Rev 3.4
Do not hot swap the power supply if your switch has only one power supply.
You must power down the system to replace the power supply unit when there
is only one PSU in the switch.
Risk of electric shock and energy
hazard. The two PSUs are inde-
pendent.
Disconnect all power supplies to
ensure a powered down state
inside of the switch platform.
3.6.5

Extracting and Inserting the Power Supply Unit

With both power supplies installed in the redundant configuration, either PSU may be extracted
without bringing down the system.
Make sure that the PSU that you are NOT replacing is showing all green, for
both the PSU and status indicators.
Power supply units have directional air flows similar to the fan module. The
Fan module airflow must coincide with the airflow of all of the PSUs. If the
PSU airflow direction is different from the fan module airflow direction the
system will shut down.
