The weight of a DC power supply unit is 5.6 kg and the front-to-back
measurement is 163 mm. When removing a DC power supply unit
from a Switch, support the DC power supply unit itself.
If you pull the unit carelessly, it might fall, possibly resulting in injury.
CAUTION
When removing a power supply unit, install a blank panel. If you
continue using the Switch without attaching a blank panel, the airflow
in the Switch cannot be maintained. As a result, the temperature
inside the Switch will rise, possibly resulting in a failure.
In addition, the radio waves generated by the Switch might affect
another device, or the radio waves generated by another device might
affect the Switch, resulting in a malfunction.
NOTE
Make sure you reattach the screws and cover you removed from the
power supply unit to the power supply unit after you have replaced it.
