FIGURE 14
Rear fan location for PowerConnect B-MLXe-16 routers
At startup, the fans operate at high speed. After a period of time, the management module
changes the fan speed to low.
By default, the router polls the temperature sensor on each module every 60 seconds for a
temperature reading. Depending on the results, the router will:
Leave the fan speed as is
Increase the fan speed
Decrease the fan speed
Shut down a module to prevent damage
If the temperature of a module exceeds specified high temperature thresholds, the system
generates a Syslog message and SNMP trap. The system can also shut down the module if the
temperature exceeds the highest threshold.
You can change default low and high temperature thresholds for modules and fan speeds. Refer to
“Changing temperature thresholds for modules and fan speeds”
on page 107.
The fan control modules include a bi-color LED, which indicates the status of the fans. The router
ships with fan assemblies fully installed. Fan assemblies are hot-swappable, which means you can
remove and replace them without powering down the system.
NIBI-16-FAN-EXH-A high-speed fan assemblies
NIBI-16-FAN-EXH-A high-speed fan assemblies are required for PowerConnect B-MLXe routers when
you install NI-MLX-10Gx8-M, NI-MLX-10Gx8-D, or NI-MLX-1Gx48-T-A modules. PowerConnect
B-MLXe-16 routers ship with high-speed fan assemblies factory installed. Refer to
“Installing
NIBI-16-FAN-EXH-A fan assemblies”
on page 167 for high-speed fan installation instructions.
