Chapter 1: Introduction
Overview
The ES3526YA/ES3550YA switches are stackable Fast Ethernet switches with 24
and 48 10BASE-T/100BASE-TX ports, respectively, and two 1000BASE-T ports

that operate in combination with two Small Form Factor Pluggable (SFP) transceiver
slots. These switches also provide two 1 Gbps built-in stacking ports for connecting
up to eight ES3526YA or four ES3550YA units in a stack. If you connect both
ES3526YA and ES3550YA units in the same stack, then you can only stack up to
four units. The stacking ports can also be used as normal Ethernet ports in
standalone mode. The switch also includes an SNMP-based management agent,
which provides both in-band and out-of-band access for managing the switch.
The ES3526YA/ES3550YA provides a broad range of powerful features for Layer 2
switching, delivering reliability and consistent performance for your network traffic.
They bring order to poorly performing networks by segregating them into separate
broadcast domains with IEEE 802.3Q compliant VLANs, and empowers multimedia
applications with multicast switching and CoS services.
