NOTE
New WWN cards are shipped preinstalled in the replacement chassis. Do not replace the WWN cards in the
replacement chassis with the old WWN cards from chassis that you are replacing. This will result in licensing
and return materials authorization (RMA) issues for your product. The original license will be transferred to the
replacement chassis, based on the license identification (LID) of the new, preinstalled WWN card, through the
RMA process. You should be provided a license for the new chassis through email. If you have not received this,
contact your Brocade support representative.
DANGER
For safety reasons, the ESD wrist strap should contain a series 1 megaohm resistor.
1. Replace the fan assemblies (
).
2. Replace the power supplies or filler panels (
).
3. Replace the control processor (CP) blades (
4. Replace the core routing (CR) blades (
).
5. Replace the port and extension blades or filler panels (
).
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.
7. Verify that the device is powered on and POST is complete (all power LED indicators on the blades should be a steady
green).
8. Verify that all components are functioning correctly by checking their LEDs. If the LEDs do not indicate correct
operation, try reinstalling the corresponding component.
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 the airflow direction set on the new WWN cards
shipped with replacement chassis.
You can the check airflow direction for fans in the fan and the power supply assemblies installed in the device with the
airflow direction set on the WWN cards by entering the
chassisShow
command. The airflow direction of the fans and
the 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 the system airflow direction and the
airflow direction of the fan in the power supply or fan assemblies, see
Configuring the Airflow Direction on WWN Cards
instructions on configuring correct airflow direction on WWN cards.
NOTE
Changing the chassis airflow allows you to synchronize the established chassis airflow direction from the
installed fan and the power supply assemblies with the airflow direction configured on the WWN cards. This
procedure may need to be used after replacing WWN cards. This procedure must be performed when replacing
the director 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.
