Looking to grow your office network the smart way? The Eco Fanless Gigabit Smart Switch enables you to connect Gigabit Ethernet, Fast Ethernet, or Ethernet devices. You can populate two switch ports with the optional Small Form Factor Pluggable (SFP) Optical Transceivers and connect to fiber-based Gigabit Ethernet. The switch offers the versatility you need in growing your network the green way. And it offers browser-based management capability plus Quality of Service (QoS), port mirroring, and tag- and port-baed VLAN.

Web smart.

The switch has the easy-to-use management capabilities network administrators need. Simply access a switch via your Web browser and log on to monitor, configure, and control each port’s activity. It also supports SNMP V1/V2c. In addition, the switch supports Quality of Service (QoS), port mirroring, and tag- and port-based VLAN.

Put some fiber in your data diet.

The last two ports give you the option to connect to fiber-based Gigabit Ethernet. Add one of our Small Form Factor Pluggable (SFP) Optical Transceivers (sold separately) for short-, medium-, or long-distance fiber-optic connections. The transceivers are hot-swappable and available in multimode and single-mode versions. They are Layer 1 devices, which makes them transparent to your application.

Keeping it real-time.

This switch not only supports Layer 2 802.1p Priority Queue control, but it also provides enhanced QoS support for real-time applications like Voice over IP (VoIP). And it supports Layer 4 TCP/UDP port and ToS classification.

Mirror, mirror on the port.

Port mirroring copies traffic from one specific port to a second target port. This mechanism enables you to track network errors or abnormal packet transmissions without interrupting the flow of data. All ports on the switch are capable of port mirroring.

The traffic report.

You can use VLAN to isolate traffic between different users and thus provide better security. Plus VLAN enables you to confine the broadcast traffic to the same VLAN broadcast domain to boost network performance. IGMP V1/V2 snooping limits bandwidth-intensive multicast traffic to only the requesters.

Life in the fast lane.

The switch enables you to combine ports to create a multilink, load-sharing trunk. Port trunks are useful for switch-to-switch cascading, which provides very fast, full-duplex speeds for high-volume communications. With this switch, you can set up to 12 ports per trunk. This switch supports up to 8 trunking groups. All ports are autosensing for speed and auto-negotiating for duplex. The switch’s Auto MDI/MDI-X feature means you never need a crossover cable. Furthermore, the switch supports IEEE 802.x flow control for full-duplex mode and collision-based backpressure for half-duplex mode. *NOTE: Combo ports support both RJ-45 and SFP interfaces, but only one can be active. To add fiber-based Gigabit Ethernet connections to the switch’s dual-media ports, order:
