Hey so I was wondering if there is a way to hook up 2 mega powers like 1 as a slave and one as a master or primary and secondary. I have 2 MegaPower 48's but only 1 is in use. I just added another dvr and now would like to be able to call that new dvr to my monitors but my first megapower is completely full. Can i add my second megapower to expand my first megapower.
