Follow these steps to connect cables to SFP transceiver ports:
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.
WARNING: When selecting a fiber SFP device, considering safety, please make sure that it can function at a temperature that is
not less than the recommended maximum operational temperature of the product. You must also use an approved Laser Class 1
SFP transceiver.
1.
Remove and keep the fiber 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 small amount of 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 SFP port on the switch and the other end to the SFP port on the other device. Since SFP
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 to be sure that the connection is valid.
NOTE:
Be sure to secure cables properly and route them away from the switch without exceeding the minimum bending radius for
fiber cables (typically a few inches). Use cable ties to bundle cables together and secure coiled loops of excess cable. Do not let
cables hang free supporting their own weight or pull in any way that puts stress on the connectors.
