before installing the switch in a rack, on a wall, or on a table or shelf, you should power the switch and verify that the switch passes post.

    if your configuration has an rps, connect the switch and the rps to the same ac power source. see the “power connectors” section on page 1-12, and see the cisco rps documentation for more information.

    always put the rps in standby mode when you are connecting devices to it and in active mode during normal operation.

    to power on the switch, connect one end of the ac power cord to the ac power connector on the switch, and connect the other end of the power cord to an ac power outlet.

    attach only the cisco rps 675 (model pwr675-ac-rps-n1=) to the rps receptacle. statement 100c

    as the switch powers on, it begins the power-on self test (post), a series of tests that runs automatically to ensure that the switch functions properly, and leds can flicker during the test. post lasts approximately 1 minute. when the switch begins post, the system, rps, status, duplex, and speed leds turn green. the system led blinks green, and the other leds remain solid green.

    when the post completes successfully, the system led remains green. the rps led remains green for some time and then reflects the switch operating status. the other leds turn off and then reflect the switch operating status. if a switch fails post, the system led turns amber.

    post failures are usually fatal. call cisco systems if your switch does not pass post.

    after a successful post, disconnect the power cord from the switch. install the switch in a rack, on a wall, on a table, or on a shelf as described in the “installing the switch”.
