AKING ETWORK
Caution: This switch uses lasers to transmit signals over fiber optic
1. Remove and keep the 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 or LC port on the switch and
the other end to the SC or LC port on the other device. Since SC and
LC 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.
1000BASE-X fiber optic ports operate at 1 Gbps full duplex, with
auto-negotiation of flow control. 100BASE-FX fiber optic ports operate at
100 Mbps full duplex, with auto-negotiation of flow control.

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.
