Chapter 2: Overview
2. Overview
2.1 Introduction
The Gigabit Managed PoE+ Switches provide a reliable infrastructure for your business network. These switches improve the avail-
ability 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 provide the ideal combination of affordability
and capabilities for entry-level networking. Use them in small business or enterprise applications.
Three models are available:
• LPB2910A
• LPB2926A
• LPB2952A
The switches support advanced security management capabilities and network features, including data, voice, security, and
wireless technologies. The switches are easy to deploy and configure, providing stable and quality network services.
2.2 Switch Architecture and Network Management Options
2.2.1 Switch Architecture
The switch performs wire-speed, non-blocking switching. This allows 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.
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.
2.2.2 Network Management Options
You can manage the switch 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. Connect a PC to this port for configuration and moni-
toring out-of-band via a null-modem serial cable.
NOTE: For a detailed description of the management features, refer to the user’s manual.
