Business Ethernet Switch 220


Features & Benefits
*
A stackable solution - Enables you to grow your network using the same IP address, for easy configuration and management.
*
Support for Power over Ethernet (PoE) - Provides power to devices such as Voice Over IP handsets or Wireless access points.
*
Provides the building blocks for a data information infrastructure - Help increase workforce productivity, reduce operating expenses and simplify network management.
*
Convergence ready functionality - Prioritization of the data on the network is essential in order to ensure that mission critical applications such as voice are delivered in a timely manner and treated differently to non-time sensitive data. The Business Ethernet Switch 220 puts traffic into different priority queues to ensure that data is properly classified.
*
Supports IP communications technologies – Support for voice over wireless/IP, Unified Messaging, conferencing and collaboration, video, Customer Relationship Management and mobility - resulting in increased user productivity and better business results.
*
Simple installation - With the Business Ethernet Switch 220, installation and connectivity to desktop PCs, printers and other networked devices is simplified thanks to support for auto-negotiation of speed and duplex mode, auto-MDI/MDIX, easy-to-read LEDs and default IP address.
*
Simplified management - The Nortel SMB product portfolio offers a unique management experience through the Nortel Business Element Manager. This powerful tool enables management for the entire small to mid-sized business portfolio including the Business Ethernet Switch Family. Allows you to simplify all your management needs through the use of one consistent, familiar interface.
