Question on Cisco C9300L-48P-4X 48 PoE+

[EF_777]

Hello,

Can someone please tell me if C9300L-48P-4X 48 PoE+ switch's fixed 10G up-link ports support 1G sfp's too?

Hi,

That model supports only 4x 10Gig.

Hello,

according to the hardware installation guide linked below:

--> The C9300L switches provide fixed uplink ports that support 10G and 1G SFP/SFP+ modules.

Hi Georg,

The data sheet (table-1) has this switch as fixed (C9300L-48P-4X). So, not sure which document is correct :)

As per my knowledge, it does not support 1GB, it has fixed 10GB.

Are you sure about that? The Transceiver Compatibility Matrix shows support for both 1Gb and 10Gb SFPs on the 10G fixed uplink switches (i.e. C9300L-24P-4X-E). I am going to have my SE check with the BU just to confirm before we buy any.

The 9300L 48P-4x supports 1G SFP Modules: I am using GLC-SX-MMD model to use the uplinks with 1Gb speed
