M4250-26G4F-PoE+ showing fiber ports as SFP instead of SFP+
Firmware Version 13.0.4.23 AV UI Version 2.2.7.36 Boot Version 1.0.0.12 Hello, everywhere I check the specs for this switch, it indicates that the 4 fiber ports are 10G SFP+ W...
- Hello, this switch has 4 x 1G SFP ports, please check the datasheet here?

With the latest firmware, only 1G transceivers can be used. Did you use 10G transceivers before? I am afraid it was wrongly showing 10G speed, but actual speeds were 1G only, as the ports are 1G.
You can use the XF models (SKU numbers with a "X" at the end for 10G uplinks (SFP+)
Please let us know!
Hi Denny,
No worries, let me tell you:
The M4250-40G8XF can accept 10G transceivers and 1G transceivers. It will detect the speed of the transceiver and automatically do 10G or 1G.
The M4250-26G4F can only accept 1G transceivers, and it won't be able to use 10G transceivers.
10G SFP+ ports accept 1G and 10G transceivers, and the speed is negotiated accordingly.
1G SFP ports accept 1G transceivers only.
I hope it helps!
