Connector and Cable Specifications

This appendix provides connector and cable specifications for the Cisco 805 router.

Connector Specifications

This section provides pinouts for the following connectors:

Ethernet---Table C-1
Console---Table C-2
Serial---Table C-3
Power---Table C-4

Function 1 in Table C-1 describes how the connector functions when the HUB/NO HUB button is in the HUB (in) position. Function 2 describes how the connector functions when the HUB/NO HUB button is in the NO HUB (out) position.
