I have updated RB4011 and CRS328-24P-4S+RM and the SFP+ (DAC (S+AO0005)) Rx FCS and Rx Align errors on RB4011 side is solved. Thank you!

The red is not blinking just on with the blue one. The device is dead and i got a replacement from the dealer.

Hi Guys! I have an Audience and after a reboot the red and blue led is on and the device is dead. The LED of LAN ports don't light. I have tried to use another power supply, and POE Switch without any result. I can not put the device in netinstall mode. Is it a well known symptom and/or a dead device?

I have installed a Mikrotik CHR router on Azure and connected to this CHR -> L2TP and EoIP over that L2TP. It worked.

I agree with you! But my tubes in the wall are full and it was a quick and dirty solution If i will have to interconnect my equipments in the rack than the optic modules will be the solution.

My CRS328 has the following POE loads:

- 2 pcs CAP AC
- 1pc HAP AC^2
- 4pcs Hikvision sec. cameras
- 1pc Raspberry PI 3B
- 1pc RB4011
- 1pc RB3011

The System Healt:

It is less than 10 meters CAT5E without shild.

I can not use fiber because of my existing cables. The only one problem with RB4011 is the high working temperature of the SFP+ module.

Yes, i am using S+RJ10 modules between RB4011 and CRS328.
