Express Ethernet
Switches.
These well-engineered machines provide dedicated high­speed workgroups, plus they improve network performance and keep data moving freely and quickly.
Express Ethernet Switches enable you to put a full wire-speed switch right into a network without making a large investment. Plus they’re available in a wide variety of port options, from a 2-port model for small network extension to a 24-port switch with optional fiber uplink for mid-sized networks.
Each switch provides true Layer 2 nonblocking switch architecture and a store-and-forward switching engine. With Layer 2 switching, you get the speed to handle lots of network data. The store-and-forward engine checks the integrity of each data packet and ensures accurate throughput.
All Express Ethernet Switches have an autosensing power supply that adapts to worldwide voltages. A crossover switch makes uplinking to other switches or hubs easy. Extensive LEDs provide port status.
All RJ-45 ports operate at 10/100 Mbps in half- or full-duplex mode. The fiber ports are for 100-Mbps connections in either half- or full-duplex mode.
10-/100-Mbps Copper (LB9108A-R2, LB9019A-R4, LB9020A-R3)
These switches feature 8, 16, or 24 autosensing 10-/100-Mbps RJ-45 ports. They’re perfect for rapid, inexpensive network expansion or building workgroups. The autosensing ports adjust to the speed and duplexity of each port automatically. All ports have auto MDI/MDI-X.
The 8-port model supports 16,384 MAC address entries to support large numbers of end users. It’s housed in a compact, sturdy enclosure suitable for desktop use or wallmounting.
The 16- and 24-port switches support 2048 MAC addresses with address filtering on all ports.
2-Port Express Ethernet Switches, Copper and Fiber (LB9002A-SC-R3, LB9002A-ST-R3)
These compact 2-port switches divide a network into a 10-/100-Mbps copper segment and a 100-Mbps fiber segment.
The 2-port switches are ideal for adding a 100-Mbps fiber island to your existing network or for extending a network long distances over fiber optic cable. To handle the heavy traffic load associated with this sort of network link, the 2-port switches support 8192 MAC address entries.
Choose from ST

or SC connectors on the 100BASE-FX side. Each switch features automatic MDI-X for linking to another device. The switches can be wallmounted or used on the desktop.
5-Port Express Ethernet Switch (LB9005A-FO-R2)
This compact copper plus fiber 5-port switch is ideal for adding small workgroups to your network. The single fiber port serves as an uplink to your network. Four 10/100 autosensing copper ports feature auto MDI/ MDI-X, making it easy to connect workstations without fuss. The switch supports 2048 MAC addresses.
The compact chassis is only about six inches wide so you can it tuck in behind a PC. You may also mount it on any horizontal or flat surface.
8-Port Express Ethernet Switches (LB9006A-SC, LB9006A-ST, LB9021A–LB9022A, LB9007A-SC-R3, LB9007A-ST-R3)
The 8-port switches are good for integrating 100-Mbps fiber into your existing 10-/100-Mbps network. The extra distance from fiber means you can extend network segments up to 1.2 miles (1.9 km). The switches support 1024 MAC address entries.
The LB9006A-SC, LB9006A-ST, LB9021A, and LB9022A models provide DIP switches for controlling port operation manually. For greater versatility, the LB9007A-R3 models have a console port that enables you to control ports and set up port-based VLANs and trunking.
Both LB9007A-R3 models support management. The management type is an ASCII console port (cable included) that provides access to a text-based menu. The menu permits basic configuration of port parameters (such as changing speed or duplex settings), and has a proprietary method for assigning the ports into VLAN and Port-Trunking groups. The LB9007A-R3 models also feature auto MDI/MDI-X.
The LB9006A-SC, LB9006A-ST, LB9021A, and LB9022A models can be rackmounted (hardware is included). The LB9007A-R3 models are intended for desktop use; if you wish to rackmount them, contact Tech Support for the appropriate hardware.
10-/100-Mbps Copper, 100-Mbps Fiber, Modular (LB9017A-R4, LB9024A-R2) and Optional Fiber Uplink Modules (LB9017C-SC-R2, LB9007C-ST-R2)
These Express Ethernet Switches feature 16 or 24 auto­sensing 10-/100-Mbps RJ-45 ports. They’re an economical way to quickly expand your 10BASE-T/100BASE-TX network with the option of adding a fiber uplink later if you need it.
Although the switches are easy to set up, they offer powerful features to help you control heavy network loads. The 2048 MAC address table handles a large number of end users.
