Installing an SFP Transceiver
NCT240
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.
Notes:
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.
