CHAPTER 2: OVERVIEW
2.1 DESCRIPTION
The Gigabit Managed Ethernet Switches are affordable managed switches that provide a reliable infrastructure for your business
network. These switches deliver the intelligent features you need to improve the availability of your critical business applications, protect
your sensitive information, and optimize your network bandwidth to deliver information and applications more effectively. Easy to set up
and use, the switches are ideal for entry- level networking, including small business or enterprise applications.
The Gigabit Managed Ethernet Switches have 10, 26, or 48 ports. The switches provide advanced security management capabilities and
network features that support data, voice, security, and wireless technologies.
Three Gigabit Managed Ethernet Switch models are available:
Gigabit Managed Ethernet Switch - 10-Ports (LGB1110A)
Gigabit Managed Ethernet Switch - 26-Ports (LGB1126A-R2)
Gigabit Managed Ethernet Switch - 52-Ports (LGB1152A)
2.2 SWITCH ARCHITECTURE
The switch transports multiple wire-speed 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.
This switch 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.
2.3 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. You can connect a PC to this port for configuration and monitoring out-
of-band via a null-modem serial cable.
NOTE:
For a detailed description of the management features, refer to the user’s manual.
