APPENDIX C
Cable Pinouts
This appendix describes pinout information for 10/100/1000BaseT ports, console and the RJ-45 to DB-9
ports, and the Management 10/100/1000 Ethernet port, and includes the following sections:
• 10/100/1000BaseT Connectors, page C-1
• Console Port (RJ-45), page C-2
• RJ-45 to DB-9, page C-3
• MGMT 10/100/1000 Ethernet Port, page C-3
• Gigabit and Fibre Channel Ports, page C-4
10/100/1000BaseT Connectors
The adaptive security appliance supports 10/100/1000BaseT ports. You must use at least a Category 5
cable for 100/1000baseT operations, but a Category 3 cable can be used for 10BaseT operations.
The 10/100/1000BaseT ports use standard RJ-45 connectors and supports MDI and MDI-X connectors.
Ethernet ports normally use MDI connectors and Ethernet ports on a hub normally use an MDI-X connector.
Use an Ethernet straight-through cable to connect an MDI to an MDI-X port. Use a cross-over cable to
connect an MDI to an MDI port, or an MDI-X to an MDI-X port.
Figure C-1 shows the 10BaseT and the 100BaseTX connector (RJ-45).
