Go to the main IPS download page:

Find the following section:

Network IPS/IDS Sensor Appliances

Version 5.x (IDS/IPS 42xx Appliances)

Click on the:

Latest Service Pack, Minor, and Major Updates link.

Download and install: IPS-K9-maj-5.0-1-S149.rpm.pkg.

Once that upgrade is done, then download and install: IPS-K9-sp-5.0-3.pkg

Now you just need to ensure the latest signature update is on the sensor.

Go back to the main download page and click on the Latest Signature Update link.

Download and install the latest signature update (currently IPS-sig-S183-minreq-5.0-1.pkg)

Each update has it's own readme file with instructions for installing the updates (if you are already running 4.1, then installation is nothing new).

For User Guides go to the main page for IDS/IPS docs:

And click on the link for version 5.0 docs.


thanks for fast replay i try the first file


but i got error message during update

incompatable hardware

do u know what is this error

Execute "show version" and see what platform is reported. Verify that it reports that your are running an IDS-4235 and not an IDS-4230.

(NOTE: Some users have confused the 2 and did not realize that the IDS-4230 is Not supported in version 5.x. At one time there was a program in place for upgrading from a IDS-4230 to a IDS-4235, but I am not sure if that program is still in place.)

If it is a IDS-4230 (or IDS-4220 even) then contact a Cisco representative about upgrading your hardware.

If the platform is not reported in "show version" then the upgrade can not be installed.

Verify that this is a Cisco purchased sensor, and that no user modifications of hardware has been done (like replacing CPUs, memory, or anything else without an official Cisco IDS part number).

Some users have attempted to upgrade their sensor hardware with off the shelf memory and CPUs and this confuses the sensor code that determines the type of platform. Often these off the shelf upgrades can lead to other issues on the sensor, so their use is unsupported.

If no changes have been made to the hardware and "show version" does not show the platform, then there may be a hardware problem with your sensor. Contact the TAC and ask for their assistance to help further diagnose the issue. You may have to RMA the sensor.

If "show version" does show the correct platform, and you still get the error during upgrade. Then you can post a copy of the "show version" output, as well as a "dmesg" output. (You would need to login as the service account to get dmesg output)

And I can take a look.


thanks for your interest

please find attached o/p of ids which u ask for

for both sh ver and dmesg



Nothing looks out of place from what I can tell.

Can you try the upgrade again so we can see the complete error message.

Within the CLI do a "show version" first, and then "conf t" followed by the "upgrade" command. So we can compare the the "show version" output to the "upgrade" error all in the same CLI connection.



thanks for your help i can upgrade now do u know the error was when i upgrade i type the upgrdae file name in small letters but some one told me to type the file charachers as i got from cisco but i have a strange problem after i do sh ver on ips i got this o/p

sensor# sh ver

Regarding the "No license present" message:

Beginning with IPS 5.0, an IPS Subscription Service License is required to install signature updates.

You can request an IPS Subscription Service License for all sensors covered by a maintenance contract at this URL:

To manage your maintenance contracts use the Service Contract Center found at this URL:

With the initial release of 5.0, the first several signature updates will be released without the license enforcement to allow you time to get your maintenance contracts in order and your sensors licensed. However, it is recommended that you get your license and install it as soon as possible in order to avoid interruptions in your signature updates.
