Power On the Switch

To apply power to a switch that is directly connected to a DC power source, locate the circuit breaker on
the panel board that services the DC circuit, and switch the circuit breaker to the ON position.
Note For instructions on how to apply power to a switch that is connected to a power converter, see the
"Applying Power to the Power Converter" section on page

Verify POST Results

When you power on the switch, it automatically begins a POST. All LEDs are off for a few seconds, and
then each LED is tested. One at a time, the System, Alarm, Setup, Pwr A, and Pwr B LEDs each briefly
turns green, then red, and then go off. The System LED blinks green as the boot loader verifies the basic
functionality of the processing and memory hardware. Assuming all tests pass, the System LED
continues to blink green as the Cisco IOS software image loads. If the POST fails, the System LED turns
red.
POST failures are usually fatal. Call Cisco Systems immediately if your switch does not pass POST. See
