AXP1440-C07 Shelf Description
AXP1440-C07 Shelf Description
2.4 Power Consumption
The following table shows the total power requirements for the shelf. Power consumption
breakdown is also shown in the table.
2.5 Shelf Ground Configuration
The AXP1440-C07 shelf was tested in the default configuration of logic ground and shelf
ground connected and does not connect -48VDC Return with shelf ground. The AXP1440-
C07 platform has been tested in the default configuration and complies with safety and
regulatory standards.
As a compliant AdvancedTCA shelf, the AXP1440-C07 allows system integrators, at their
own discretion, to remove the mechanism which connects logic ground to shelf ground and
install the mechanism that connects -48VDC Return to shelf ground.
Table 2-1 DC Shelf Power
FRU
Nominal Power (Watts)
Shelf Only Maximum Power (Watts)
Shelf with Payload
PEM Subsystem 5W 15W
Fan Subsystem 100W 1000W
Shelf Management 6W 20W
ATCA Blades - 4027.5W
Total Shelf Power 111W 5062.5W
NOTICE
Total maximum shelf power allocation is 5062.5W, defined in shelf FRU power
distribution record. The ATCA blade power distribution record in shelf FRU is 350W.
NOTICE
If the system integrator exercises the option of removing the connections from logic
ground to shelf ground and or adds the connection between -48VDC Return and
shelf ground, the responsibility for maintaining compliance to CSA (C/US)/VDE
safety requirements and EMI/RFI emission limits rests entirely with the system
integrator and installer.
