Enterprise Management
Engine Quick Start Guide
For the CoreBuilder®9000 Enterprise Switch
Module Description The 3Com CoreBuilder®9000 Enterprise Management Engine (EME) is an
SNMP-based network management module that enables you to
configure and manage the 3Com CoreBuilder 9000 7-slot chassis, 8-slot
chassis, and 16-slot chassis, and their modules. Use the EME (Model
Number 3CB9EME) to:
■Manage the chassis through the EME command interface, which you
access through the serial port or through SNMP (Simple Network
Management Protocol).
■Gain access to the Administration Console of switching modules,
switch fabric modules, and interface modules.
■Gain access to the Asynchronous Transfer Mode (ATM) Local
Management Application (LMA) to manage cell-based ATM interface
modules and ATM switch fabric modules. See the ATM Enterprise
Switch documents on the CoreBuilder 9000 Documentation CD-ROM
for more information.
An EME combines the functions of a management module and a
controller module. You can install a second EME in the chassis as a
redundant EME. The redundant, or secondary, EME provides standby
management support if the first, or primary, EME fails or becomes
unavailable for any reason. Or, for standby controller support, you can
install an Enterprise Management Controller (EMC) module instead of a
second EME.
This document provides the basic information that you need to install and
use the EME.

Status LEDs
Table 1 lists the status LEDs and explains their modes. If one EME is
installed in the chassis, you can install an EMC in the adjacent slot. If two
EMEs are installed, you cannot install an EMC.
Character Display LEDs
The four-character display LEDs display alphanumeric information about:
■The current operating state of the module.
■The release number of the EME embedded software.
■Any environmental fault. For example, when a power supply, fan, or
overheat fault occurs, the fault automatically appears in the character
display.
When you press the DSPLY button, the character display LEDs default to
the module’s operating state.

Reset Buttons
The following three reset buttons reside on the front panel of the EME
module. To press any of these buttons, use a pen tip or other nonmetallic
tool.
■DSPLY button — Press this button to reset the four-character display
LEDs on the EME front panel to zeroes (0000). The LEDs display
alphanumeric characters that indicate which EME is the primary and
which is the secondary.
■EME Reset button — Press this button to reset the EME. Resetting
the EME prevents traffic from reaching the other modules in the
chassis. Press the EME Reset button only if you suspect a problem with
the EME that you cannot fix through management commands.
■Reset Chassis button — Press this button to reset all the modules
that are installed in the chassis.
CAUTION: Although resetting the chassis causes a temporary
interruption of the data paths to all of the modules, in some instances
this interruption can become permanent and result in the loss of traffic.
Press the Reset Chassis button only if you suspect a problem with the
chassis that you cannot fix through management commands.
Ports
The following three ports reside on the EME module front panel:
■RS-232 Port — Shielded male DB9 connector for connecting an
RS-232, two-channel cable for serial communication
■10B-T Port — RJ-45 10BASE-T connector for an RJ-45 10BASE-T
Ethernet connection
■AUX Port — Shielded male DB9 connector for connecting a second
RS-232, two-channel cable for serial communication

Enterprise Management Engine Quick Start Guide 9
Installing the EME Install at least one EME (Model Number 3CB9EME) in each
CoreBuilder 9000 chassis. Each chassis has two slots that are dedicated
for EME installation (slot 8 and slot 9 in the 7-slot chassis, slot 9 and slot
10 in the 8-slot chassis, and slot 17 and slot 18 in the 16-slot chassis).
You can install the first EME in either slot. You can only install one of the
following modules in the second slot:
■A second EME for standby management support
■An EMC for standby controller support
You do not need to power off the CoreBuilder 9000 chassis to install,
remove, or replace the EME module. You can insert the module while the
chassis is operating. (This is called a hot swap.)
To install an EME module:
1Before you start the installation process, read “Safety Precautions” and
“Handling Precautions” earlier in this guide.
2To expose a slot for the module, remove a blank faceplate from slot 8 or
slot 9 in the 7-slot chassis, from slot 9 or slot 10 in the 8-slot chassis, or
from slot 17 or slot 18 in the 16-slot chassis.
WARNING: Hazardous energy levels exist inside the chassis. Do not place
hands or objects into the chassis or touch any components on an installed
module.
3Open the module ejector handles (Figure 3).
4Insert the module into the module guides:
■For a 7-slot chassis, hold the module horizontally with the LEDs at the
left. The module guides are on the left and right of the slot.
■For the 8-slot chassis and 16-slot chassis, hold the module vertically
with the LEDs at the top. The module guides are at the top and
bottom of the slot.
CAUTION: Be careful not to twist or bend the EME module while you
insert it into the chassis.
5Slide the EME module into the chassis by pressing firmly on the front
panel. Figure 3 shows how to install the module into a 16-slot chassis.

6To engage the EME connectors and backplane connectors, apply pressure
to the module front panel with both hands while you push the ejector
handles inward toward the front panel with your thumbs. You feel a
slight resistance as the connectors engage.
CAUTION: If the resistance is too great, the EME connectors and
backplane connectors may not be aligned. Forcing the EME inward can
damage the module’s connectors or the backplane connectors. If
necessary, remove and reinsert the EME, ensuring that the connectors are
properly aligned. Do not tighten the spring-loaded screws to seat the
module.
Ensure that the module remains fully seated in the backplane connector
while you close the ejector handles. Push the end of each ejector handle
inward toward the front panel until the ejector handle is parallel with the
front panel.
