Before installing the license file, save a backup copy in a safe place.
Two methods of installing the license are described below.
If you are not using a PC connected to the EXT, you must use a USB storage device to install the license, see Using a USB Storage Device.
If you are using a PC connected to the EXT to install the license remotely, see Using Keysight License Manager on a PC Connected to the EXT.
You can manually install the license in the EXT using a USB storage device.
Copy the license file to a USB storage device. The license file is attached to the email message you received when you redeemed your license.
Insert the storage device into the USB port on the front panel of the EXT.
Wait a few seconds for the license to be copied to the hard drive. A popup message from Keysight License Manager (KLM) appears on the EXT front panel that shows the license model number and version with the following message: "Successful License Installation."
Remove the USB storage device.
If a USB storage device is not available, you can install the license using the Keysight License Manager (KLM) on a PC that is connected to the EXT through a LAN connection. This method requires that the EXT and PC have the same version of KLM installed.
Verify that the same version of KLM resides on both the EXT and the PC.
