NOTE
Do not disassemble any part of the power supply or fan assembly. There are no user-serviceable parts
inside the power supply and fan assembly.
CAUTION
Changes or modifications made to this device that are not expressly approved by the party
responsible for compliance could void the user's authority to operate the equipment.
NOTE
If you are using two power supply and fan assemblies, maintain both power supply and fan assemblies
in operational condition to provide redundancy.
The cooling system relies on pressurized air; if you are using redundant power supply and fan
assemblies, do not leave either of the power supply and fan assembly slots empty longer than two
minutes when the Brocade 6505 is operating. If one power supply and fan assembly fails, leave the
power supply and fan assembly in the Brocade 6505 until it can be replaced.
CAUTION
If you do not install a module or a power supply in a slot, you must keep the slot filler panel in
place. If you run the chassis with an uncovered slot, the system will overheat.
Removing and replacing a power supply and fan assembly
The Brocade 6505 fans are fixed inside the combined power supply and fan assembly to provide
necessary airflow to cool the entire system. There are two fans located in each power supply and fan
assembly. The system software sets fan speed and measures the speed through the tachometer
interface.
The following table describes the power supply and fan assembly status LED colors, behaviors, and
actions required, if any.
