2. Check blower assembly status using the fanShow command. The status for each blower assembly displays OK, absent, or faulty. If any of the blower assemblies are absent or faulty, contact HP support to order replacement parts, as necessary. For additional information about the fanShow command, refer to the hp StorageWorks fabric os reference. WWN Card and Bezel The WWN card and bezel are located at the top of the blower assembly side of the chassis. The WWN card provides LEDs for monitoring the health of 16-port cards, CP cards, and power supplies. The WWN card also stores the following information: • The chassis serial number (used when installing software licenses) • The two native IP addresses assigned to the CP card slots • Information for the two logical switches in the HP StorageWorks Core Switch 2/64: - The logical switch names - The logical IP addresses - The logical WWNs The bezel protects the card and identifies each of the LEDs on the WWN card. Together, the WWN card and bezel assembly provide a consolidated view of the LEDs for the CP cards, 16-port cards, and power supplies. If a slot contains a filler panel, the corresponding LEDs on the WWN card are dark. WARNING Although the information stored in the WWN card is also stored in the flash memory of the CP cards, the switch should not be rebooted while the WWN card is uninstalled, as this can cause the switch to boot incorrectly. CAUTION To prevent damage to the electrical components, wear an ESD grounding strap when working with the WWN card. The chassis must be powered down prior to working with the WWN card.

fanShow
command. The status
for each blower assembly displays OK, absent, or faulty. If any of the

WWN Card and Bezel
The WWN card and bezel are located at the top of the blower assembly side
of the chassis. The WWN card provides LEDs for monitoring the health of
16-port cards, CP cards, and power supplies. The WWN card also stores the
following information:
•
The chassis serial number (used when installing software licenses)
•
The two native IP addresses assigned to the CP card slots
•
Information for the two logical switches in the HP StorageWorks Core
Switch 2/64:
–
The logical switch names
–
The logical IP addresses
–
The logical WWNs
The bezel protects the card and identifies each of the LEDs on the WWN
card. Together, the WWN card and bezel assembly provide a consolidated
view of the LEDs for the CP cards, 16-port cards, and power supplies. If a
slot contains a filler panel, the corresponding LEDs on the WWN card are
dark.
WARNING
Although the information stored in the WWN card is also
stored in the flash memory of the CP cards, the switch should not be
rebooted while the WWN card is uninstalled, as this can cause the switch to
boot incorrectly.
CAUTION
To prevent damage to the electrical components, wear an ESD
grounding strap when working with the WWN card. The chassis must be
powered down prior to working with the WWN card.
