3com 3CBLSG24PWR 2924-PWR Plus Managed L2 Power over Ethernet (PoE) Black Refurbished

3CBLSG24PWR Overview

Affordable, Managed Gigabit PoE Switching with Flexible Uplinks
The "smart" voice-ready 3Com® Baseline Switch 2924-PWR Plus is a web-managed Layer 2 Gigabit Power over Ethernet (PoE) 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 2924-PWR Plus has twenty-four 10/100/1000 PoE ports and four dual-purpose Gigabit ports (copper or SFP-based fiber) to connect to high-performance computers, servers, or core network backbones.

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 and advanced Access Control Lists (ACLs) for strengthening security.

The switch provides non-blocking performance— all ports perform at wirespeed which helps to eliminate network traffic bottlenecks. LACP link aggregation (IEEE 802.3ad) allows ports to be automatically grouped together to form an ultra-high-bandwidth connection that greatly expands bandwidth capacity to the network backbone.

The Baseline Switch 2924-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 2924-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 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.

Enhanced Intuituve Management Options
For networks that require more control, the switch web management interface provides an intuitive, menudriven process for even novice users to quickly and confidently configure the switch during initial setup and manage it during normal operation. Graphical switch and port views provide a clear understanding of switch status and configuration.

In addition, the web interface features individual port-traffic monitoring (port mirroring) and MAC address port mapping tables. A cable diagnostic tool lets users troubleshoot basic connectivity problems via the web management interface further simplifying network installation.

This Baseline Plus Switch is also supported by 3Com Network Supervisor (3NS) and 3Com Network Director (3ND) management software.

3NS and 3ND can be used to map the network topology, indicating what devices are connected, and on what ports. Switch management and software upgrades can be easily done. Other SNMP-based management tools may also be used.

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.
