SFP+ RJ45
I am running a 110P on a bonded trunk pair from a 728XP. I was hoping to use the 1Gbps SFP ports on each of the switches to do this and keep the PoE ports free. However, neither one of them likes the...
OK, the cheap SFP to RJ45 adapters work if you only use them on one end. The other end must go into a normal RJ45 port. No idea about the official ones, but this is good enough for now. At least I can use all 10 ports on my GC110P.
Haven't used the two SFP+ ports for the modules on the GC728XP by error? Asking because of the subject "SFP+ RJ45" - SFP+ ports ... and these SFP+ ports don't support any kind of speed negotiation so GbE SFP modules can't work reliably in an SFP+ port.
Sorry about the confusing title. I am trying to use them in the 1G SFP ports. I'm still not getting consistent results so probably best avoided, but it means that the GC110P is really only an 8 port switch for most people.
Ok. Reason asking was that I'm trying to configure a similar set-up - with no-name/FS SFP 1 GbE copper modules in a GC510PP linking to another Netgear switch with SFP ports in a 802.3ad LAG - but all managed within Insight. And similarly struggling on unreliable connectivity results, too.
I currently have a GC728XP and two of GC110P. The GC110Ps are each running on a LAG bonded pair into the GC728XP, which then has a 10Gb SFP+ DAC into an M5300 L3. I am not using the SFP ports on the 728 for the 110s, just the normal ports. One of the 110's is using the cheap SFP adapters. It seems happy but there is a red circle slash on one of the SFP ports in the app - not sure what that means. The other 110 I have not been able to move onto the SFP ports, even one SFP port plays up. Haven't had a chance to do a lot with it because people are using that one during the day. Everything is currently on local management except that one 'test' 100 that is using the SFP ports.
I now have this running on switches with firmware 1.0.4.6 and all settings still on factory defaults - except for the LAG. So 2 adapters on a GC110P and 2 adapters on ports 25 and 26 of a GC728XP. The only obvious setting difference in the GUI on the new firmware is that the Frame Size default is 1518 instead of 1500. The switches that don't work are still on firmware 1.0.2.11.
