Chapter 4: Installing the Switch
powered on.
WARNING: When selecting a fiber SFP device, 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 SFP transceiver.
Step 1. Remove and keep the LC port’s rubber plug. When not connected to a fiber cable, replace the rubber plug to protect the optics.
Step 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.
Step 3. Connect one end of the cable to the LC port on the switch and the other end to the LC port on the other device. Since LC connectors are keyed, the cable can be attached in only one orientation.

Step 4. As a connection is made, check the Link LED on the switch corresponding to the port to be sure that the connection is valid.
The fiber optic ports operate at 1 Gbps. The maximum length for fiber optic cable operating at Gigabit speed will depend on the fiber type as listed in Section 4.12,
4.10 Connectivity Rules
NOTE: When adding hubs to your network, switches break up the path for connected devices into separate collision domains, so you don’t include the switch or connected cabling in your calculations for cascade length involving other devices.
