Chapter 1: Introduction

Overview

The MIL-SM4804G switch is a stackable Fast Ethernet switch with 48 10BASE-T/
100BASE-TX ports, and two 1000BASE-T ports1 that operate in combinat ion with
two Small Form Factor Pluggable (SFP) transceiver slots. These switches also
provide two 1 Gbps built-in stacking ports for connecting up to four MIL-SM4804G
units in a stack. The stacking ports can also be used as normal Ethernet ports in
standalone mode. The switch also includes an SNMP-based managemen t agent,
which provides both in-band and out-of-band access for managing the switch.
The MIL-SM4804G 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 se parate
broadcast domains with IEEE 802.3Q compliant VLANs, and empowers multime dia
applications with multicast switching and CoS services.
