48 - 10/100 Switched RJ-45 ports deliverup to 200Mbps of throughput per port

4 - 10/100/1000 Switched RJ-45 Gb Uplink

Ports (with 2 shared mini-GBIC ports)

WebView monitoring allows administrators

to view the current status and configuration
using their favorite web browser

Port based and 802.1q based VLAN s support

up to 256 VLANS

Port Trunking for up to 8 groups allows you

to increase your bandwidth for each
uplink or Server connection

Port configuration settings for Link, Speed,

Auto MDI/MDIX, Flow Control, and more

Fully rack-mountable using the included

rack-mounting hardware

Auto MDI/MDIX per port allows for automatic

Cable detection

MAC Address table supports up to 8K

MAC Address entries

Optimal platform to support real-time

applications like voice and video by providing
features like IGMP snooping, multiple
queues (4) with appropriate
scheduling techniques, prioritization of
traffic based on L2/L3 priority*, and line
rate forwarding mechanisms

Secure control via SSH for Telnet interface

and SSL for HTTP interface

User/Network security via 802.1x (with

Radius authentication) and MAC-based
filtering

Containment of storms - Broadcast, Multicast,

and Unknown Unicast

Expandability and availability increased

across multiple switches using Link Aggregation

SNMP and RMON management expand

your visibility options
