Select fan trays and power modules with airflow directions that meet the ventilation requirements
at the installation site. As a best practice, make sure the power modules and fan trays have the
same airflow direction.
•
Do not install fan trays of different models on the same switch.
•
Do not install power modules of different models on the same switch.

Power modules
CAUTION:
When the switch has power modules in redundancy, you can replace a power module without
powering off the switch. Make sure the power module to be replaced is powered off before you
replace it.
IMPORTANT:
As a best practice, use power modules of the same model in 1+1 redundancy for power supply.
