Do CRS305&309 support other brands' RJ45 SFP module?

Sat May 04, 2019 12:40 pm

Hi all,
I just bought two CRS switches and some RJ45 SFP modules.
And I found the switches are not compatible with them.
The switch can show the model number, serial number and date in SWOS website. But no link, no LED blinking.

Ubiquiti UF-rj45-1g: not work
Avago ABCU-5730RZ: not work
Avago ABCU-5731RZ: work fine

I put the modules in a Ubiquiti switch and all work fine.
I also tried to disable Auto-Negotiation in CRS bud still didn't work.

Any method to improve compatibility?
Thanks.

Hi
just wanted to confirm that i have the following in my CRS326-24G-2S+
Finisair FCLF-8521-3
and they are working.

There is the need to fix the speed to 1GB.

But the GUI is having a strange behaviour.
2 SFPs are plugged in and fixed speed set.
1 SFP with a device connected.
both SFP show the same traffic in the Web and WinBox Gui

Strange

Simple solution. I buy the Mikrotik SFPs that are specified to work with the device.
RB750Gr3, RB750r2, CRS326-24G-2S (in SwitchOS), CSS326-24G-2S, CSS106-5G-1S, RB260GS
Not sure if I beat them in submission, or they beat me into submission

The more interesting part of this is that even original Mikrotik SFP RJ01 1G show the same behaviour (showing traffic on SFP which has no cable plugged in ) when the speed is fix set to 1G.

Mmmh does this mean working as designed ??
