hEX PoE (RB960PGS) Problem after 6.49.4 > 7.1.3 with SFP

Hello!

We have a hEX PoE (RB960PGS) with 6.49.4 (+ Firmware) running with a pair of S-3553LC20D - other side is RB3011UiAS. Both sides up, both sides show all values ... running well without any problems.

Then we ran the Update on both sides. RB3011UiAS is ok with 1310.00 nm. But RB960PGS has

(1) no values

(2) the Link is up, bit toggels from time to time.

Is S-3553LC20D not completely compatible with 7.1.3 - no tested jet but RouterOS is stable ?

Flash File Space is 24% used (what ever is on it, not shown) and the rest of 16 Mbit is not enought to step back to 6.49.4 - location is not on our side ... How can we solve?

Please help,
Grüße Stefan

No idea about SFP module misbehaviour.

Re downgrade: it should be possible to downgrade ROS following this procedure:

1. copy appropriate .npk file (e.g. routeros-mipsbe-6.49.4.npk) to files section.
   Make sure you don't push it to flash/ directory, leave it in root directory. On devices with small flash disk, but decent RAM size, root of file storage is actually RAM disk
2. execute /system/package/downgrade
3. reboot device

Essentially follow the instructions for downgrading ROS ... the essential thing is to leave npk file in root of file storage (i.e. in RAM disk).

Hello!

We will try to roll back. I'll give you a feed back about it ...

To Mikrotik Bug Report:
We have rebuilt the setup in our lab.
This behaviour is everytime the same on different Harwdare: SFP S-3553LC20D is not working with 7.1.3 !

Rollback done.

SFP S-3553LC20D works NOT on 7.1.3 with

exemplary:
960PGS
CRS112-8P-4S

but with 6.49.4 again !
