Installation guide

24 EX-3524/EX-3548 Layer 2 Gigabit Ethernet PoE/PoE+ Switch
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 validate the connection is valid.
NOTE Ensure cables are properly secured 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.
