Affordable, Web-managed 10/100 Power over Ethernet Switching with Gigabit Uplinks
The "smart" voice-ready 3Com Baseline Switch 2426-PWR Plus is a web-managed Layer 2 10/100 Ethernet switch. It offers enterprise-class features, customized and priced for small- and mid-sized organizations. With an easy-to-use switch interface and advanced features (VLANs, PoE, IEEE 802.1X authentication and Rapid Spanning Tree), this switch is the most cost-effective way to provide a converged network.
Layer 2 Switching with Advanced Features
The Baseline Switch 2426-PWR Plus has twenty-four 10/100 ports and two dual-purpose Gigabit ports (copper or SFP-based fiber) to connect to high-performance computers, servers, or core network backbones.
The switch provides non-blocking performance- all ports perform at wirespeed which helps to eliminate network traffic bottlenecks. Manual link aggregation allows ports to be grouped together to form an ultra-high-bandwidth connection that greatly expands bandwidth capacity to the network backbone.
This "smart" switch has the features that help build a voice ready network, with support for auto-voice VLAN, Power over Ethernet, SNMP-based management, IGMP snooping and query and IEEE 802.1X for strengthening security.
The Baseline Switch 2426-PWR Plus also supports Spanning Tree and Rapid Spanning Tree, traffic prioritization, priority queuing and VLANs. These switching features ensure optimal use of available bandwidth as traffic flow is directed according to the needs of the business.
Power over Ethernet
The Baseline Switch 2426-PWR Plus provides inline power to attached devices- access points, Voice over IP (VoIP) phones, IP security cameras, etc.- via industry-standard IEEE 802.3af and pre-standard 802.3at Power over Ethernet over a single Ethernet cable, resulting in significant deployment cost savings.
No Switch Setup Required
This Baseline Plus switch is operational straight out-of-the-box; as long as default settings are acceptable, there is no need to configure the switch. If desired, the switch can be configured using a web browser or SNMP management software.
Smart Browser-Based User Interface
For networks that require more control, the switch management interface- completely redesigned to enhance useability- allows even novice users to quickly and confidently configure the switch during initial setup or normal operation. The Switch family also supports a compact Command Line Interface (CLI) that is accessed via the front panel console port. Using the CLI, major switch management options can be quickly configured.
In addition, the web interface features individual port-traffic monitoring (port mirroring) and a unique, quick-glance switch status review. A cable diagnostic tool lets users troubleshoot basic connectivity problems via the web management interface, further simplifying network installation.
