Same SFP Model and Part number, different design and serial number syntax.

[its_Tricky83]

Hi All, 

I'm not sure if this causes any issue what-so-ever (Maybe someone can confirm?) but we recently purchased some more official Meraki SFP's, only to find the design of the SFP's have changed, along with the serial number syntax; and the theoretical speed has dropped a bit!

Original SFP's purchased a 18months ago, as shown in the Dashboard!

• SFP module Meraki - 1000BASE-T: 1.3 Gbps (Part 600-22100, Serial: Q2KR-CSCH-Q### )

Newer SFP's purchased February 2022, as shown in the Dashboard!

• SFP module Meraki - 1000BASE-T: 1.2 Gbps (Part 600-22100, Serial: 2130###### )

Here's a photo showing the design difference:

We'll be using these in a VRRP configuration, so I'm hoping everything works just fun.

Just putting this post here in case others notice the same and have anything to chime in with!

Suppliers change over time, especially in these challenging times with supplier and inventory issues. Anyway, it should work fine. I've used mixtures of transceivers many times.

Do both click home properly in the Meraki device, I had a problem with MS355s where many GLC-T derivatives wouldn't latch, or if they did, wouldn't come out!
