Cabling Specifications


This appendix provides cable pinout descriptions for the DistributedDirector 4700-M.


Note   All pins not listed are not connected.


Following are the signal summaries contained in this appendix:

EIA/TIA-232 console cable

EIA/TIA-232 auxiliary cable

Ethernet (AUI) cable

RJ-45 (10BaseT) cable

Token Ring port

The cables available from Cisco meet FCC part 15J Class A requirements and Verband Deutscher Electrotechniker (VDE) 0871 Limit B levels. When constructing your own cables, refer to the appropriate documentation regarding interference considerations and cable length limitations.

EIA/TIA-232 Console and Auxiliary Port Pinouts

Refer to Table B-1 when assembling an EIA/TIA-232 console cable or auxiliary port cable for the Cisco DistributedDirector 4700-M.
