This appendix describes the pinouts of the switch’s cables and connectors.

10BASE-T/100BASE-TX Connectors

Ports 1 and 2 are MDI-X 10BASE-T/100BASE-TX Ethernet ports with
NWay capability, allowing them to automatically detect port speed. The
Uplink port is identical to Port 1x, except that it has an MDI pinout instead.
(You cannot use Port 1x and the Uplink port at the same time.)

Ports 3 through 18 are MDI-X 10BASE-T Ethernet ports.

10BASE-T/100BASE-TX connection requires a twisted-pair cable, at most
100 meters long, with RJ-45 connectors at both ends. You can use shielded
twisted-pair cable or 0.4-0.6 mm (22-26 AWG) 8-wire unshielded twisted-
pair cable for the connection. 100BASE-TX connection requires Category 5
twisted-pair cabling.

The following diagram and table show the standard RJ-45
receptacle/connector and their pin assignments. Numbering of the pins and
contacts shown in the diagram correspond to the entries in the subsequent
table. Only pin/contact signals relevant to the switch are listed.
