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. METRO-
bility offers FX modules with SC, ST and MT-RJ multimode connectors in
addition to SC singlemode connectors which support network segments up to 15 or
40km. For added versatility, all FX modules include two user-selectable controls to
configure the port’s duplex mode and to set the backpressure/flow control.
By breaking up the collision domain and multiplying network performance, the
Lancast CenturySwitch delivers the ideal solution for easing network congestion
problems on existing shared-hub networks. Use the CenturySwitch to increase
overall network transmission speed and to improve efficiency to accommodate
high-bandwidth applications such as imaging, multimedia and CAD/CAM.
The CenturySwitch includes an universal internal power supply and is perfect for
stand-alone or rackmount use in any office environment.
