I have a hEX S currently, but my ISP is now pushing more than 1Gb so I wanted to upgrade. I did some research and had some questions if anyone could answer regarding the RB5009UPr+S+IN (https://mikrotik.com/product/rb5009upr_s_in). I am going to list them in a numbered format so it's easier to list each number and answer if that is okay.
1. Would it make sense to use the SFP+ port for my modem connection, and then the single 2.5Gb port to a switch? Are there any downsides or slowness by utilizing the SFP+ port? Does anything get the speed cut down by using this, etc?
2. If #1 is a GO, is there a particular SFP+ module I should get with this?
Can I import my backup from my hEX S and have this ready to go instantly? Or do I have to do more work to restore all my settings correctly since it would be a different device?
Which kind of connection does your ISP provide?
Ideally the ISP modem/fiber converter would have also an SFP port and you could use a DAC instead of a RJ45 copper SFP (as they tend to run really hot, and this is no good in a passively cooled device such as the RB5009).
If this is not the case, you can maybe "reverse" the setup, i.e. use the 2.5Gb ethernet port to connect to the ISP device and use the DAC to connect to a switch[1]
Depending on what is on the other side.
Yes and no, a direct import is not advised, generally speaking, and besides the port number mismatch, making a new configuration (copying bits and pieces from your old hex S one) may be an occasion to review it.
No, at least here on the forum I have never seen anyone lamenting any slowness with a RB5009
It is too d@mn lite to use it as a door stopper, it could be re-used as a simple switch, or you could use the PoE out port to pilot a relay.
[1] this also depends, if plain 1 Gb connection on ethernet will become the bottleneck, you will have to update also to a 2.5 Gb capable switch
I have the S+RJ10 and this works fine. Sure it runs a little bit warm, but well within specs. Its running for years without any issues. At present my Internet line does not exceed 1Gbps
These 2.5Gbps LAN-ports always to me are a bit "hit & miss" to get it stable. At least you read quite often some issues with that.
Run the native 2.5G port to the ISP, and (if your switches will support it), the SFP+ port at 10G with opttical or DAC to them.
This gives full speed to the ISP, as well as extra bandwidth internally if you have anything else routing.
(Myself, it's the RB5009 to a CRS305 on optic, and then from there, optic to my CSS610 and CSS318s, and then gig to small clients, and 10G optic to servers.
The rb5009 is a nice device for this kind of setup.
The horror you mention comes about any time a large to small bandwidth interconnection is present with not enough buffering (usually when switching,) and it's a problem regardless of manufacturer or device. This can be present in various forms, and it requires proper planning and handling.
I would suggest the reverse arrangement: connect the 2.5G ethernet port to the ISP equipment, and use the sfp for interconnecting the rb5009 and a switch.
The "sfp getting warm" thing is not really a problem related to the sfp port itself, but rather to the 10G copper modules that run (in)famously hot. For this reason and others, I suggest avoiding them altogether if possible.
If the install was not sloppy, repulling 1 or 2 lines to optic is trivial.
(And why wouldn't he?)
10G on copper is STILL a solution in search of a problem . . . Unless it's recent, you would often need to pull better spec UTP anyhow, and the workload is the same . . .
Not sure why any heat would move to the switches, other than persisting in using RJ45 SFPs . . .
Yep, set aside the awful amount of cost for the SFP modules, if OP keeps everything cabled with ethernet and gets (just saying) a CRS310-1G-5S-4S+IN https://mikrotik.com/product/crs310_1g_5s_4s_in
(don't you like how the good Mikrotik guys make easy to distinguish models?)
filling the SFP cages with S+RJ10's, he would IMHO get as a side effect a small ventilated stove (useful in winter, not so much in summer).
$15 bucks is expensive? Not in my world . . . . And how many switches to trunk? OM4/OS4 fiber is pretty close in price to UTP as well . . . . makes very little sense to NOT change as I see it (esp if the UTP won't support 10G).
If the house is re-wired with fiber, it has a cost, (maybe where you live technicians with the right knowledge and tools to splice pigtails are free, around here is more like - if you find someone willing to do the work - around 25-35 Euro per each termination). but then the optical SFP's are cheap. (of course if you can manage to install pre-terminated fiber, things change)
Now that cheap splicers are a thing it is starting to be not-so-crazy to buy one, BTW, still we are talking of 500 Euro or so I believe:
If the existing ethernet is deemed good enough, each S+RJ10 is more like 60-65 bucks.
I just did mine. Attach pre connectorized fibre to the end of the UTP, and pull it through. LC to LC couplers on keystone plates. Zero splicing. Zero terminating. Zero need to hire some lugnut to do it for you IF the initial install wasn't an abomination. Took me maybe 20 minutes per run for a total of three . . . .
And, the SAME PROCESS to upgrade to 10G capable UTP if things are a bit older and the existing cable won't support it. (And optical doesn't cripple you like more copper would looking forward, isolation, etc.)
That depends entirely on how the old cabling was done, in many places pre-made terminated fiber won't pass inside the conduits.
Maybe because it seems like you pay a fee per word you write.
My claim (that remains) was that IF the ethernet cabling is maintained AND IF OP has to fill a SFP switch like the CRS310-1G-5S-4S+IN with 9 S+RJ10, the SFP modules alone will be more than 500 US$/€ that represents an awful amount of money (to me).
I assumed that a financial response to a financial comment would have been trivially associateable.
And yes, I absolutely loathe the amounts of what feels like excessibe verbal diarrhea than so many posts here waste time with (especially the "Artificial Imbecile" gaseous outpourings), so yes, I try to be terse as a kindness to fellow readers. Nothing bugs me more than having to plow through hundreds of lines to find the one or two that are actually relevant . . .
Considering that plenum UTP and glass don't require conduit (and my home is older, so just plain has none . . .wiring runs in attic and basement ceiling space . . . ) I dod overlook that (although it does come under "if the old installation isn't a mess" . . . it's not like an LC is very big . . .
I still feel that optical is a vastly superior solution though . . . where you can do it.
keep it as a spare and for a lab router. You can also use as a switch as suggested by @jaclaz
Just curious, what is the advantage of such a high speed internet connection, other than bragging rights? How much bandwidth do you consume per month? Is the current RB750Gr3 making things slow (that you can really notice)?
That horror story wasn't about the RB5009, it was about wireless. It said they only got higher speed when using a wired connection. And the RB5009 has no wireless option.
If I want to reserve the SFP+ for my LAN, do I get a 2.5Gb SFP+ module for it, and connect that to my switch? Or would that generate too much heat?, and a new switch that allows a DAC be necessary? The only basic 2.5Gb switch I have is straight ethernet.
