NSTALLING

THE

DPE M

ODULE

The Dual Processor Engine (DPE) module is the central processor for the

NETBuilder II

system. It includes a ﬂash memory drive for the system software

as well as a second ﬂash memory drive for back-up. Firmware parameters set

with the software SysconF command and with the ﬁrmware boot monitor are

stored on the ﬂash PROM (FPROM). A console port on the front of the module

provides local management. The DPE module, in combination with the 800

Mbps backplane, delivers consistently high throughput for all interface ports.

This chapter describes how to install the DPE module into the NETBuilder II

system.

If you have a NETBuilder II EZBuilt system with a preinstalled DPE module, go to

“Connecting a PC, Terminal, or Modem” on page 1-5.

The software ﬂash memory card does not ship with the stand-alone DPE

module and must be purchased separately from 3Com.

DPE Models

The DPE module is available in two models, the DPE 40 and the DPE

plus

The DPE 40 has a 50 MHz AMD 29040 RISC processor, 32 MB of instruction

and data memory (upgradeable to 64 MB), and 8 MB of shared (packet)

memory.

The DPE

plus

has a 62.5 MHz AMD 29040 RISC processor, 64 MB of instruction

and data memory, and 16 MB of shared (packet) memory.

The DPE 40 cannot be upgraded to a DPE plus.

Software and

Hardware Support

The DPE module needs NETBuilder software version 9.3.1 or later.

The DPE module is compatible with all NETBuilder II chassis.

Upgrading from a

CEC to a DPE

The DPE module has two built-in ﬂash memory drives and does not support

either the ﬂoppy disk drive or the internal ﬂash memory drive. The CEC module

uses the internal ﬂash memory drive to boot. Refer to

Upgrading NETBuilder

Family Software

for more information about upgrading your software.

When you replace the DPE module, the ﬁrmware parameters that were

previously conﬁgured by the SysconF command in the software are not

automatically updated to the FPROM of the replacement DPE module. You must

reconﬁgure these parameters. Refer to the software guide

for conﬁguration

information.

Before Installing the

Module

Before you install the DPE module into the NETBuilder II system, follow

these steps:

Observe appropriate electrostatic discharge (ESD) precautions.

ESD can damage circuit board components. Failures resulting from ESD may not

be covered under your warranty. To prevent ESD damage, follow these

procedures:

■

Keep the module in its antistatic shielded bag until you are ready to install it.

■

Do not touch pins, leads, or solder connections on the board.

■

Handle the board by the edges only.

■

Store or ship the module in static-protective packaging.

Observe proper grounding techniques when handling the module: Use a foot

strap and grounded mat, or wear a grounded static-discharge wrist strap.

Unpack and inspect the module for shipping damage.

If you ﬁnd any damage, ﬁle a report with the shipping company. If the module

must be returned to your network supplier, ship it in its original shipping carton.

If the original carton was damaged in shipment, repack the system in a carton

that provides equivalent protection.

Write down the serial number and MAC address from the labels on the

component side of the module.

You will need this information if you have to contact your network supplier.

Installing in the 4- or

8-Slot Chassis

To install the DPE module into the NETBuilder II 4- or 8-Slot chassis, follow these

steps. If you own the Extended chassis, refer to the next section.

Although it is not required, 3Com recommends that you turn off the system

before you install or remove a DPE module. If you do not turn off the system,

the bridge/router will automatically reset when you install the DPE module.

You will need a small, ﬂatblade screwdriver.

Insert the module into the top slot.

Although the ﬁgure shows an 8-Slot chassis, the procedure for the 4-Slot

chassis is exactly the same.

Hand-tighten the captive screws, then gently tighten them with a small

(1/8 in. – 3/16 in.) screwdriver. Do

not

overtighten the screws.

A solid connection of the front panel to the chassis is required for proper

operation. Do

not use the screws to force the board into place.

You are now ready to install the I/O modules. Refer to the appropriate I/O

module installation guides. After installing your I/O modules, refer to

“Connecting a PC, Terminal, or Modem” on page 1-5.

1-4 CHAPTER 1: INSTALLING THE DPE MODULE

Installing in the

Extended Chassis To install the DPE module into the NETBuilder II Extended chassis, follow these

steps. If you own the 4- or 8-Slot chassis, refer to the previous section.

Although it is not required, 3Com recommends that you turn off the system

before you install or remove a DPE module. If you do not turn off the system,

the bridge/router will automatically reset when you install the DPE module.

You will need a small, ﬂatblade screwdriver.

1Insert the module into the left-most slot marked A.

2Hand tighten the captive screws, then gently tighten them with a small

(1/8 in. – 3/16 in.) screwdriver. Do not overtighten the screws.

A solid connection of the front panel to the chassis is required for proper

operation. Do not use the screws to force the board into place.

You are now ready to install the I/O modules. Refer to the appropriate I/O

module installation guides. After installing your I/O modules, refer to the next

section, “Connecting a PC, Terminal, or Modem.”

Grasp left and right sides of

LED panel.

Turn the board so the 3Com logo is

on the bottom.

Slide board along guide rails until it

engages ejector tab notches.

Push ejector tabs closed until the

module is flush with the chassis.
