3. As each connection is made, the Link LED (on the switch) corresponding to
each port will turn on green to indicate that the connection is valid.
How to Connect to SFP Fiber Optic Ports
The switch provides four slots for SFP-compliant fiber-optic transceivers.
Note that all 1000BASE fiber optic ports operate at 1 Gbps full duplex.
Note: The length of fiber optic cable for a single switched link should not exceed
the relevant standards specified in this section. However, power budget constraints
should also be considered when calculating the maximum fiber optic cable length
for a particular link.
Note: Maximum distances may vary for different SFP vendors.
Connection Procedure 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.
