LAN extension and the other LB400A is configured as the (R) Remote unit at the other end. The LB400A is configured as a L or R via the switch on the rear panel. These units can automatically forward LAN broadcasts, multicasts, and frames across a 2-wire voice-grade twisted-pair link. - Page 8 HIGH SPEED ETHERNET EXTENDER Figure 1. Typical application The pair of LB400A models work together to create a transparent extension between two peered Ethernet LANs. Figure 1 shows a typical point-to-point application.

flammability, and mechanical serviceability. CAUTION The LB400A does not have a power switch, so it powers up as soon as it is plugged in. An external AC or DC power supply is available separately. This connection is made via the barrel jack on the rear panel of the LB400A. -
Page 13: Configuration
HIGH SPEED ETHERNET EXTENDER 3. Configuration The LB400A has eight DIP switches for configuring the unit for a wide variety of applications. This section describes switch locations and explains the different configurations. Using a small flat-tip screwdriver, remove the protective cover located on the underside of the Ethernet Extender (see Figure 5). -

12 to verify that the unit is connected to the appropriate power source. 4.2 Front Panel LED Status Monitors The LB400A features five front panel LEDs that monitor power, the Ethernet sig- nals, and the Line connection. Figure 7 on page 17 shows the front panel location of each LED. - Page 18 HIGH SPEED ETHERNET EXTENDER Table 8: Front panel LED description Description Power Solid GREEN to indicate the unit is powered on. Link Solid GREEN (ON) to indicate that the end-to-end link between the LB400As is established. The Link LED is OFF when the link is down. Ethernet Solid GREEN indicates that 10/100Base-T Ethernet link has been established.
