Input Power Information - Oracle Netra X5-2 Installation Manual

Caution -
building or unexposed wiring or cabling only. The intra-building port(s) of the equipment or
subassembly must not be metallically connected to interfaces that connect to the outside plant
wiring. These interfaces are designed for use as intra-building interfaces only (Type 2 or Type 4
ports as described in GR-1089-CORE, Issue 6) and require isolation from the exposed outside
plant cabling. The addition of primary protectors is not sufficient protection in order to connect
these interfaces metallically to outside plant wiring.
Caution -
building cabling or wiring that is grounded at both ends, except the ethernet ports.

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 -
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.
