Managed 48-Port 10/100 Switch + 2 combo Gig copper/SFP uplinks
EOL
Description:

48 10/100Mbps Ports for Workstations
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 uplink, 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.

VLANs for Enhanced Security & Performance
VLANs improve security and bandwidth utilization by limiting the broadcast domains and confining intra-group traffic within their segments. To segment up the network, nodes supporting

2 Mini GBIC Slots for Flexible Fiber Connection
2 mini GBIC slots are provided for flexible fiber connection. You can select to install an optional transceiver module in the GBIC slot 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.

VLANs for Enhanced Security & Performance
VLANs improve security and bandwidth utilization by limiting the broadcast domains and confining intra-group traffic within their segments. To segment up the network, nodes supporting IEEE 802.1Q VLAN Tagging connected to the switch can be grouped into different Virtual LANs (VLANs). The switch also supports GVRP (GARP VLAN Registration Protocol) for automatic VLAN configuration distribution.

Priority Queues for QoS
The switch supports Layer 2 802.1p Priority Queue control. Each packet going through the switch can be assigned a queue priority number (in the priority bit). Packets with a higher priority number are allowed to pass first. This function support allows you to attach video servers to the switch to run delay-sensitive applications like video conference.

IGMP Snooping for Broadcast Control
The switch listens to IGMP (Internet Group Management Protocol) messages to build mapping table and associate forwarding filters. It dynamically configures the switch ports to forward IP multicast traffic only to those ports associated with multicast hosts.

Port Mirroring
This function allows you to mirror adjacent ports for the purpose of analyzing incoming and outgoing packets where packet patterns can be studied.

Port Trunks for Aggregated Bandwidths
Port trunking on 10/100Mbps ports provides an economical alternative for server connection to attain Gigabit bandwidth. Up to 8 10/100Mbps ports can be combined together to create a multi-link load-sharing aggregated bandwidth to a server.
