The following sections describe how to get your Switch 4500
powered-up and ready for operation.
Use the following sequence of steps to power-up the Switch.
1 Plug the power cord into the power socket at the rear of the Switch.
2 Plug the other end of the power cord into your power outlet.
The Switch powers-up and runs through its Power On Self Test (POST),
which takes approximately one minute.
During the Power On Self Test, all ports on the Switch are disabled and
the LEDs light. The PWR LED will flash green during the POST.
When the POST has completed, check the PWR LED to make sure that
your Switch is operating correctly. Table 10 shows possible colors for the
LED.

disconnecting the power cord.
WARNING: The Switch 4500 PWR supports Power over Ethernet on
10/100 ports only. These ports should only be used for Ethernet wiring
