Chapter 1: Introduction

Overview

The SMC8926EM and SMC8950EM are intelligent multilayer switches (Layer 2, 3) with 24/48 10/100/1000BASE-T ports, four of which are combination ports

that are shared with four SFP transceiver slots (see Figure 1-1, Port s 21-24/45-48). The rear panel provides two slots for single-port 10 Gigabit Ethernet hot-swappable expansion modules, and two stacking ports. Units can be stacked up to eight high through the built-in stacking ports that provide a 50 Gbps stack backplane.

The switches include an SNMP-based management agent embedded on the main board, which supports both in-band and out-of-band access for managing the stack.

These switches can easily tame your network with full support for Spanning Tree Protocol, Multicast Switching, Virtual LANs, and IP routing. It brings order to poorly performing networks by segregating them into separate broadcast domains with IEEE 802.1Q compliant VLANs, empowers multimedia applications with multicast switching and CoS services, and eliminates conventional router bottlenecks.

These switches can be used to augment or completely replace slow legacy routers, off-loading local IP traffic to release valuable resources for non-IP routing or WAN access. With wire-speed performance for Layer 2 and Layer 3, these switches can significantly improve the throughput between IP segments or VLANs.

Switch Architecture

These Gigabit Ethernet switches employ a wire-speed, non-blocking swit ching fabric. This permits simultaneous wire-speed transport of multiple packets at low latency on all ports. The switches also feature full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.

For communications between different VLANs, these switches use IP routing. For communications within the same VLAN, they use 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 befo re bein g forwarded . Th is prevents errors from being propagated throughout the network.

These switches include built-in stacking ports that enable up to eight units to be connected together through a 48 Gbps stack backplane. The switch stack can be managed from a master unit using a single IP address.

These switches also include two slots on the rear panel for slide-in single-port 10GBASE modules with XFP transceivers.

Network Management Options

These switches contain a comprehensive array of L EDs for “at-a-gl ance” moni toring of network and port status. They also include a management agen t that allows you to configure or monitor the switch using its embedded management software, or via SNMP applications. To manage each switch, you can make a direct connection to the console port (out-of-band), or you can manage the switches through a network connection (in-band) using Telnet, the on-boa rd web agent, or SNMP-based net work management software.

For a detailed description of both switches’ advanced features, refer to the Gigabit Ethernet Switch Management Guide.

Optional Redundant Power Supply

The switch supports an optional Redundant Power Supply (RPS), that can supply power to the switch in the event the internal power supply fails.

Power Supply Sockets

There are two power sockets on the rear panel of each switch. The standard power socket is for the AC power cord. The socket labeled “RPS” is for the optional Redundant Power Supply (RPS).
