Energy Efficiency of GS19.. Series
I'm currently running a bunch of enterprise switches in a home environment for training purposes. Therefore I'm interested in low energy consumption and noise levels (so also low heat dissipation), but still essential enterprise functionality (VLAN, QoS - especially with VoIP, data flow).
I already have a GS1910-24 running, which is passively cooled and uses sFlow (which is nice feature, but I've not found any good tools to visualize).
This one together with a Cisco switch should be replaced and I'm attracted by the Nebula cloud monitoring feature, which I expect would be a good successor for sFlow visualization (not that detailed, but better overview).
Since GS1910 is EOL, I have to decide between GS1900 and GS1920 (still staying on 1000BASE-T - 10GBps is still wasting energy).
Cisco is providing in their data sheets energy usage based on 0%, 10% and 100% traffic and a weighted average. This is especially interesting for PoE switches, since the total max. power consumption is not reflecting the real scenario with just a few 4W devices connected and so no efficiency metric.
So, I'm curious if you have more detailed power metrics especially for
- GS1920-8HPv2 (heat dissipation is insanely high compared to GS1900-10HP)
GS1900 would be a trade-off since no Nebula cloud, but more efficient.
Influence of SFP modules would be good to know as well (since spec says 3.3V with 300mA, I guess 1W is calculated per SFP into the max consumption usually?)
By the way, why has GS1910 series been discontinued?
Welcome to Zyxel community!
Here is the desired power metrics sheet of GS1900 & GS1920 series for your reference.
In regards of SFP module influences on power,
According to official data sheets of Zyxel transceivers, your speculation about average 1W consumption per unit is basically not far.
As for GS1910, it's EOL due to the release of its successor, GS1920 series.
Sorry, can this be moved? - I've accidentally posted to "Ideas".
Alternatively, please treat as datasheet improvement idea...0
One more question: Are the numbers from your list including SFPs? I would guess it is with all ports connected with 1Gbps devices, right?0
Our full load test is where all copper & fiber ports inserted, SFPs are included.
