2.3.2 Power Requirements
The following table contains the Power requirements:
2.4 Installing the Accessories
The following sections contains procedures on how to install the accessories on the iVPX7225
board.
Table 2-2 Power Requirements
Voltage Rail Minimum Power Typical Power Maximum Power
5V VPX PWR (VS3) 22W 32W 40W
3.3V Total 4W 5W 6W
Minimum Power: Representative of running Linux in a pure text mode (No X11/No GNOME), resting
idle the Linux login prompt.
Typical Power: Representative of running a mixture of CPU and I/O loads, including exercising
memory, local and backplane PCIe traffic, SATA, Gigabit Ethernet, FRAM and USB.
Maximum Power: Calculated worst-case power, based on device TDP and is not expected to be
reached under normal operation. A CPU-intensive workload could encroach upon this value.
All power requirements are specified with “no” XMC populated in the XMC site. The XMC site draws
power directly from the VPX backplane. No onboard regulation.
In the absence of an XMC, the iVPX7225 draws no power from the VPX 3.3V VS2 rail. However, the
“3.3V Total” power specified above includes a VS2 contribution due to the presence of an RTM in the
test configuration. The RTM draws 3.3V predominantly from VS2. One can therefore estimate the
iVPX7225 “3.3V AUX” power consumption by subtracting the iVPX7225 RTM 3.3V power
consumption from the total. The iVPX7225 “3.3V AUX” power consumption is fairly static at 2-3W.
Refer iVPX7225 RTM IU Manual for the RTM power consumption specifications.
Proper alignment of the XMC connector is essential to prevent damage to the XMC module
and/or to the mating XMC connector on the iVPX7225.
