Power Cord Safety
Please read the following safety information carefully before installing the switch:
WARNING: Installation and removal of the unit must be carried out by qualified personnel
only.
• The unit must be connected to an earthed (grounded) outlet to comply with
international safety standards.
• Do not connect the unit to an A.C. outlet (power supply) without an earth (ground)
connection.
• The appliance coupler (the connector to the unit and not the wall plug) must have
a configuration for mating with an EN 60320/IEC 320 appliance inlet.
• The socket outlet must be near to the unit and easily accessible. You can only
remove power from the unit by disconnecting the power cord from the outlet.
• This unitoperates under SELV (Safety Extra Low Voltage) conditions according to
IEC 60950. The conditions are only maintained if the equipment to which it is
connected also operates under SELV conditions.
France and Peru only
This unit cannot be powered from IT†supplies. If your supplies are of IT type, this unit
must be powered by 230 V (2P+T) via an isolation transformer ratio 1:1, with the
secondary connection point labelled Neutral, connected directly to earth (ground).
†Impédance à la terre
When using a fiber optic port, never look at the transmit laser while it is
powered on. Also, never look directly at the fiber TX port and fiber cable
ends when they are powered on.
Ne regardez jamais le laser tant qu'il est sous tension. Ne regardez
jamais directement le port TX (Transmission) à fibres optiques et les
embouts de câbles à fibres optiques tant qu'ils sont sous tension.

Chapter 1: Introduction
Overview
The TigerSwitch 10/100/1000, SMC8126L2, is an intelligent Layer 2 switch with 26
10/100/1000BASE-T ports, four of which are combination ports*that are shared with
four SFP transceiver slots (see Figure 1-1, Ports 21-24).
The SMC8126L2 includes an SNMP-based management agent embedded on the
main board, which supports both in-band and out-of-band access for managing the
switch.
The switch can easily tame your network with full support for Spanning Tree
Protocol, Multicast Switching, and Virtual LANs. 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.

Introduction

Switch Architecture
The SMC8126L2 employs a wire-speed, non-blocking switching fabric. This permits
simultaneous wire-speed transport of multiple packets at low latency on all ports. It
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.
Network Management Options
The SMC8126L2 contains a comprehensive array of LEDs for “at-a-glance”
monitoring of network and port status. It also includes a management agent that
allows you to configure or monitor the switch using its embedded management
software, or via SNMP applications. To manage this switch, you can make a direct
connection to the console port (out-of-band), or you can manage the switch through
a network connection (in-band) using Telnet, the on-board web agent, or
SNMP-based network management software.
For a detailed description of this switch’s advanced features, refer to the
Management Guide.
