Do not remove power to IDS-4215 during the update process, otherwise the upgrade can get corrupted. 
If this occurs, IDS-4215 will be unusable and require an RMA.

This section provides information on upgrading to IPS 6.0(1)E1, and contains the following topics:

The following upgrade notes and caveats apply to upgrading to 6.0(1)E1:

If you have 4.x installed on your sensor, you must upgrade to 5.0(1), then upgrade to 6.0(1)E1.

You can upgrade all 5.0 or 5.1 sensors directly to 6.0(1)E1.

5.1(3) and earlier sensors may display an error message that the upgrade file is not a 
recognized type. You can ignore this error and continue with the upgrade.

If you try to upgrade an IPS 5.x sensor to 6.0(1)E1, you may receive an error that Analysis Engine 
is not running:

sensor# upgrade scp://user@10.1.1.1/upgrades/IPS-K9-6.0-1-E1.pkg

Password: ********

Warning: Executing this command will apply a major version upgrade to the application 

partition. The system may be rebooted to complete the upgrade.

Continue with upgrade?: yes

Error: Analysis Engine is not running. Please reset box and attempt upgrade again.

If you receive this error, you must get Analysis Engine running before trying to upgrade again. This 
error is often caused by a defect in the currently running version. Try rebooting the sensor, and after 
reboot, run setup and remove the interfaces from the virtual sensor vs0. When it is not monitoring 
traffic, Analysis Engine usually stays up and running. You can upgrade to 6.0(1)E1 at this time. 
After the upgrade to IPS 6.0(1)E1, add the interfaces back to the virtual sensor vs0 using the setup 
command. 

Or you can use the recovery CD (if your sensor has a CD-ROM) or the system image file to reimage 
directly to IPS 6.0(1)E1. You can reimage a 5.x sensor to 6.0(1)E1 because the reimage process does 
not check to see Analysis Engine is running.
