Appendix F
Connectors and Pin Assignments
This appendix describes the BayStack 450 switch port connectors and pin
assignments.
This appendix covers the following topics:
• “RJ-45 (10BASE-T/100BASE-TX) Port Connectors” (page F-1)
• “MDI and MDI-X Devices” (page F-2)
• “DB-9 (RS-232-D) Console/Comm Port Connector” (page F-5)
RJ-45 (10BASE-T/100BASE-TX) Port Connectors
The RJ-45 port connectors (Figure F-1) are wired as MDI-X ports to connect end
stations without using crossover cables. (See “MDI and MDI-X Devices” on
page F-2 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.
