follow these steps to connect to a power source:

    step 1 connect one end of the supplied ac power cord to the power connector on a switch rear panel. see figure c-2.

    step 2 connect the other end of the power cable to a grounded ac outlet.

    if you are connecting the switch to a cisco redundant power system (rps), refer to the documentation that shipped with your rps.

    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. 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.

    if you started the terminal emulation program before you powered on your switch, the pc or terminal displays the bootloader sequence. you need to press enter to display the setup program prompt.
