All of the Cisco Nexus 2000 Series FEXs are 1 RU high and require 19-inch racks for installation. For
more information about the dimensions and weights of each FEX chassis, its power supplies, and fan
modules, see

Power Supply and Fan Modules

Each FEX chassis supports one or two power modules (one for operations and one for redundancy) and
1, 3, or 4 fan modules (depending on the FEX model). If the chassis has only one power supply, make
sure that there is a blank module (N2200-P-BLNK) installed in the unused power supply slot to preserve
the designed airflow.
Each FEX chassis supports power supply and fan modules that have either port-side intake or port-side
exhaust airflow.
All of the power supply and fan modules in the same chassis must have the same airflow direction and
Caution
the cold air intake for the chassis must be located in a cold aisle or else the switch can overheat and shut
down.
Port-side intake modules have red coloring and port-side exhaust modules have blue coloring. Power
supply coloring is displayed on the module release latches, and fan module coloring is displayed as either
a stripe on the front of the module or as the color of the module handle.
Some older power supply and fan modules use black stripes for port-side intake airflow and no stripe for
Note
port-side exhaust airflow.
You can hot swap a power supply module as long as there is another power supply module functioning
in the chassis. You can hot swap a fan module in a chassis with multiple fan modules as long as the other
fan modules are installed and functioning. You can hot swap a fan module in a chassis with a single fan
module as long as you replace it within 60 seconds.
