Updating Sensor software image

Before you begin the Sensor software upgrade, make sure:

  1. You have upgraded the Manager to the corresponding 9.2 version.

    See Upgrading the Manager.

  2. Your Sensors meet the requirements mentioned in Sensor upgrade requirements.
  3. You have understood the discussion in Reviewing the Upgrade Considerations.

New Sensor software images are released periodically by McAfee and are available on McAfee® Network Security Platform Download Server to registered support customers.

You can update a Sensor image using any of the four methods illustrated below. These methods include updating the signature sets as well.

Three of the methods involve updating your image using the Manager server:

  1. You can use the Manager interface to download the Sensor image from the Network Security Platform Update Server to the Manager server, and then upload the Sensor image to the Sensor.
  2. If your Manager server is not connected to the Internet, you can download the Sensor image from the Network Security Platform Download Server to any host, then import the Sensor image to the Manager server. You can then download the Sensor image to the Sensor.
  3. A variation of option 2: you can download the Sensor image from McAfee Network Security Platform Download Server to any host, put it on a disk, take the disk to the Manager server, and then import the image and download it to the Sensor.
  4. However, you may prefer not to update Sensor software through the Manager, or you may encounter a situation wherein you cannot do so. An alternative method is to download the software image from the Download Server onto a TFTP server, and then download the image directly to the Sensor using Sensor CLI commands. This process is described in this chapter as well.
