2 Overview
2.1 Introduction
The 10-, 26-, or 48-Port Gigabit Managed Switch is an affordable managed switch that is a key part of a reliable infrastructure for your
business network. This switch delivers the kind of intelligent features you need:
• to improve the availability of your critical business applications;
• to protect your sensitive information; and
• to optimize your network bandwidth.
Easy to set up and use, the Gigabit Managed Switch provides stable and quality performance to support all types of data, voice, security, and
wireless technologies. It provides the ideal combination of affordability and capabilities for entry-level networking for small businesses or home
office applications and helps create a more efficient, better-connected workforce.

NOTE: The 26- and 48-Port Gigabit Managed Switches’ front panels are similar to the 10-Port Switch. All three switches have the same Power
LED and Reset/Default. The LGB1108A has (8) 10/100/1000BASE-T RJ-45 ports, (2) TP and 100/1G SFP ports, (16) switch TP LEDs, and
(1) RJ-45 console port. The LGB1126A has (20) 10/100/1000BASE-T RJ-45 ports, (4) dual-media UTP/SFP ports, (2) SFP ports, (40) switch
TP LEDs, and (1) RJ-45 console port. The LGB1148A has (44) 10/100/1000BASE-T RJ-45 ports, (4) dual-media UTP/SFP ports, (88) switch
TP LEDs, and (1) DB9 console port.
2.2. Features
• Switch Architecture: This switch performs a wire-speed, non-blocking switching fabric, which enables wire-speed transport of multiple
packets at low latency on all ports simultaneously. The switch also features full-duplex capability on all ports, which effectively doubles the
bandwidth of each connection. It uses store-and-forward technology to ensure maximum data integrity. With this technology, 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 switch can also be managed over the network with a Web browser or Telnet application. The switch
includes a built-in network management agent that allows it to be managed in-band using SNMP or RMON (Groups 1, 2, 3, 9) protocols. It
also has an RJ-45 console port connector on the front panel for out-of-band management. A PC may be connected to this port for
configuration and monitoring out-of-band via a null-modem serial cable. (For more information on cabling, see Chapter 9: Cables.)
NOTE: For a detailed description of the management features, refer to the User’s Manual.
