Connectors and pin assignments

This appendix describes the BayStack 420 Switch port connectors and pin assignments.

RJ-45 (10BASE-T/100BASE-TX) port connectors

The RJ-45 port connectors (Figure 84) are wired as MDI-X ports to connect end stations without using crossover cables. (See “MDI and MDI-X devices” on page 196 for information about MDI-X ports.) For 10BASE-T connections, use Category 3 (or higher) UTP cable. For 100BASE-TX connections, use only Category 5 UTP cable.
