Hi,
last time I has configured a RB2011 (6.41.2). When I disabled the SFP interface the blue LED switched off.
Today I configured any older RB2011 (6.40.1) and there I was not able to switch off the SFP LED.
Both RB2011 has no SFP adapter in the slot.
The easy way: Use a bit of black DUCT tape. Works perfectly.
The hard way: wait till someone form Mikrotik support will answer.
I wish i could to disable that light.
Alternatively, a black marker pen will do the trick !
@Mikrotik: A software solution for this “issue” would be fine.
Mail support.. the forum is no official support channel.
Ok, I did.
