Fiber Optic Devices
An optional slide-in 1000BASE-SX, 1000BASE-LX, or 1000BASE-LH SFP
transceiver may be used for backbone or remote connections, or for connecting to a
high-speed server.
Each single-mode fiber optic port requires 9/125 micron single-mode fiber optic
cabling with an LC connector at both ends. Each multimode fiber optic port requires
50/125 or 62.5/125 micron multimode fiber optic cabling with an LC 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 any protective port covers. When not connected to a fiber
cable, the 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 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 LC port on the switch and the other end to
the port on the other device. Since LC connectors are keyed, the cable can be
attached in only one orientation.

4. As a connection is made, check the green Link LED on the switch
corresponding to the port to be sure that the connection is valid.
