2.7 DNR-CPU/NIC
Module
The DNR-CPU/NIC Core Module (DNR-CPU-1000, DNR-CPU-1000-02, or
DNR-CPU-1000-03) occupies two slots of a DNR-X-1G RACKtangle
enclosure.
The DNR-CPU/NIC Core module consists of a Freescale (formerly Motorola)
MPC8347 or MPC8347E 32-bit 400 MHz CPU and peripheral devices (USB 2.0,
RS-232, NIC, SD, etc) for use with a Gigabit Ethernet communication network
and an internal 66 MHz 32-bit common logic interface bus. The NICs are copper
(1000BaseT) interfaces. The module has an RS-232 port used for configuration
and also two USB 2.0 ports (controller and slave) for general purpose use (not
implemented yet). LEDs on the front panel of each module indicate the current
operating status of the device.
