Chapter 1: About the ES4524M-PoE

Overview

The ES4524M-PoE is an intelligent Layer 2 PoE switch with 24 10/100/1000BASE-T ports, two of which are combination ports* that are shared with two SFP transceiver slots (see Figure 1-1, Ports 23-24).

The switch includes an SNMP-based management agent embedded on the main board, which supports both in-band and out-of-band management access.

It can easily enhance your network with full support for Spanning Tree Protocol, multicast switching, and virtual LANs. It brings order to poorly performing networks by segregating them into separate broadcast domains with IEEE 802.1Q compliant VLANs, and empowers multimedia applications with multicast switching and CoS services.

Switch Architecture

This Gigabit Ethernet 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.

For communications within the same VLAN, the switch uses store-and-forward switching to ensure maximum data integrity. The entire packet must be received into

*If an SFP transceiver is plugged in, the corresponding RJ-45 port is disabled for ports 23-24.
