Figure 4-2. Network Wiring Connections 
Fiber Optic SFP Devices 
An optional Gigabit SFP transceiver (1000BASE-SX, 1000BASE-LX, or 
1000BASE-LH) can be used for a backbone connection between switches, or for 
connecting to a high-speed server. 
Each single-mode fiber port requires 9/125 micron single-mode fiber optic cable 
with an LC connector at both ends. Each multimode fiber optic port requires 
50/125 or 62.5/125 micron multimode fiber optic cabling with an LC connector at 
both ends. 
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 atransmit port when it is powered on. 
1. Remove and keep the LC 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 little ethanol. 
Dirty fiber terminators on fiber optic cables will impair the quality of the light
