• Enter the power supply side and exhaust out the port side (port-side exhaust airflow)
For port-side intake airflow, the switch must have port-side intake fan and AC power supply modules with
one or more of the following colorings:
• Burgundy coloring on fan modules and AC power supplies
• Green coloring on DC power supplies
• White coloring on 1200-W HVAC/HVDC power supplies (dual-direction airflow power supplies with
their airflow direction set by the fan modules)
For port-side exhaust airflow, the switch must have port-side exhaust fan and AC power supply modules with
one or more of the following colorings:
• Blue coloring on fan modules and AC power supplies
• Gray coloring on DC power supplies
• White coloring on 1200-W HVAC/HVDC power supplies (dual-direction airflow power supplies with
their airflow direction set by the fan modules)
You can plan the positioning of the switch so that its ports are located close to ports on connected devices or
so that the fan and power supply modules are conveniently located in a maintenance aisle, and then order the
modules that move coolant air in the appropriate direction from the cold aisle to the hot aisle.
All fan and power supply modules in the same switch must operate with the same direction of airflow and
the air intake portion of the switch must be located in a cold aisle.
Note
Installing the Chassis in a Two-Post Rack
Before you install the chassis, be sure that the rack is fully secured to the data center floor.
You must attach mounting brackets to the chassis before mounting the chassis.
Attaching Center-Mount Brackets to the Chassis
You need to attach a right-angled bracket to each side of the chassis. This bracket centers the chassis and
secures it in place on a two-post rack.
