3Com ENTERPRISE OS 11.3 manual Upgrading The Software Image Only

56CHAPTER 6: UPGRADING THE SOFTWARE IMAGE ONLY

7Click on the Advanced button if you want to customize the upgrade process, that is you do not want to perform all of the upgrade at this time.

The Advanced Dialog box appears.

8Click New Hardware if you are replacing your bridge/router with a new system. For example, click New Hardware if you are replacing the CEC module with a DPE module.

You cannot upgrade to a different platform. For example, you can only upgrade an OfficeConnect bridge/router to an OfficeConnect bridge/router. You cannot upgrade a SuperStack II NETBuilder bridge/router to a SuperStack II NETBuilder SI bridge/router. The only exception is an upgrade from a NETBuilder II CEC module to a DPE module.

9If you want to alter the Reboot Timeout, enter a new number in the box. The default setting is appropriate for most networks.

10Click the check box for each of the stages you want to complete in the current operation.

11Click OK.

12Click Apply to begin the upgrade. The Status page appears.

13If you are performing a hardware upgrade, replacing a CEC module with a DPE module for example, a message to replace the hardware appears after the software has been backed up to the NMS. Replace the hardware at this time.

14When the upgrade is complete, the bridge/router reboots from the new software. If the boot is not successful:

■For automatic recovery, the bridge/router reboots from the old software.

■For manual recovery, you must configure the bridge/router at the local console to reestablish IP connectivity. Once connectivity is established, you can restore the software to return the bridge/router to a preupgrade state. See Chapter 7 for the procedure to restore connectivity and the software.

15Click Home then Exit to exit Upgrade Link.
