Considerations

Restrictions with ATM and 10BASE-FL Modules

There are three primary upgrade considerations:

Once you install software version 7.0.0 or higher in a system that uses a revision 8.0 motherboard, you can never install software versions previous to version 7.0.0 in the future. To see if you have a revision 8.0 motherboard in your system, enter system display at the top level of the Administration Console. The first line of the display shows the product name and, in parentheses, the revision number of the motherboard.

If you are upgrading from a release prior to version 7.0.0, be aware that the menu item ip forwarding was changed to ip routing at version 7.0.0. If you have created automated scripts that include ip forwarding, edit them to reflect this command change.

If you are upgrading from a release prior to version 8.1.1,

be aware that the parameter broadcast address in the IP interface definition procedure was changed to advertisement address(es) at version 8.1.1. If you have created automated scripts that include broadcast address, edit them to reflect this command change.

Each CoreBuilder 2500 chassis features two slots for low-speed modules (Ethernet) and two slots for high-speed modules (ATM, FDDI, or Fast Ethernet). At this release, however, the system supports only one ATM module per chassis.

In addition, restrictions apply to certain configurations that mix one ATM module with two older Ethernet 10BASE-FL modules (3C201400; no longer orderable). The combination of these three modules causes certain systems to draw excessive power and eventually fail. Whether your system could be affected by this module-combination problem depends on the revision level of the system motherboard.

You can order a newer version of the 10BASE-FL module (3C201400A). The configuration restrictions described in this section do not apply to this newer version of the 10BASE-FL module.

To determine the revision level of your system motherboard, enter system display at the top level of the Administration Console. The first line of the display shows the product name and, in parentheses, the revision number of the motherboard.
