Chapter 1: Introduction

Overview

The Matrix V-Series V2H124-24P switch contains 24 10BASE-T/100BASE-TX RJ-45 ports and two combination ports—10/100/1000BASE-T ports that operate in combination with Small Form Factor Pluggable (SFP) transceiver slots. An optional SFP stacking transceiver is available for connecting up to eight units to a 1 Gbps stack backplane.

All the 10BASE-T/100BASE-TX ports on this switch support IEEE 802.3af draft standard (802.3af) Power-over-Ethernet capabilities. Each port can detect connected 802.3af-compliant network devices, such as IP phones or wireless access points, and automatically supply the required DC power.

As well as its Power-over-Ethernet capabilities, the switch provides comprehensive network management features, such as Spanning Tree Protocol, multicast switching, virtual LANs, and Layer 2/3/4 CoS services that provide reliability and consistent performance for your network traffic.

Switch Architecture

The Matrix V-Series V2H124-24P switch employs a wire-speed, non-blocking switching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switch also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

The switch uses store-and-forward switching to ensure maximum data integrity. With store-and-forward switching, the entire packet must be received into a buffer and checked for validity before being forwarded. This prevents errors from being propagated throughout the network.
