You can get PCM for a 60-day free trail.
To download go to
http://www.procurve.com/customercare/support/software/summarypages/pcm-j8991-0310.htmAfter the 60-day trail period, the number of devices that you can manage and also certain features would get limited.
You need to purchase license to get the full fledged features after that. Basically it is licensed by number of network devices managed and remote Agents required. There are three levels of license:
a) 50-device limited license plus 1 Agent, b) +100-device incremental license plus 1 Agent,
c) an unlimited device license and all supported Agents.
You would need to choose the one per your requirements.
You can get more details by following the above link..
