Caution: 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 cover. When not connected to a fiber
cable, the rubber cover 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 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 Link LED on the switch corresponding to
the port to be sure that the connection is valid.
Note: If you use the optional SC-ST Converter, be sure to connect the converter’s Tx
(Rx) port to the Rx (Tx) port on the other device.
1000BASE-SX, 1000BASE-LX and 1000BASE-LH fiber optic ports operate at
1 Gbps full duplex, with auto-negotiation of flow control. 100BASE-FX connections
operate at 100 Mbps, full duplex, with auto-negotiation of flow control.
