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.
3.4.2 Connecting Twisted-Pair Cables
The RJ-45 ports on the switch support automatic MDI/MDI-X pinout 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.
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
NOTE
To remove a transceiver, disconnect the network cable then pull the tab to remove the
transceiver from the slot.
