you may decide not to install the MIB collection to save time during the

install, since the MIBs can take up to an hour to install.

Activation Once you have installed 3Com Network Administrator, you will have a

60-day grace period within which to activate your software. When you

launch 3Com Network Administrator for the first time the About dialog

will be displayed as shown in Figure 3

website to retrieve your activation key.

3 Once you have your activation key, enter it into the Activation Key text

box and click Finish to complete the activation process.
