Chapter 1: Introduction
Overview
The ES3528M-PoE switch is an intelligent PoE switch with 24 10/100BASE-T ports,
two 10/100/1000BASE-T ports, and two Gigabit combination ports
1
that are
comprised of a RJ-45 port and an SFP transceiver slot. There is also 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.
The switch 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 802.1Q compliant VLANs, and empower multimedia applications
with multicast switching and CoS services.

Switch Architecture
This switch employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all ports.
This 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.

corresponding RJ-45 port is disabled.
