Product Overview Thank you for choosing the Lancast CenturySwitch. Designed to meet the needs of today’s growing networks, the Lancast 8-Port CenturySwitch is a compact, low-cost switch featuring a unique replaceable port module. The standard unit provides eight auto-negotiating 10/100 TX ports including one modular port with two connectors to support either a crossover or parallel connection. The TX interface may be replaced by an optional 100Base-FX module.

3 Connect to the Network The Lancast CenturySwitch is compatible with both 10Base-T and 100Base-TX devices. Network connections are made by simply plugging the cables into the RJ-45 port connectors on the front panel as shown in the figure below. Each port supports a maximum segment length of 100 meters over Category 5 UTP cables for 100Base-TX segments and Category 3, 4 or 5 UTP cables for 10-Base-T segments.
Proceed to Step 5 if you are not using a fiber module. The standard 10/100 TX module installed in the CenturySwitch may be replaced by a 100Base-FX module. Refer to the listing inside the front cover for all available options. 1 2 3 Set the Backpressure Jumper Prior to installing the fiber module, you must set the flow control/ backpressure jumper labeled “JP2” on the printed circuit board. See the diagram below for its location. • Connect jumper pins 1 and 2 to enable backpressure.
Connect to the Network The 3508-04-F and 3508-07-F modules provide a pair of singlemode SC connectors. The 3508-04-F supports a maximum segment length of 15km and the 3508-07-F supports a maximum segment length of 40km. 10/100 Ethernet Switch ® CenturySwitch ® Module Port 8 1 2 3 4 5 6 7 8 1x 2x 3x 4x 5x 6x 7x TX Link/Act RX 100Mbps Power FDX 3508-11 100BASE-FX HDX FDX The 3508-03-F and 3508-05-F modules provide a pair of multimode SC and ST connectors, respectively.

User Guide This section contains more detailed information regarding the operating features of the Lancast CenturySwitch. LED Operation The functional descriptions of the LED indicators are listed below. The port LEDs report the status of their corresponding ports labeled 1 through 8. LED Name Color Status Function System LED Power Green ON Unit is powered ON. Per Port LEDs Link/Act Green 100Mbps ON Connection with remote device is good. Blinking TX traffic is present.
Troubleshooting Cabling Problems Improper cabling is the primary cause of most network problems, particularly for 100Base-TX and 100Base-FX networks. Use only the specified twisted-pair or fiber optic cables to avoid most cabling problems. • Flat telephone extension cables, or Category 3 wires, are not the same as Category 5 twisted-pair cables and will not function on Fast Ethernet networks.
• The mode (half duplex or full duplex) and speed (10Mbps or 100Mbps) of the NIC setting must match the mode and speed setting of the corresponding port of the switch. For NWay Auto-Negotiation setting, both link partners will adjust to the highest allowable speed and mode operation. Other Problems Other specific problems may be diagnosed by using the LEDs as described below.
