10. Verify that the device is powered on and POST is complete (all power LED
11. Verify that all components are functioning correctly by checking their LEDs. If
12. Perform the following procedures in order to complete this installation:
Synchronizing airflow direction on WWN cards
An airflow direction mismatch may occur if the airflow direction, nonport-side
intake (NPI) or nonport-side exhaust (NPE), for installed fan and power supply
assembly FRUs does not match airflow direction set on new WWN cards shipped
with replacement chassis.
You can check airflow direction for fans in fan and power supply assemblies
installed in device with airflow direction set on WWN cards by entering the
chassisShow command. Airflow direction of fans and power supplies displays as
"Fan Direction" under each fan or power supply unit. System airflow direction
displays as "System Airflow" under the WWN card unit.
If the chassisShow command or RASlog messages indicate a mismatch between
system airflow direction and airflow direction of fan in power supply or fan
assemblies refer, to "Configuring airflow direction on WWN cards" on page 157 for
instructions on configuring correct airflow direction on WWN cards.
Note: Changing chassis airflow allows you to synchronize established chassis
airflow direction from installed fan and power supply assemblies with airflow
direction configured on WWN cards. This procedure may need to be used after
replacing WWN cards. This procedure must be performed when replacing the
chassis, as replacement chassis are shipped with new WWN cards installed and
airflow direction is not configured on these cards. This procedure is not supported
for any other purpose.

The device performs a power-on self-test (POST). The POST takes a minimum
of three minutes and is complete when LED activity returns to the standard
state. The power supply LED will light green when power is applied. Note
that after one power supply is plugged into AC power, LEDs on the
remaining installed power supplies will flash green until they also have full
power.
indicators on the blades should be a steady green).
the LEDs do not indicate correct operation, try reinstalling the corresponding
