You must log in to Cisco.com using an account with cryptographic privileges to download software. The 
first time you download software on Cisco.com, you receive instructions for setting up an account with 
cryptographic privileges. 

Do not change the filename. You must preserve the original filename for the sensor to accept the update. 

To upgrade the sensor, follow these steps:

Download the appropriate file to an FTP, SCP, HTTP, or HTTPS server that is accessible from your 
sensor.

Use IPS-AIM-K9-6.2-2-E4.pkg to upgrade the AIM IPS, IPS-NME-K9-6.2-2-E4 to upgrade the 
NME IPS, and IPS-SSC_5-K9-6.2-2-E4.pkg to upgrade the AIP SSC-5. For all other supported sensors, 
use the IPS-K9-6.2-2-E4.pkg upgrade file.

You must upgrade IPS 6.2(2)E3 to IPS 6.2(2)E4 using the engine upgrade file 
(IPS-engine-E4-req-6.2-2.pkg) because you are upgrading the engine only. You cannot use the 
IPS-K9-6.2-2-E4.pkg upgrade file to upgrade from 6.2(2)E3 to 6.2(2)E4. Engine updates may or may 
not cause the sensor to reboot. 

Log in to the CLI using an account with administrator privileges.

Enter configuration mode.
