Do we need to buy a separate IOS image for Cisco switches? For example, I will buy the WSC3650-8X24PD-L. Am I right to assume that this switch has a built-in IOS image, and I don't have to buy a separate image if not required?
Next question is, If I want to buy an image like the S3650UK9-166... Is it compatible to the WSC3650-8X24PD? Is this image falls on the IOS-XE 16.x series?
Thanks!

Hi there,
The different platform architectures require specific software binaries. A 2960X and 3750X for example both run IOS but the software is not interchangeable.
When you buy a switch it will be switched with the recommended image at time of manufacture.
To gain access to subsequent new releases you will need a Cisco support contract, either through a third party or directly with Cisco.
cheers,
Seb.

You don't buy the software images. All of the images produced for a platform are made available to you through a support contract which you buy.
Sometimes when you a receive a switch it may have sat on a shelf somewhere for a very long time as such the image running on it is equally as old. The older an image the vulnerabilities or bugs it will be susceptible. It is good practice to keep a close eye on:

Also, find the software download page for your switch:
https://software.cisco.com/download/home/284850385/type/282046477/release/Denali-16.3.6
...and use the 'Notifications' to subscribe to periodic updates.

It's been a long time since I was involved with price lists and BOMs. Typically you would list the hardware and any additional part-numbers representing a specific license ie, IPBase, LANBase, IPServices.
The only reference I can find for S3650UK9 is a universal licence, with the 166 indicating the IOS-XE v16.6.x train.
I suspect they have added S3650UK9-166 as a way of quantifying the value of the software. Maybe?? Unless of course it means you have a support contract for access to v16.6.x software.
I've seen third party suppliers try to refuse support on hardware which is running a software train which the hardware was not running when it shipped!
cheers,
Seb.
