Hello all

I have a huge problem interconnecting the 3 x netPower Lite 7R via SFP interface.

SFP Modules tested (have 8 modules on hand:
S-85DLC05D - MM with 3m patch cable (input AB output BA), 1m the same setup.
S-31DLC20D - SM with 2m patch cable (input AB output BA)

Connection scheme:
netPower Lite 7R (CSS610-1Gi-7R-2S+OUT) : SFP => MM or SM => SFP: netPower Lite 7R (CSS610-1Gi-7R-2S+OUT) : SFP => MM or SM => SFP: netPower Lite 7R (CSS610-1Gi-7R-2S+OUT)

there is no link on between netPower 7R devices.

Previously I've tested the SFP modules between hEX S and RB4011iGS+5HacQ2HnD-IN and CRS112-8P-4S-IN they work really well, no configuration needed.
Also if netPower 7R lite is connected to either of devices above via SFP the link becomes operational. But if we try connect between two netPower 7R devices via SFP it doesn't establish the link.

What I've tried:
disabling auto negotiation, setting 1G, 100MB, 10MB. No luck.

Any suggestions from the members or Mikrotik staff?

Firmware is still in Beta. There's still tons of bugs and we're all waiting on a stable version. The CSS610-8G-2+ is the same chipset. The SFP ports have been the biggest issues for others.

See thread right above yours or click below for more info.


And here's another thread with same exact switch regarding SFP issues.
