Cable Specifications
This section provides specifications for the following Ethernet cables, which you might need to provide:
•
•
Because of the autocrossover (autosensing) function, both straight-through and crossover cables can be used for the Ethernet LAN port.
Ethernet Cable Specifications
Table A-7 provides specifications that apply to both straight-through and crossover Ethernet cables.
