching
and CoS services.
The system can operate as a stand-alon e network or be used in combination with other IntraCore switches in the
backbone.
