Product Description

The Baseline Switch 2948-SFP Plus has forty-eight 10/100/1000 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, 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.

Main Features:

  • Managed Layer 2 Gigabit Ethernet switch
  • Jumbo Frame support for reduced network load
  • No need to configure the switch if default settings are acceptable
  • IGMP snooping and multicast filtering optimizes network performance
  • Easy-to-use browser based tools allows remote detection of cable issues
  • Rapid Spanning Tree Protocol (RSTP) support improves network compatibility, scalability and availability
  • IEEE 802.1X network access control provides standards-based security combined with local authentication
  • Switch can be managed with SNMP-compatible software like 3Com Network Supervisor and Network Director
  • Auto-voice VLAN automatically assigns Voice over IP (VoIP) traffic to a voice-dedicated VLAN, optimizing this delay-sensitive traffic
  • VLANs segment the network by grouping users based on their data or traffic requirements, making the best use of available bandwidth
  • With LACP link aggregation, automatically group ports together to form an ultra-high-bandwidth trunked connection to the network backbone and help prevent traffic bottlenecks
  • Forty-eight 10/100/1000 ports and 4 Gigabit SFP ports, dual-purposed with 4 of the 10/100/1000 ports (configurable as 10/100/1000 or SFP); front-panel console port for CLI management
