"Incrediable value,flexiable management capabilities and energy efficient power saving."
 

Help deliver flexible, energy-conscious gigabit switching with PowerConnect™ 5548, featuring robust security, stacking and management. With 48 wire-speed Gigabit Ethernet (GbE) ports available for campus switching, the 5548 scales with your network as it grows.
 

HIGHLIGHTS:

High throughput: Supports wire-speed performance with up to 48 ports of GbE and two 10GbE uplink ports for 40Gbps of bandwidth.

Energy conscious: Energy Efficient Ethernet (EEE)architectue helps reduce power to ports in sleep mode or remode or remove power to inactive ports.

Scalable: Manages up to 8 wire-speed switches as a single unit.
 

KEY FEATURES:

Rapid Deployment and Configuration

  • Help save time and deployment costs by simplifying your network rollout
  • Automatically assing switch configuration and IP address via DHCP or local USB during initial rollout
  • Can configure up to eight switches in a stack without pressing a single key or setting up a console connection

Robust Management

  • An industry-standard CLI
  • Remote management using an embedded web server
  • Support for SNMP-based management applications
 

VoIP Functionality

  • Help ensure that VoIP traffic is prioritized in the event of resource contention through the voice VLAN function
  • LLDP-Med provides detailed network topology records, emergency call service via IP phone location information and troubleshooting data
 

Automated Security
Select from multiple security levels,with options that include such industry-standard features as:

  • SSH/SSL management encryption
