Installing an SFP Transceiver


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

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.

Connecting to the 1000BASE-T and 10/100BASE-TX Interface

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.
