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. METRObility 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.

Installation Guide
Follow the steps outlined in this section to install and start using your Lancast
CenturySwitch.
Unpack the Lancast CenturySwitch
Check that the following components have been included:

2
• 8-Port CenturySwitch 3508-11
• Rackmounting hardware: 2 mounting brackets, 4 screws
• Power cord
Your order has been provided with the safest possible packaging. Inspect
it carefully. If you discover any shipping damage, notify the carrier and
follow their instructions for damage and claims. Save the original
shipping carton if return or storage of the unit is necessary.
Choose a Location
The CenturySwitch is intended for use in normal office environments and
requires few restrictions on placement.
• Select a location that is within 6 feet of an AC power source and
less than 100 meters from servers, workstations or other connected
devices.
• Do not connect the unit to a power strip.
• Be sure the location allows for adequate ventilation with a
clearance of at least 1/2" on the sides of the unit.
• Be sure the location is as far away as possible from electrical noise
generating equipment such as copiers, electrostatic printers or
other motorized devices.
The CenturySwitch is designed to be mounted in a standard 19-inch
equipment rack. Use the rackmounting hardware included with the unit to
secure the mounting brackets to the unit. Use the separate screws
provided with the equipment rack to mount the unit in the rack. Be sure
that the mounting of the unit does not impose a hazardous condition due
to uneven mechanical loading.
The CenturySwitch can also be installed on a tabletop. For tabletop
installation, select a location with the power and ventilation requirements
cited above.
* #10-32 screw size is recommended.

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. Once power is
applied to the unit, use the individual Link/Act LEDs to verify correct
segment connectivity.

Fixed Ports
The CenturySwitch provides seven fixed RJ-45 ports with connectors for
devices wired crossover. The ports are labeled 1x through 7x. These dualspeed ports are 10/100Mbps auto-sensing and will automatically detect
and operate at the speed of the connected device.
Module Port
Port 8 provides two RJ-45 connectors which support a device wired either
crossover (MDI-X) or parallel (MDI-II).
IMPORTANT: Do not connect devices to both the MDI-X and MDI-II
connectors at the same time. This can damage the unit and void its
warranty.
