This appendix provides cable pinout descriptions for the DistributedDirector 4700-M.
Following are the signal summaries contained in this appendix:
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.
Refer to Table B-1 when assembling an EIA/TIA-232 console cable or auxiliary port cable for the Cisco DistributedDirector 4700-M.
