As I'm searching for a good 24-port router with VLAN and IGMP support, I asked a colleague for his preferred choice and he warmly recommended the CRS328-24P-4S+RM. So I ordered one and I have to say I am very impressed with the feature set. Very nice device at an interesting price point, congratulations Mikrotik!
However, I'm very surprised about its idle power consumption. I've measured it at 25W idle power consumption (!) when nothing -- absolutely nothing -- is connected to it. I've tried to disable every port's PoE support, and I've even disabled all ports altogether, but it still consumes the same amount This is on RouterOS 6.42.5, which is not the most recent release, but nothing in the release notes hint at an improvement in this area in more recent releases.
We're talking about a private home environment here, so what may be acceptable in a business environment is a no-go for me. I mean, come on, 25W? That's 3x the idle power consumption of a modern PC. That device alone grabs a whopping 10% of my whole house's power consumption
Are there some other settings I could try to tweak?
Is there a way to disable PoE altogether for a quick test to see whether that is to blame?
Anything else I could try to get the device down to reasonable power draw?
Does the CRS326-24G-2S+RM consume less in idle? How much does that model need? (Yeah I know it doesn't do PoE, but it might be an alternative for me nevertheless.)
Any other suggestions?
