Identifying Cable Pinouts

This appendix describes pinout information for the 10/100/1000 BaseT ports and the RJ-45 to DB-9 ports,
and the RJ-45 cables for the console port.
This chapter includes the following sections:
• 10/100/1000BaseT Connectors, page A-1
• Console Port (RJ-45), page A-2
• RJ-45 to DB-9, page A-3

10/100/1000BaseT Connectors

The Cisco 170 series 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 support 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 A-1 shows the 10BaseT, 100BaseTX, and 1000BASE-T connector (RJ-45).
