4.1 Click Software Upgrade to bring up the Upgrade Product and OS on Appliance window.
4.2 Click Add Upgrade Entry to bring up the Add Appliance Upgrade Information window.
4.3 Select the chassis IP address from the pull-down menu.
4.4 Click Browse for the Product Upgrade File. The default directory is C:\Program Files\Spirent Communications\Spirent TestCenter X.XX\Layer 4-7 Application\TGZ. Note: it is important to select the correct firmware directory that matches chassis platform being updated e.g. 290, 2900,3100, 3100B, C100. Version 3.80 is being use for the upgrade/downgrade example. If you upgrade/downgrade a different version, then select the version's firmware. Note the OS Upgrade File is not required.
4.5 Click Add.
5. Click Upgrade.
The 3100B and C100 Appliances will finish its firmware upgrade before the AONIC 10G interface. The GUI may say the upgrade is complete after approximately 5 minutes, but the process will take 30 minutes to complete. Please do not reboot the 3100B or C100; doing so will damage to the AONIC 10G NICs. Please allow at least 30 minutes until you proceed with any testing.
