If you have a new module that uses software Release 3.0, you can now

 

select a slot for your module and install it. See the Quick Start Guide for

 

your module for guidelines and procedures.

modules.

 

CAUTION: All modules in a single chassis must operate at compatible

 

software levels. When you purchase a new chassis and modules, you

 

must verify the software release on all modules and upgrade as necessary

 

in the order specified in the following procedure.

To verify and update all modules to Release 3.0, follow these steps:

1Install one EME module in the powered-off chassis.

For the installation procedure, see the Enterprise Management Engine Quick Start Guide for the CoreBuilder 9000 Enterprise Switch.

2Power on the chassis, if you have not already done so as part of the EME installation procedure.

3At the EME prompt, enter:

show eme

The resulting display includes the software release number.

4Compare the software release number in the display with the compatibility requirements in Table 1 in Chapter 1.

5If necessary, upgrade the EME according to the procedures in the CoreBuilder 9000 Release Notes for Management Modules.

6With the chassis powered on, select slots for all modules and install them.

See the Quick Start Guide for each module for slot guidelines and an installation procedure.

7Verify the software releases on all modules. At the EME prompt, enter:

show module all verbose

8Compare the software release numbers in the display with the module compatibility requirements table in each CoreBuilder 9000 Release Notes to identify which modules you need to upgrade.

9Have ready the software upgrades and associated release notes for all modules that you are upgrading.
