Switch Installation
Running POST
When the switch powers on, it automatically initiates a POST. The POST runs a series of tests that verify
that the switch functions properly and ensures that it is ready to install. To test the switch, follow these
steps:

Applying Power to 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
If you have installed a PoE expansion module (either IEM-3000-4PC or IEM-3000-4PC-4TC) to the
switch, you must attach DC power directly to the expansion module. DC power can be either from site
source DC (verify that source DC power meets the power input requirements of the expansion module)
or from a separate DC-power supply (PWR-IE65W-PC-DC or PWR-IE65W-PC-AC). If your switch
configuration consists of two PoE expansion modules, you must connect each PoE expansion module to
a separate power supply. For instructions on how to connect the DC-input power supply to the PoE
expansion module, refer to the Cisco IE 3000 65 W DC-Input Power Supply Installation Note available
on cisco.com. For instructions on how to connect the AC-input power supply to the PoE expansion
module, refer to the Cisco IE 3000 65 W AC-Input Power Supply Installation Note available on
cisco.com.
Verify POST Results
When you power on the switch, it automatically begins 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
turn 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
