Figure 4-5.    Inserting an SFP Transceiver into the Slot 

 

To install an SFP transceiver, do the following: 

1. Use your cabling requirements to select an appropriate SFP transceiver type. 
 

2. Insert the transceiver with the LC connector facing outward and the slot connector facing 
down.  

Note: SFP transceivers are keyed so they can only be installed in one orientation. 
 

3. Slide the SFP transceiver into the slot until it clicks into place. 
 

1. If the stacking ports are connected, the SFP port will be disabled. 
2.  SFP transceivers are hot-swappable. You do not need to power off the switch before 

installing or removing a transceiver. However, you should always first disconnect the 
network cable before removing a transceiver. 

 

Each device requires an unshielded twisted-pair (UTP) cable with RJ-45 connectors at both ends. 
For 1000BASE-T connections, Category 5, 5e or 

better cable is required; for 100BASE-TX 

connections, Category 5 cable is required; for 10BASE-TX, Category 3,4, or 5 cable can be used. 
 

The RJ-45 ports on the NCT240 modules support automatic MDI/MDI-X operation, so you can use 
standard straight-through twisted-pair cables to connect to any other network device (PCs, 

servers, switches, routers, or hubs). 
 

Note:  Auto-negotiation must be enabled for automatic MDI/MDI-X pin out configuration. See 

Appendix B for further information on cabling.
