Frame PSU Power Output Considerations
• The HPF-9000 uses power supply units (PSUs) that provide a 400 W
capacity per each supply. Note that with redundant supplies, the power
delivery may not be exactly split between the two supplies. The maximum
available frame power (net) for frame slots is 360 W total net (18 W per slot
when utilizing 20 slots, or 36 W per slot when utilizing 10 slots as used for
high power or double-power cards).
Note:
Refer to Frame Card Capacity and Rear I/O Modules (p. 1-5) in Chapter 1,
Introduction for descriptions of Cobalt rear I/O module types and conventions.
• PSU1 is installed on the left side of the frame (viewed from front); PSU2 is
installed on the right side of the frame (viewed from front). Both supplies are
identical and interchangeable. They are flipped vertically when installed in
respective slots to maintain exhaust out of the rear sides of the chassis.
• DashBoard™ presently reports current output from each PSU in milliamps.
The value reported is not directly compatible with the PSU and requires
scaling as follows:
• Similarly, DashBoard™ presently under-reports power. The displayed value
can be corrected as follows:
Ventilation Considerations
• HPF-9000 Power Supply Unit (PSU) cooling is independent and separate
from the card cage chassis to help mutually isolate card cage and PSU heat
dissipation. PSU exhaust is out the rear sides; obstructions should be
minimized in this area.
• Rear I/O Modules (other than “HV High-Ventilation” types identified as
“-HV”) offer limited secondary exhaust ventilation features, with the
primary exhaust ventilation feature being the ventilation holes on the top of
the frame. Overall exhaust ventilation may be inadequate if the ventilation
holes on the top of the chassis are obscured.

= Actual Current (in Amps)
(Example: 5000/262.5 = 19.05 A)
DashBoard displayed value x 3.81 = Actual Power (In Watts)
(Example: 80W x 3.81 = 305 W)
