Features & Benefits

High-Density Switch for Workgroups and Backbones

This plug-and-play switch delivers 10/100 Mbps autosensing Ethernet/Fast Ethernet bandwidth for high-density environments. Its integrated 1000BASE-SX port and two Gigabit Ethernet expansion slots provide additional power and plenty of room to grow.

Two expansion slots accommodate 1000BASE-SX or 1000BASE-LX modules for scalability

Full line-rate nonblocking switching performance delivers up to 6.6 Gbps throughput

Support for up to 16,000 MAC addresses handles networks of virtually any size

Multicast filtering using IGMP snooping

Multicast throttling limits broadcasts and multicasts on a per-port basis

IEEE 802.3x flow control on all full-duplex ports to help improve performance and minimize packet loss

Trunking support (multiple parallel active links) on both Fast Ethernet and Gigabit Ethernet

Supports full VLAN implementation
