Figure 27
shows the cooling fans.
FIGURE 27
Cooling Fans
The device cooling fans use pull configuration to move the air from the front to the back of the
device.
NOTE
Brocade NetIron CES/CER-4X-RT supports the XNI-CE-2000-FAN pre-installed or as a spare. All other
models support the NI-CE-2000-FAN.
The fans in the 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 and the mean
time to recover (MTTR) is one minute.
The system uses a default or configured temperature threshold associated with it to determine at
which speed the fan should operate.
