Hi,I did some research and compared it with another model. There is a difference that PC2824 does not control I2C initialization during POST. The link here is on page 50 [URL] for example, if PC 5224 is, I saw that it initialized I2C during POST. Page 11 [URL] I think that is why you received this warning on PC2824 during the HOST test. So I don't expect it to pass this test Let us know if it helps!
I ran the I2C "HOST" test on a Dell PowerConnect 2824 and got a failing result.  Being new to Dell switches, I could imagine some hardware configurations where this test wouldn't be expected to pass on some models. The pertinent serial output is as follows      Should a PowerConnect 2824 pass this test?
