Key Considerations

Before installing 3Com Network Director, you must ensure that 3Com Network Supervisor Advanced Package v2.0 is unlocked:

1Launch 3Com Network Supervisor v4.0

2If the Registration Information dialog box is not displayed at startup, select the Help > Register Now menu option to display that dialog box.

3Select Advanced Package v2.0 in the list of installed packages.

4If Advanced Package v2.0 is not already unlocked (i.e. Registered), you must unlock it by:

a Entering the license key for Advanced Package v2.0 - the license key is printed inside the CD sleeve.

b Entering the activation key for Advanced Package v2.0 in the dialog box - a copy of the activation key was sent to you by e-mail when you registered Advanced Package v2.0.

c Clicking OK in the Registration Information dialog box - you should get confirmation that the Advanced Package v2.0 functionality is now unlocked.

If the activation key is rejected, this probably means that the workstation on which you installed 3Com Network Supervisor Advanced Package v2.0 is not the same as the one for which you originally obtained an activation key; if that is the case, please refer to “I want to install my upgrade from 3Com Network Supervisor Advanced Package v2.0 to 3Com Network Director on a different workstation.” on page 55.

You may now install 3Com Network Director:

1Uninstall 3Com Network Supervisor v4.0 - this will also uninstall Advanced Package v2.0.

2Install 3Com Network Director v1.0.

This will start the evaluation period, which expires in 60 days. To continue using 3Com Network Director beyond the 60-day evaluation period, you must activate the product:

1If you have not already done so, order 3Com Network Director from your reseller, product number 3C15500U. For more information on product numbers, see “What product number is right for me?” on page 54.

2Run 3Com Network Director and click on Activate Now... in the About dialog box - The Activation Wizard will launch.
