| A switch is a device with which it is possible to connect computers into a (local area) network, provided your computers all have an appropriate networking device installed. Switches can be daisy chained to form larger networks and come in managed and unmanaged variaties. The unmanaged versions generally cannot filter data and will forward any data that is fed into them, so they are better suited for small networks. Switches are easy to set up (just plug in the network cables) and allow you to share printers, storage space and other network resourses with your entire home or office network. |

such as Fast Ethernet, including 100BASE-LX (Ethernet in the First Mile), and Gigabit Ethernet copper or fiber links.
Rapid Spanning Tree, automatic link aggregated stack-wide trunking, resilient stacking and optional redundant power supply support deliver robust performance and fault tolerance.
- User network login with IEEE 802.1X and RADIUS, combined with RADIUS Authenticated Device Access (RADA), based on MAC address, provide secure network access control at the network edge.
- Authenticated users can be automatically placed into a specific VLAN, restricting access only to the data needed.
- Secure Shell (SSH) encryption of login passwords, management VLANs, and management station "trusted IP address" lists help protect network from rogue management threats.
- LACP (802.3ad) intelligently detects configuration duplicity and uses it to trunk up to 4Gb of bandwidth across a stack, while nullifying single points of failure from the network's edge infrastructure.
- Advanced Layer 4 functionality automatically identifies and prioritizes real-time or business-critical applications, such as SAP, voice, and video.
- Backup and restore functionality enables switch configurations to be captured and reapplied individually to a single switch or across a whole network at a push of a button.
- Forwarding up to 6.6 million pps, the Switch 4400 operates at full wire speed on all ports.
- Stackable architecture increases scalability and allows high-speed trunks between workgroup and other resources.
- Add optional switching modules to provide resilient high-speed connections, such as Gigabit Ethernet backbone links, or 100BASE-LX 10 links for Ethernet in First Mile over Point to Point Fiber (EFMF).
- 3Com® Network Supervisor software (60-day trial version included) supports automatic prioritization of real-time or critical traffic.
- Mix and match 24-port and 48-port SuperStack 3 Switch 4400s to create a resilient stack of up to a total of 384 10/100 connections.
