Hi, long time lurker now posting. I received my new Late 2015 5k iMac yesterday, i7 16GB ram M395X and 1TB Flash drive. Now I have all settings in power turned off so no Wake on network no power Nap and hard drives set to stay on as ~I have a 3TB external spinner that seems happier spinning and sleep set to 15mins. I have noticed though that when the iMac goes to sleep the Ethernet port stays powered, but on my Netgear R7000 the port turns amber so only at 10/100Mbs not the usual 1000Mbps All other Macs I have had don't leave the Ethernet port powered when in sleep mode, but is this normal for a ssd model? I have tried resetting power the settings but the Ethernet port still stays powered.I have a canon printer connected wirelessly, and a APC UPS and headphones plugged in. Any help would be greatly appreciated. Apart from this oddity its a great machine with a good screen totally silent and lightning fast. The Ethernet port powers up fine out of sleep as well.
