Chapter 1: Introduction Overview The MIL-SM4804G switch is a stackable Fast Ethernet switch with 48 10BASE-T/ 1 100BASE-TX ports, 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 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 a

Introduction 1 Switch Architecture 2 The MIL-SM4804G employs a wire-speed, non-blocking switching fabric . This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switches also features full-duplex capability on all ports, which effectively doubles the bandwidth of each connection. The switches 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 c

Description of Hardware 1 3 Each port also supports IEEE 802.3x auto-negotiation of flow control , so the switch can automatically prevent port buffers from becoming saturated. 1000BASE-T/SFP Ports These are combination Gigabit RJ-45 ports with shared Small Form Factor Pluggable (SFP) transceiver slots (See Figure 1-1, Ports 25-26/49-50). If an SFP transceiver (purchased separately) is installed in a slot and has a valid link on the port, the associated RJ-45 port is disabled. The 1000BASE-T

Introduction 1 Stacking Ports The unit provides two stacking ports that provide a 4 Gbps stack backplane connection. You can stack up to four MIL-SM4804G units using Category 5 Ethernet cables (purchased separately). The Master button enables one switch in the stack to be selected as the master. This is the unit through which you manage the entire stack. The stacking ports can also be used as normal Ethernet ports in standalone mode by pressing the Uplink button. Master Button Uplink Butto
