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 IC39240/480 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 combination 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 embedded on the main
board. This agent supports both in-band 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 separate
broadcast domains with IEEE 802.1Q compliant VLANs and provide multimedia applications with multicast switching
and CoS services.
The system can operate as a stand-alone network or be used in combination with other IntraCore switches in the
backbone.
