need to connect GSM7248V2 and a GS728TPP switch with a SFP CABLE

what product number should i ordered to NETGEAR to connect those 2 switch with a SFP or SFP+ Cable to link them up

 

i need those 24 port on the GS728TPP for ip phone so i must use a fiber cable to connect it to the network and i don't find the product i should order to do that.

 

Thank to help me.

Model: GS728TPP|ProSafe 24 ports PoE Smart switch with 24 POE+ ports, GSM7248v2|ProSafe 48 ports gigabit L2 managed switch

@vortexqc,

 

The SFP modules that are compatible to both GSM7248V2 and a GS728TPP are the AGM731F and AGM732F.  As reference, kindly check the last page of their respective data sheets below:

 

GSM7248v2 Data Sheet

 

GS728TPP Data Sheet

 

Kindly check below for more information about the AGM731F and AGM732F:

ok so the AGM731F will do the job the 2 switch a on the same rack, and for the fiber cable who goes in this adaptor

is there a netgear product number for this cable ? i only need 6 feet or less

Re: need to connect GSM7248V2 and a GS728TPP switch with a SFP CABLE

As both end SFP are plain SFP (no SFP+ on one end), you might have the possibility to deploy a simple an inexpensive SFP-DAC, like an AXC761 (1 m / three feet) or AXC763 (3 m/ ten feet).

 

Can @DaneA  validate this for thee two switch models/model lines please?

AGM731F is SFP+ tranceiver but in the documentation those 2 unit are only SFP will it work with SFP+ tranceiver ?

AXC761 is SFP+ will it work ? the 2 switch are SFP not SFP+

AGM731F is the NETGEAR ProSAFE 1000BASE-SX SFP GBIC Module - not requiring an SFP+ garage.

AXC761 is like all shorter ones a passive DAC cable, which in general works to connect two SFP+ ports (as a 10G link) or two SFP ports (as a 1G link). Very often, a DAC works for for SFP+ to SFP connections (obvious again as a 1G link), too. I've challenged @DaneA  because the DAC is not on the compatibility list officially for these switches (the DAC were introduced later than the compatibility lists were published!) - we know that the Smart Managed Plus and Smart Managed Pro don't enforce exact vendor and models (e.g. XS7xxT [SFP+] <-> GSxxx or GCxxx [SFP] are working nicely - but the Netgear Managed switches might be different. Probably @LaurentMa might shed some light here again, merci!

 Hi,

 

No, a 10G SFP+ DAC cable will NOT work when inserted into an 1G SFP port, it won't be recognized and there is no way to establish a link at 1Gbps using it.

 

Either the 1G SFP ports on both of your switches receive a 1G SFP transceiver such as our AGM731F, or a MSA-compliant 1G DAC cable. I don't think this is common, and you might have trouble finding any. I would rather insert a 1000BASE-T RJ45 SFP transceiver such as our AGM734 in both switches' SFP port, and use CAT5E or better cable between the two.

Edit: Ignore m previous text, of course you are correct!

Yes, for the 1G range the AGM734 are an affordable alternative to short range Multimode fiber modules, indeed.

Hello, my response is valid for any switch equipped with 1G SFP ports - the 10G SFP+ modules (fiber transceivers) or DAC (cables) can't be recognized by the 1000BASE-X SFP PHY or port, no link possible.
