Serial Port Pinouts

Local Manager console ports support a DCE pin-out. This includes both the management console port and the serial ports found on option cards.

To connect the Local Manager's serial ports to a managed device with a DTE pin-out, use a straight-through cable.

To connect the Local Manager's serial ports to a managed device with a DCE pin-out (including the console port of another LM), use a rolled cable.
