PCI Gigabit Ethernet Controller (Integrated NIC)
The six-channel variant of the CP932 provides one onboard NIC Gigabit Ethernet channel used
with the Intel 82541PI PCI Gigabit Ethernet controller. This chip provides, on the one hand, a
PCI interface communicating with the host over the CompactPCI backplane and, on the other
hand, a ready-to-use Gigabit Ethernet channel on copper PHY level.
The NIC Gigabit Ethernet channel is connected to the onboard PHY2 transceiver over two
magnetic devices. PHY2 itself is connected to the Broadcom BCM5388 Gigabit Ethernet switch
over the RGMII interface.
The network status of the PCI Gigabit Controller can be monitored via three onboard LEDs.

Onboard LEDs
The six-channel CP932 is equipped with three onboard LEDs for monitoring the network status
of the PCI Gigabit Controller.
