Description

3COM 48-port baseline 2250 plus switch 10/100 and 2 configurable 10/100/1000 or sfp gigabit ports (retial)

The "smart" 3Com® Baseline Switch 2250 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 interface and advanced features (VLANs, IEEE 802.1X authentication and Rapid Spanning Tree), this switch is a cost-effective way to provide a converged network.

Features

Web-managed Layer 2 10/100 Ethernet switch

Forty-eight 10/100 ports and two dual-purpose Gigabit ports (copper or SFP-based fiber)

No need to configure the switch if default settings are acceptable

If more control desired, the switch interface allows even novice users to quickly and confidently configure the switch

Switch can be managed with SNMP-compatible software

VLANs segment the network by grouping users based on their data or traffic requirements, making the best use of available bandwidth

Voice over IP (VoIP) traffic can be automatically assigned to a voice-dedicated VLAN, optimizing this delay-sensitive traffic

With manual link aggregation, group ports together to form an ultra-high-bandwidth trunked connection to the network backbone and help prevent traffic bottlenecks

IEEE 802.1X network access control provides standards-based security combined with local authentication

Rapid Spanning Tree Protocol (RSTP) support improves network compatibility, scalability and availability

IGMP snooping and query and multicast filtering optimizes network performance

Easy-to-use browser based tools allow remote detection of cable issues
