2.7 Making Fiber Connection
The dual-speed SFP slot must be installed with an SFP fiber transceiver for making fiber connection. Your
switch may come with one SFP transceiver pre-installed when it is shipped.
Installing SFP Fiber Transceiver
To install an SFP fiber transceiver into SFP slot, the steps are:
1. Turn off the power to the switch.
2. Insert the SFP fiber transceiver into the SFP slot. Normally, a bail is provided for every SFP transceiver.
Hold the bail and make insertion.
3. Until the SFP transceiver is seated securely in the slot, place the bail in lock position.
Connecting Fiber Cables
LC connectors are commonly equipped on most SFP transceiver modules. Identify TX and RX connector
before making cable connection. The following figure illustrates a connection example between two fiber
ports:
Make sure the Rx-to-Tx connection rule is followed on the both ends of the fiber cable.
Network Cables
Multimode (MMF) - 50/125, 62.5/125
Single mode (SMF) - 9/125
Port Speed Configuration
There are three options for configuring port speed via software for the SFP Port. The options are:
Port Mode
Auto
100Mbps FDX
1Gbps FDX
