4. Depending on the WWN card assembly removed, label the assembly with No. 1 for the left-side assembly and No. 2
for the right-side assembly for future reference.
5. Set the WWN card assembly on a static-free surface, such as a grounding pad.
Configuring the Airflow Direction on WWN Cards
All fan and power supply assemblies installed in the chassis must provide the same airflow direction, either nonport-side
intake (NPI) or nonport-side exhaust (NPE), and the airflow must be neutral.
A mismatch of between the system and fan and power supply airflow direction may occur when installing new WWN cards
into an existing chassis with fan and power supply assemblies already installed or when installing fan and power supply
assemblies into a replacement chassis. Replacement chassis are shipped with new WWN cards installed, and the airflow
direction is not configured on these cards.
The system detects the airflow direction of the chassis at system boot based on the airflow direction of installed power
supply and fan assemblies. Normally, if there is a mismatch between airflow direction set on WWN cards and airflow
direction of the installed fan and power supply assemblies, the system will automatically configure the established airflow
direction on the WWN cards, provided
all
installed fan and power supply assemblies have the same airflow direction.
RASLOG messages such as the following will occur during this automatic configuration:
...[HIL-1630], 449, SLOT 1 CHASSIS, INFO, chassis1, Auto-configuring
system airflow direction to Non-portside Exhaust
[HIL-1630], 449, SLOT 1 CHASSIS, INFO, chassis1, Auto-configuring
system airflow direction to Non-portside Intake
If airflow direction for power supply and fan assemblies does not match, WWN cards will not automatically reconfigure and
the fan or power supply assembly with mismatched airflow will fault. In this case, you must replace fan or power supply
assemblies to achieve matching airflow direction for all, and then reboot the system.
Verifying WWN Card Operation
Perform the following tasks to verify operation of the WWN cards:
1. Check the LED indicators on the WWN card bezel, located between the power supplies on the nonport side of the
device. The LED patterns may temporarily change during POST and other diagnostic tests. For information on
interpreting LED patterns, see
.
2. Enter the
errDump
command. This displays the system error log. Refer to the
Brocade Fabric OS Message Reference
Manual
for more information on the messages in this log.
