Remote Power-Cycling Operation
This feature allows you to remotely power cycle the Catalyst 6500 series switch using any appropriate
third-party relay controller. This eliminates the need for you to have access to the supervisor engine
console or CLI to control power cycling. Table A-40 lists the relay controller box relay type, the
corresponding power supply terminal block positions, and a description of the power-cycling operation.
