Replacing the fan tray
The Brocade devices cooling fans use pull configuration to move the air from the front to the back
of the device.
The fans in the Brocade devices include six four-speed fans that operate at low speed, medium
speed, medium-high speed, and high speed based on the ambient temperature and configured or
default temperature thresholds. All fans operate simultaneously at the same speed. If a single fan
fails within the assembly, the fan tray should be replaced. The fan tray is hot swappable.
If a Brocade device remains operational during a fan tray replacement, the procedure must be
completed within 30 seconds.
NOTE
Fan trays are hot swappable. Hot swapping fan trays should be done within 30 seconds so the unit
will continue to function correctly without any fans. However, Brocade recommends that you
disconnect the power supply from AC or DC power before installing or removing the fan tray.
