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.
