BCM957416A4160C Data Sheet Dual-Port 10GBASE-T Ethernet PCI Express 3.0 x8 Network Interface Card
1.9 Power Supplies
All power is derived from the PCI Express Host Interface Connector 12V supply pins. These voltage supply pins feed on-
board regulators that provide the necessary power to the various components on the card. The NIC has nine switching
regulators, which power the card's various +1.0V, +1.25V, +1.8V, 1.9V, 2.5V, and +3.3V loads. The 3.3V power (+3.3V) and
3.3V auxiliary power (3.3V
aux
) from the PCIe edge connector are also used to supply the power control logic and signals.
1.10 LED Functions and Locations
The 10GBASE-T port supports two LEDs to indicate traffic activities and link speed. The LEDs are visible through the cutout
on the bracket as shown in Figure 3. The LED functionality is described in Table 1.
