Re: 10GB SFP+ recognized as 1GB - Question [SOLVED]

Hey, 3011 is only SFP capable: see https://i.mt.lv/cdn/rb_files/RB3011UiAS-160307123613.png So max is 1gb Thanks, actually I'm embarrassed since I had a look at the block diagram several times and thought even though the channel only provides only 1GB to the CPU it should have a 10GB connection. Bu...

10GB SFP+ recognized as 1GB - Question [SOLVED]

Hi,

I do have a RB3011UiAS and a CRS326-24G-2S+ connected via a 10GB SFP+ DAC. Even though both ends are forced to 10GB full duplex they are only shown as 1GB connection within Winbox. The CLI though shows "speed=10Gbps".

Anybody experienced that? What is the truth?

Regards,
Starbug

Re: CRS328-24P-4S+RM - 24x7 fans or temperature sensitive?

I agree, that likely the CPU won't need the fans, nevertheless MikroTik does control the fan speed via the CPU temperature.

I also agree that I you don't find another POE switch with similar features/performance at that price point. I likely will give the Noctua fans a try.

Re: CRS328-24P-4S+RM - 24x7 fans or temperature sensitive?

What's even more strange, the same CPU (fanless) is running in my CRS326-24G at 69°C average. Who was so anxious about the CPU running at 41-42°C to have the fan kicking in at high speed of approx. 4.500 rpm. Why don't just carefully increase the fan rpm starting at 500 rpm or so at a higher CPU tem...

Same here, just having the CRS connected on one port to another switch it runs around 38-42 °C with the fan turning on and off all the time.

Very annoying. I rather prefer the fan running all the time or which would be less annoying.
