When installing AC power supply units
When AC power supply units are installed on a Switch, the redundancy method is
2+2 redundancy.
In this method, two basic power supply units and two additional power supply units
for redundancy are required.
For the installation locations of the power supply units, see the following table.
A power supply unit can be installed in the PS1 to PS4 slots. The PS5
and PS6 slots cannot be used.
A power supply unit can be installed in the PS1 and PS2 slots. The
PS3 slot is not used.
Power supply units come in an AC model and a DC model. Do not
install both an AC power supply unit and DC power supply unit on a
single Switch.
If you install both units, they will not operate properly.
