Uplink SFP

[Eddie01]

Hi,

I have a site that is migrating their present Catalyst 3750 switches to MS225 and 250, my question is. Can they reuse their present SFP's?

Thanks

GLC-SX-MMD

@Eddie01 : yes GLC-SX-MMD is supported in Meraki. Go ahead 

[Eddie01 · Accepted solution]

Thanks!!

@Eddie01 just to caveat what @Inderdeep a has stated. Yes, those SFP modules should work. However, they are not actually supported. What this means is that if you log a support request and support believe the issue may be the SFP module they may refuse to assist until you have a supported SFP module in the switch (admittedly this is rare, but I have heard of it occurring). This is the same support that applies to any third party SFP, and yes I agree there is a certain craziness in Cisco SFPs not being officially supported in Meraki devices, but that’s what it is.

You can check the officially supported modules here https://tmgmatrix.cisco.com/ or here https://meraki.cisco.com/lib/pdf/meraki_datasheet_sfp.pdf and the support policy provided here, https://documentation.meraki.com/MS/Other_Topics/MS_Switch_SFP_and_SFP__Overview

Also note that if they are 3750's, they are probably 15 years old.  Do you really want to re-use 15-year-old IT kit in a new solution?

Bin them.
