Chapter 2: Overview
2. Overview
2.1 Introduction
The 24 + 4 or 48 + 4 Managed Gigabit Switches with 4 SFP+ 10G are easy-to-implement managed Ethernet switches. Models
have 24 or 48 ports of Gigabit Ethernet connectivity plus four 10G ports. These switches deliver more intelligent features to
improve the availability of your critical business applications, protect your sensitive information, and optimize your network band-
width to deliver information and applications more effectively. Both switches support advanced security management capabilities
and network features including data, voice, security, and wireless technologies. These switches are easy to deploy and configure,
providing stable and quality performance network services. Typical applications include small business and enterprise.
2.2 Features
• Performs wire-speed, non-blocking switching to enable wire-speed transport of multiple packets at low latency on all ports
simultaneously.
• Provides full-duplex capability on all ports, which effectively doubles the bandwidth of each connection.
• 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.
• You can also manage the switch over the network with a Web browser or Telnet application. Manage it in-band using SNMP or
RMON (Groups 1, 2, 3, 9) protocols. Configure and monitor the switch out-of-band via a null-modem serial cable. (See
Appendix C for wiring options.)
