Installing and removing a power supply

CAUTION:
• Select fan trays and power supplies that have the airflow direction matching the ventilation
requirements at the installation site. As a best practice, make sure the power supplies and fan
trays on the switch have the same airflow direction.
• As a best practice, install two power supplies on the switch for 1+1 redundancy.
• The switch supports mixed installation of power supplies consistent in the output power and
airflow direction. These power supplies are PSR450-12A1, PSR450-12AHD, and PSR450-12D.
The switch comes with power supply slot PWR1 empty and power supply slot PWR2 installed with a
filler panel. As a best practice, install two power supplies of the same model for the switch.
Select power supplies for the switch as required. For the power supplies available for the switch and
their specifications, see H3C S6825 Switch Series Hardware Information and Specifications.
