3.1.2 Unit Computer and Memory

A PowerPC PPC405GPr-400MHz 32 bit RISC processor with 16KB D-cache, 256MB SDRAM and 128MB Flash
memory manages the Ethernet switch via 32bit / 66MHZ PCI local bus. The CPU is accessible via serial port or
10/100BASE-T Ethernet from the RTM or in-band via the GbE switch.

Besides the direct PCI connection to the management interface of the switch, a PCI Ethernet controller links
the Unit Computer to a switch port which is configured as 10/100BaseTX.

3.1.2.1

Fast Ethernet Management Interface

The 10/100BaseTX Ethernet management interface connects the Unit Computer to the RTM. It uses the follow-
ing pins of the ATCA Zone 3 connector:

3.1.2.2

RS232 Management Interface

One RS232 interface of the Unit Computer is the serial port which is routed to a miniature connector on the
front plate. An adapter cable is available from Kontron to establish a connection with a terminal with a stan-
dard DB9 serial port. Additionally, the Unit Computer’s serial port is routed to the Zone 3 connector so that a
connection can also be established by using an appropriate RTM like the RTM8030. If both ports are connected
to a terminal, the front plate connection takes precedence over the RTM connection.
