DPU Chassis Input/Output

Connections

Overview

All input/output connections are contained on the front DPU chassis panel.

The chassis contains:

• Two serial ports

• Two 10Base-T Ethernet ports

• One backup link port

This chapter describes each link in some detail.

Ethernet Network Connections

The DPU chassis contains two 10Base-T Ethernet ports using RJ-45

connectors to interface with the maxNET communication network. Network

A and Network B operate at 10Mbps as independent networks. Because the

Ethernet channels are independent, a fault on one network or processor will

not affect the operation of the other, or cause a DPU failover. Ethernet

messages are sent/received based upon the DPU’s Ethernet address with

minimal Control Processor intervention.

Configuring the Ethernet Switch

Each DPU connects to the maxNET through two external Ethernet switches –

one for Network A and one for Network B. The Ethernet switch ports that

connect to DPUs should be configured for 10Mbps full-duplex operation.

Switch ports that connect to other switches should be configured for

100Mbps full-duplex operation. Refer to the user manuals that came with

your Ethernet switch to learn how to change the port settings.
