Input Power Information
The total input power for the server is divided equally among the power supplies in
operation. Reversing the positive and negative inputs to the power supplies of a DC
input server will not cause damage. However, the power supplies with reversed
input will not operate.
The inputs to a power supply are isolated from the server chassis and the other
power supply inputs. The AC or DC power inputs might be at different voltages
within the acceptable range and might have different offset voltages relative to the
server chassis.
Note – The server does not require an additional surge protector for the AC power
configurations if the facility has a surge protector that limits voltage surges to less
than 2000V. You can, however, install a surge protector if your site requires an
additional protector.
Note –
Safety agency requirements prohibit Oracle Corporation from changing a
product from AC input to DC input or from DC input to AC input after the product
has been removed from the agency approved manufacturing site.
