3.0 Software Version Information

If you plan to install the CoreBuilder 5000 A/DMM in the
same hub with a CoreBuilder 5000 Fault-Tolerant
Controller Module (Model Number 3C96000M-RCTL),
ensure that the Fault-Tolerant Controller Module is
running software Operational Version v1.15 or later and
Boot Version v1.04.

3Com recommends that all DMMs that are installed in the
same hub with the A/DMM run software Version v6.0 or
later.

Before you install the A/DMM into a hub that
contains an RCTL and DMM or DMM-EC, make sure
that the RCTL is running Version v1.15 code or later
and that the installed DMM or DMM-EC modules
are running Version v6.00 or later.

To manage the A/DMM through SNMP, use 3Com
Transcend
v5.00, or 3Com CoreBuilder 5000 Manager for Windows.

5.0 Installation Precautions

Electrostatic discharge (ESD) can damage static-sensitive
devices on circuit boards. Follow these precautions:

■ Do not remove the module from its antistatic bag until

you are ready to inspect or install it.

■ Handle the module by the front panel only.

■ Use proper grounding techniques when you install the

module. These techniques include using a foot strap
and grounded mat, wearing a grounded static
discharge wrist strap, or touching the grounded rack or
other grounded source just before you handle the
module.

slide the module into place.

■ Do not push the module all the way into the hub until

the module ejectors (if any) are open.

6.0 Unpacking Procedure

Follow this procedure to unpack your module:

1

Verify that the module is the model that you ordered by
examining the model number on the side of the
shipping carton.

2

Remove the module, in its antistatic bag, from the
shipping carton.

3

Following the instructions in Section 5.0, "Installation

8.0 Installing the A/DMM

You do not need to power off the CoreBuilder 5000
Integrated System Hub to install
You can insert the module while the hub is operating (this
is called a

hot swap

).

To install the module:

1

Before you start the installation process, read Section 5,
"Installation Precautions".

2

To expose a slot for the module, remove a blank
faceplate on the hub controller bay (which is below the
main module bay). You can install the module in either
slot.
Make certain that the Expansion Memory Card is
properly seated on the Expansion Memory Card holder.

3

Insert the module into the module guides at the top
and bottom of the controller bay slot and slide it into
the hub by pressing firmly at the top and bottom of the

Lock the module into place by applying pressure to the
module front panel with both hands while you push the
ejector handle inward toward the front panel with your
thumb. Ensure that the module remains fully seated in
the backplane connector while you close the ejector
handle. Lift the end of the ejector handle until it locks

To secure the module front panel to the front of the
hub, use a flat-blade screwdriver to tighten the top and
bottom screws to torque specification 3 to 5
inch-pounds.

WARNING:

For safety reasons and to ensure
adequate cooling airflow, install blank faceplates
over all empty slots.

3Com recommends that, after you install the A/DMM, you
make it the
