Fiber Optic Devices

An optional slide-in 1000BASE-SX, 1000BASE-LX or 100BASE-FX module, or

1000BASE-X transceiver may be used for backbone and long distance connections.

A 1000BASE-SX, 100BASE-LX, or 1000BASE-X transceiver may also be for

connecting to a high-speed server.

Each single-mode fiber optic port requires 9/125 micron multimode fiber optic

cabling with an SC connector at both ends. Each multimode fiber optic port requires

50/125 or 62.5/125 micron multimode fiber optic cabling with an SC connector at

both ends.

Warning: This switch uses lasers to transmit signals over fiber optic cable. The lasers are

compliant with the requirements of a Class 1 Laser Product and are inherently

eye safe in normal operation. However, you should never look directly at a

transmit port when it is powered on.

1. Remove and keep the SC port’s rubber plug. When not connected to a fiber

cable, the rubber plug should be replaced to protect the optics.

2. Check that the fiber terminators are clean. You can clean the cable plugs by

wiping them gently with a clean tissue or cotton ball moistened with a little

ethanol. Dirty fiber terminators on fiber optic cables will impair the quality of the

light transmitted through the cable and lead to degraded performance on the

port.

3. Connect one end of the cable to the SC port on the switch and the other end to

the SC port on the other device. Since SC connectors are keyed, the cable can

be attached in only one orientation.

4. As a connection is made, check the Activity LED on the switch’s front panel for

the corresponding module to be sure that the connection is valid.
