5 Chassis LEDs (Beacon [BCN] and Status [STS])
Note USB support is limited to USB 2.0 devices that use less than 2.5 W (less than 0.5 A inclusive of surge
current). Devices, such as external hard drives, that instantaneously draw more than 0.5 A are not supported.
Depending on whether you plan to position the ports in a hot or cold aisle, you can order the fan and power
supply modules with port-side intake or port-side exhaust airflow. To determine the airflow direction of the
modules installed in your switch, see the following table.
Replaceable Modules
Fans
AC power supplies
HVAC/HVDC power supplies
DC power supplies
The fan and power supply modules are field replaceable and you can replace one fan module or one power
supply module during operations so long as the other modules are installed and operating. If you have only
one power supply installed, you can install the replacement power supply in the open slot before removing
the original power supply.
All of the fan and power supply modules must have the same direction of airflow. Otherwise, the switch
Note
can overheat and shut down. If you are installing a dual-direction power supply, that module will
automatically use the same airflow direction as the other modules in the switch.
Caution If the switch has port-side intake airflow (burgundy coloring for fan modules), you must locate the ports
in the cold aisle. If the switch has port-side exhaust airflow (blue coloring for fan modules), you must
locate the ports in the hot aisle. If you locate the air intake in a hot aisle, the switch can overheat and shut
down.
