Managed 48-Port 10/100BASE-T Layer 3 Switch

Description

48 10/100Mbps Ports for Workstation Connection
The switch provides 48 10/100Mbps ports supporting auto-sensing and auto-negotiation of network speeds and full/half duplex. These ports can connect to workstations and print servers, giving each a dedicated bandwidth. All ports support auto MDI/MDIX, allowing you to connect to workstations, servers, or other switches from any port without the need to change your usual straight-through twisted-pair cables.

Copper Gigabit for Servers
The copper Gigabit provides an inexpensive alternative solution to fiber-optic. Using your existing low-cost Cat. 5 copper twisted-pair wires as the transmission media, these ports allow you to instantly upgrade your servers to Gigabit capability without requiring you to install new, expensive fiber cables. The ports support 10/100/1000Mbps network speed auto-sensing, full/half duplex and auto MDI/MDIX.

2 Mini GBIC Slots for Flexible Fiber Connection
2 mini GBIC slots are provided for flexible fiber connection. You can select to install optional transceiver modules in these slots for 1000BASE-SX short/medium-distance or 1000BASE-LX long-distance fiber backbone attachment. Use of the mini GBIC will disable their corresponding built-in copper 10/100/1000Mbps copper connections.

Wire-speed IP Routing
The switch is designed for basic IP routing, with instant support for Windows, Unix and Internet environments. It provides wire-speed non-blocking switch fabrics with hardware-based packet filtering/forwarding. Packet routing is performed by on-board ASICs at speeds many times faster than CPU-based routers. 

Seamless Integration
The DES-3350SR can be instantly integrated into any existing network for seamless integration of Layer 2 and Layer 3 packet switching. With multi-layer support for every port, you can start with Layer 2 switching, then upgrade to Layer 3 routing anytime by simply re-configuring the ports. You can flexibly segment the network into domains and sub-domains, using (1) subnet IDs and user IP numbers to route traffic, and (2) custom filters based on users' physical MAC addresses to filter extraneous traffic. At Layer 2, the switch uses auto-learned and user-defined MAC addresses to discard and forward packets. At Layer 3, it looks at the user-specified routing table to route packets to their destinations.

Ready for Multi-media Applications
With Priority Queues and IP multicast (IGMP snooping) support, Quality of Services (QoS) can be guaranteed for successful execution of delay-sensitive applications like video conference.

Flow Control to Prevent Packet Loss
The switch supports standard IEEE 802.3x Flow Control. Working in conjunction with buf fer overrun auto-detection, this full-duplex data transfer mode provides protection against possible data loss for 802.3x supported servers directly connected to the switch.

Port Trunks for Aggregated Bandwidths
With low cost per port, port trunking provides an easy and economical alternative solution for server connection to attain Gigabit bandwidth. Up to 8 10/100Mbps ports can be combined together to create a load-sharing aggregated bandwidth to a server.
