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 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 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 management 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 separate broadcast domains with IEEE 802.3Q compliant VLANs, and empowers multimedia applications with multicast switching and CoS services.
