EX-3524/EX-3548 Layer 2 Gigabit Ethernet PoE/PoE+ Switch
2.
Attach the other end to an available port on the switch. Ensure each twisted pair cable does not exceed
100 meters (328 ft) in length.
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.
3.4.5 Connecting to SFP Ports
The switch provides four ports for SFP-compliant fiber-optic transceivers. All 1000BASE fiber optic ports operate
at 1 Gbps full duplex. The 100BASE fiber optic ports operate at 100 Mbps full duplex.

NOTE
The length of fiber optic cable for a single switched link should not exceed the
relevant specified standards. However, power budget constraints should also be
considered when calculating the maximum fiber optic cable length for a a particular
link. Maximum distances may vary for SFP vendors.
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. 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.
