This chapter describes installation and setup procedures for the 3Com CoreBuilder® 9000 Enterprise Management Engine (EME). The sections are:
Before you install modules in a CoreBuilder 9000 chassis, make sure that you have completed these tasks:
1 . Complete the chassis unpacking and installation procedure, as described in the Chassis Quick Installation Guide for the CoreBuilder 9000 Enterprise Switch 8-Slot Chassis and 16-slot Chassis, or the 7-slot Chassis Quick Installation Guide for the CoreBuilder 9000 Enterprise Switch. You can install the chassis in a rack, on a shelf, or on a table.
2 . Read the CoreBuilder 9000 Enterprise Switch Getting Started Guide to make sure that you have all the required components to get your system up and running and that you have completed any prerequisite work.
3 .
Complete the EME unpacking and installation procedure, as described in the Enterprise Management Engine Quick Start Guide for the
CoreBuilder 9000 Enterprise Switch.
4 . Plug power cords from all installed power supplies into electrical outlets.
3Com recommends that you install one EME prior to adding switch fabric modules, interface modules, and switching modules.
One EME is required in each chassis. Install an EME (Model Number 3CB9EME) in one of the two management module slots:
If you are installing two EME modules for redundancy purposes, you must install the EME modules in the following order:
The lower-numbered EME slot in the chassis is designated as the slot for the primary EME. The other slot is designated as the slot for the secondary EME.
See the Enterprise Management Engine Quick Start Guide for the CoreBuilder 9000 Enterprise Switch for details about installing EME modules.
If you are installing one EME module and one EMC module, you must install the modules in the following order:
See the Enterprise Management Engine Quick Start Guide for the CoreBuilder 9000 Enterprise Switch for details about installing the EME module. See the Enterprise Management Controller Quick Start Guide for the CoreBuilder 9000 Enterprise Switch for details about installing the EMC module.
To install a CoreBuilder 9000 switch fabric module, interface module, or switching module, see the module-specific installation instructions in the Quick Start Guide that accompanies the module.
You do not need to turn off power supplies to install modules in the CoreBuilder 9000 chassis. You can install CoreBuilder 9000 modules while the chassis is operating. This is called a hot insert. You can also remove a module and install a replacement in that slot while the chassis is operating. This is called a hot swap.
Before you remove the primary (active) EME, ensure that a secondary (standby) EME resides in the chassis.
Before you remove the primary (active) switch fabric module, ensure that a secondary (standby) switch fabric module resides in the 8-slot chassis or 16-slot chassis.
When you remove the primary modules, the secondary modules activate and provide uninterrupted service to other modules in the chassis.
CAUTION: Do not install or remove modules during system power-on or while software is downloading to modules in the chassis.
After you install an EME in the chassis, and before you configure the chassis and install other modules, verify that the EME is running correctly. This section explains how to verify EME operation before you enter commands.
To verify that your EME is operating correctly, watch the four-character LED display located on the EME front panel during system power-on. Table 3 shows the sequence of characters that appear in the LED display during a successful system power-on.
The system displays the following message on the management console when the EME is installed properly and you have made the RS-232 connection:

To ensure that a broken module LED is not providing a false indication of current conditions, enter the show chassis command to verify that chassis operating conditions are normal.
EMC module LEDs operate differently than EME LEDs during a software download. For a description of LED status during an EMC module download, see the Enterprise Management Controller Quick Start Guide for the CoreBuilder 9000 Enterprise Switch.
When two EMEs are installed in a chassis thus creating Redundancy, and the Primary EME fails over, the Standby LED on that EME continues to display Active. This is because only the SMC component fails over while the SCC component remains active.
The EME front panel includes a display button that is located next to the LED display, and labeled DSPLY. The LED display shows status information when you power on the EME, and shows Pri when the EME is running normally.
When the EME is running normally, the following information appears in the LED display when you press the display button:
This section describes the connections that you can make to communicate with the EME. Choose the connection that is most appropriate to your installation. After you have connected the EME, you can configure EME characteristics. This section includes:
Connect the EME to a 10 Mbps (Megabits-per-second) Ethernet network or device using the front panel 10BASE-T Media Dependent Interface (MDI) port. The EME uses an RJ-45 connector for the 10BASE-T port.
Table 4 lists the 10BASE-T MDI port pinouts.

The EME 10BASE-T port is configured as an MDI or host port. To connect the EME to an MDI crossover (MDI-X) or switch port, use a standard RJ-45 jumper cable. To connect the EME directly to a host or another MDI port, use a crossover cable.
Table 5 lists the MDI-to-MDI crossover cable pinouts.

Connect the EME to a terminal or modem using the front panel RS-232 Console Port or RS-232 Auxiliary Port connectors. The EME uses 9-pin connectors for the RS-232 ports.
Table 6 and Table 7 list the console port and auxiliary port pinouts.
Table 8 lists 9-pin-to-9-pin assignments for connecting your PC to the front panel of the EME.
Table 9 lists 9-pin-to-25-pin assignments for connecting your PC to the front panel of the EME.
The EME Console Port permits dial-in modem use. To use a dial-in modem:
1 . Ensure that the modem supports the AT command set.
2 . Select one of the following baud rates: 300, 1200, 2400, 4800, 9600, 19200, or 38400.
Default baud rate
3 . Place the modem in Dumb/Auto Answer mode. To do this, enter the commands that are listed in Table 10 from a terminal that is directly connected to the modem. Press Enter after each command.

To verify that the CoreBuilder 9000 chassis and all modules have been installed correctly:
1 . Confirm that communication can be established on all network segments that you have enabled.
2 . Confirm that the Network Activity LED on each installed module correctly indicates network traffic status. Table 11 lists the Network Activity LED status indicators.
Not all modules have Network Activity LEDs.
If an installed module's Network Activity LEDs do not appear as shown in Table 11 when the chassis is powered on, see Chapter 8, "Troubleshooting the EME" for more information.
The EME file system is an area on the EME that stores:
The file system also acts as a temporary storage area for software images that are downloading through the EME to other modules in the chassis.
Under most conditions, you do not need to access or manage the file system. The file system supports commands that allow you to view the files in the file system or to delete certain files.
The following commands are available to display and manage the EME file systems, which store software configuration files:
The show file command displays files in the file system storage.

Number of files: 13
Number of bytes in file system: 11945984
Number of bytes used: 1157120
Number of bytes available: 10788864
Number of bytes cleaned: 10788864
The clear file <filename> and clear file all commands delete the files that you specify from the file system. If you enter all to delete all files, the system prompts you to confirm that you want to delete each file before you delete it. If you enter n (no), the system does not delete the file.
Example:
CB9000> clear file all
Are you sure you want to delete file EventLog?(y/n): n
Are you sure you want to delete file a.1 (y/n): y
File a.1 deleted.
Are you sure you want to delete file a.11? (y/n): y
File a.11 deleted.
The system continues to prompt you about files until all files are either deleted or saved.
The clear file_system command deletes all files that are stored in the file system, reinitializes the file system, and resets the EME. This command clears the file system even if files are currently open or being updated.
Use this command only if the combined number of bytes that individual files use is inconsistent with the figure in the Number of bytes used: field in the show file display. The number of bytes that each file uses appears in the FileSize column of this display.
CAUTION: This command deletes all files from the file system and reinitializes the file system storage area. Do not use this command unless the file system has been corrupted in some way.
Before you clear the file system, you can store a copy of the event log on the file server with the upload eme event_log <ip address> <filename> command, if you want to save the content of this file.
Example:
CB9000> clear file_system
!!WARNING!!
This command will clear all files and reset the EME.
Consult the user guide for information on operational
considerations before continuing with this command.
Do you wish to continue with clear file_system command?(y/n):y
Preparing to clear file_system.
Ready to clear file_system.
Do you wish to continue with clear file_system command?(y/n):y
Clearing file system please wait for EME to reset.
After the EME reset is complete, you can log in to the EME.
The EME Event Log captures various events. You can specify characteristics of the Event Log, and view the status and contents of the Event Log through EME commands.
To display the status of Event Log characteristics, use the show event log status command.
Example:
The event log full default is WRAP.
To display the contents of the Event Log, use the show event log verbose, show event log nonverbose or show event log <number> commands.
Example:
CB9000> show event log unfiltered nonverbose
