First of all, I'm a web designer, not a network engineer, so simple answers are appreciated! We have someone coming in to sort out the network in the office and he has asked whether our Dell PowerConnect 3524 is in fact a 3524P Model. On the front of the unit, it just says 3524, but so do all the images I've seen of the 3524P model. Is there a way I can tell which model we have?
According to this, the P means PoE http://www.dell.com/downloads/global/products/pwcnt/en/pwcnt_3500_spec.pdf
You could also search support.dell.com with the serial number on the switch and it should tell you exactly what model it is.
