Installation
30
Instruction Manual - NXA-ENET8-POE+
Perform the following steps to install an SFP transceiver:
1.
Consider network and cabling requirements to select an appropriate transceiver type that is also compatible with the switch
transceiver support.
2.
If the SFP slot is covered with a rubber protective cap, remove the cap and keep it for later replacement.
3.
Insert the transceiver with the optical connector facing outward and the slot connector facing down. Note that SFP
transceivers are keyed so they can only be installed in the correct orientation.
4.
Slide the transceiver into the slot until it clicks into place. If you do not immediately connect a cable to the port, use a rubber
protective cap to keep the transceiver optics clean.
NOTE:
To remove a transceiver, first disconnect the network cable, then pull the tab to remove the transceiver from the slot.
Connecting to Twisted-Pair Copper Ports
The RJ-45 ports on the switch support automatic MDI/MDI-X pin-out configuration, which enables you to use standard
straight-through twisted-pair cables to connect to any other network device (PCs, servers, switches, routers, or hubs).
The connection requires an unshielded twisted-pair (UTP) or shielded twisted-pair (STP) cable with RJ-45 connectors at both ends..
Copper Cabling Guidelines
To ensure proper operation when installing the switch into a network, make sure that the current cables are suitable for 10BASE-T,
100BASE-TX, or 1000BASE-T operation. Check the following criteria against the current installation of your network:
Cable type: Unshielded twisted pair (UTP) or shielded twisted pair (STP) cables with RJ-45 connectors; Category 5, 5e or
better cable for 1000BASE-T connections, Category 5 or better for 100BASE-TX connections, and Category 3 or better for
10BASE-T connections.
Protection from radio frequency interference emissions
Electrical surge suppression
Separation of electrical wires (switch related or other) and electromagnetic fields from data based network wiring
Safe connections with no damaged cables, connectors or shields
