Update Firepower Devices - Manually

Share on:

This is short and hopefully helpful post on how to manually update Cisco Firepower Devices. I have run into this problem a couple of times which is pushing this update with the FMC sometimes just fails and it never really seems to download the update to the Firepower sensor. On the FMC it will stay on "Initializing" for an hour and timeout so here are the steps to manually update your Firepower Sensor:

  • You can manually update this by either connecting to the console or ssh into the sensor.
  • Once in you'll need to the bash shell so type the command "expert" to get into it.
  • Next, you need to evaluate to the root account by using sudo su
  • SCP copy the update to the /var/sf/updates folder, you can either copy from the FMC or something else that has the update you are looking for.
1scp admin@192.168.1.5:/image.sh /var/sf/updates

If the update is on the FMC the path is /var/sf/updates and it would look something like this, we are pulling from the FMC and copying to the sensor to /var/sf/updates folder.

1scp admin@192.168.1.5:/var/sf/updates/Cisco/FTD/Patch-6.2.0.2-51.sh /var/sf/updates

Install the update via install_update.pl /var/sf/updates/image.sh and watch the console when the upgrade completes your sensor will reboot and no action is needed on the FMC it will automatically detect the new version.

Below is an omitted copy of the console output when upgrading Cisco Firepower devices, keep in mind this session has to stay active don't close or disconnect while updating, let's just say hitting CTRL+C during this process is an instant killjoy, and although it can be fixed I wouldn't advise it!

 4We trust you have received the usual lecture from the local System

 8    #2) Think before you type.
 9    #3) With great power comes great responsibility.
