```auto
Product name: cnMatrix EX2028-P
CNS Software Version: 3.2.1-r5

```

I was wondering if it was possible to upgrade the switch’s image as mentioned in [the documentation](https://d1okf4ta8xniw3.cloudfront.net/original/2X/f/fd2012846d720e4bd4b1182dfe6aaa34bd0df8e9.pdf)

**HELP!!!**

Isn’t the idea of posting for help in this community that will help future users who get the same error and can help him/herself by seeing a proper response to resolve the issue?

By contacting the support team, the help would be private. Unless the problem can’t be solved publicly, why choose the private route?
