Preparing a USB flash drive for installation

The M2250, M2600, and M2700 appliances do not have a DVD drive. Therefore, use of a DVD with these appliances is not supported. Installing the Core ISO on these appliances is done from a USB flash drive.

USB flash drives are only supported on M2250, M2600, and M2700 appliances.

Before you begin 

Ensure that the USB flash drive meets the following minimum requirements:

  • USB Standard 2 or 3
  • USB Connector Type-A

Procedure 

The USB flash drive preparation steps vary somewhat between Core 11.3.1.0 and older releases from Core 11.4.0.0 and newer releases. Follow the steps for your release:
