Step 8
When you are ready to power up the switch, remove the safety flag and lockout devices from the PoE
expansion module DC circuit and turn on the power to power up the module.
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.
For instructions on how to apply power to a switch that is connected to a power converter, see the
Note
"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 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.
Note
Both the AC-input and the DC-input power supplies can support only two ports configured as PoE+
ports. If you want to operate all four PoE expansion module ports as PoE+, you must connect the
expansion module directly to the site's source DC.
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
Do not overtighten the terminal block screws. The torque on the screws should not exceed
2.2 in-lb (0.25 Nm).
