Chapter 1: Introduction
Overview
The ES3526XA is a Fast Ethernet switch with 24 10BASE-T/100BASE-TX ports and
two 1000BASE-T ports that operate in combination with two Small Form Factor
Pluggable (SFP) transceiver slots*(see Figure 1-1, Ports 25-26). The switch also
includes an SNMP-based management agent, which provides both in-band and
out-of-band access for managing the switch.
The ES3526XA provides a broad range of powerful features for Layer 2 switching,
delivering reliability and consistent performance for your network traffic. 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.

* If an SFP transceiver is plugged in, the corresponding RJ-45 port is disabled for ports 25-26.

Introduction

Switch Architecture
The ES3526XA 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.
This 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.
Network Management Options
With a comprehensive array of LEDs, the ES3526XA provides “at a glance”
monitoring of network and port status. The switch can be managed over the network
with a web browser or Telnet application, or via a direct connection to the console
port. The switch includes a built-in network management agent that allows it to be
managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It also has an
RS-232 serial port (DB-9 connector) on the rear panel for out-of-band management.
A PC may be connected to this port for configuration and monitoring out-of-band via a
null-modem serial cable. (See Appendix B for wiring options.)
For a detailed description of the advanced features, refer to the Management Guide.
Description of Hardware
10BASE-T/100BASE-TX Ports
The ES3526XA contains 24 10BASE-T/100BASE-TX RJ-45 ports. All ports support
automatic MDI/MDI-X operation, so you can use straight-through cables for all
network connections to PCs or servers, or to other switches or hubs. (See
“10BASE-T/100BASE-TX Pin Assignments” on page B-1.)
Each of these ports support auto-negotiation, so the optimum transmission mode
(half or full duplex), and data rate (10 or 100 Mbps) can be selected automatically. If
a device connected to one of these ports does not support auto-negotiation, the
communication mode of that port can be configured manually.
Each port also supports IEEE 802.3x auto-negotiation of flow control, so the switch
can automatically prevent port buffers from becoming saturated.
