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.
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: UTP or 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
3.4.3 Cable Requirements
All Category 5 UTP cables that are used for 100BASE-TX connections should also work for 1000BASE-T, providing
that all four wire pairs are connected. However, it is recommended that for all critical connections, or any new cable
installations, Category 5e (enhanced Category 5) or Category 6 cable should be used. The Category 5e and Category
6 specifications include test parameters that are only recommendations for Category 5. Therefore, the first step in
NOTE To remove a transceiver, disconnect the network cable then pull the tab
to remove the transceiver from the slot.
