DC Power Supplies

Two power supplies and two power cords ship with each system. If dual power supplies will be fed with dual power sources, grounding potentials between the power sources should be measured and verified to be at or near zero volts potential. See “Grounding Systems” for more details.

Each power supply comes in two parts:

Both modules reside in the lower bay of the chassis. They are accessed from both the front and rear of the chassis as illustrated in Figure 1-7 “HP Blade Server DC Power Inlet Module (rear view)” and Figure 1-8 “HP Blade Server DC Power Supply (front view)”.

Each power supply has two visible LEDs that display operating conditions:
