Scalable, flexible, cost-effective.
This switch system is more than just tough. It's extremely versatile with a range of interface options. The modular design gives you the ability to add the right quantity, speed, and type of interfaces you need. If your needs change in the future, you can just swap out modules. Choose from copper and fiber modules, including a 10-GbE SFP+ module.

Ensure 100% uptime.
With dual power supplies, the switch is designed for redundancy. Set it up in a ring topology. If a link fails, the switch automatically falls over in less than 30 milliseconds. The switch is also compatible with redundant switches from other manufacturers.

Very manageable.
This switch includes extensive management software enabling you to manage it locally or remotely eliminating costly and time-consuming truck rolls. Software includes: SNMP, QoS, VLAN, IGMP Snooping, SMTP Client, DHCP; MRP, MSTP, and more.

SFP customization.
By plugging in different SFPs, you can customize the switch to the distances and connectors you need. Use the LFP400 Series SFP transceivers with all modules except the LE2731C. Use the SFP+ transceivers (LSP420 Series) with the 10-GbE module (LE2731C).

The Black Box LGB304A is a compact gigabit Ethernet switch with four 10/100/1000 Mbps RJ45 ports. Typical applications include LAN connectivity for small workgroups. The switch is ideal for mobile teams such as auditors that require a small, portable switch to expand port counts. The switch can be powered from a USB port or from the included power adapter. The switch delivers line rate, non blocking throughput. Ports are autonegotiating half/full duplex and include LED indicators to view port status. This unmanaged switch is plug and play and does not require any configuration.

This high-speed Gigabit Ethernet switch is ideal for building small workgroups as well as small- or home-office networks. It's also a good choice for remote- and branch-office installation. Its fast 1000-Mbps ports provide fast file transfer, yet automatically adapt to older 10- and 100-Mbps devices, enabling you to mix and match different network speeds on the same network. All ports support Auto MDI/MDI-X, so you never have to worry about whether you need a straight-pinned or crossover cable.

This capable Layer 2+ switch offers 8 autosensing 10-/100-/1000-Mbps RJ-45 Ethernet ports, plus 2 dual-media ports, each of which consists of one 100-/1000-Mbps RJ-45 port plus a 100-/1000-Mbps SFP port. The dual-media ports can be used either as a normal UTP Ethernet port for copper connections or adapted to fiber through the use of an SFP.

You can also bundle multiple ports to create a single high-bandwidth port using 802.3ad LACP aggregation. The switch supports up to 2 ports per group and up to 5 groups total. Combine Gigabit ports, for instance, to create a multilink trunk for load sharing. It's especially beneficial in switch-to-switch cascading applications where you require higher full-duplex speeds.

The switch supports 1024 multicast groups. Broadcast/multicast/ unicast storm control enables you to restrict excess traffic on your network. Plus it has IGMP (v1/v2/v3) for limiting bandwidth-heavy multicast traffic.

Very manageable

The switch is fully managed, supporting SNMP version 1, 2c, and 3. The embedded RMON software agents support RMON groups 1 (history), 2 (statistics), 3 (alarms), and 9 (events). It also includes a DHCP server to assign IP to DHCP clients.

The integral Web server enables Web-based management via Web browser. This GUI interface enables switch configuration, system dashboard, maintenance, and monitoring. In addition, a Device Management System provides topology and map view graphical monitoring, traffic monitoring, and troubleshooting.

The wide range of management and support features also includes dual image, port mirroring, LLDP, sFlow®, UPnP®, IPv6, SSH, RADIUS, DHCP Client/DHCPv6 Client, SNTP, cable diagnostics, ping, syslog, and Telnet client with SSH security.

Support for VLAN and QoS

The switch supports up to 4000 simultaneous VLANs for isolating guest traffic from your critical corporate network traffic. You can segment traffic with port-based, 802.1Q tag-based, or MAC-based VLANs.

Plus, you can also program higher-layer classification and prioritization for reliable Quality of Service (QoS).802.1p Layer 2 QoS enables prioritization of time-sensitive applications, such as VoIP and video.

Highly Secure

You get enterprise-class security features, too. In addition to the switch's VLAN support, it boasts 802.1X port-based network access control for authenticating devices connecting to your network. In addition, the switch supports SNMPv3 cryptographic security, SSH, and SSL for remote management via a connection that encrypts the packet content at each session. Plus, you can set up a guest VLAN that enables visitors to access the Internet without also giving them access to the corporate network. By using its extensive ACLs (up to 256 entries total), you can keep guests or unauthorized users from accessing sensitive portions of your network.
