can SFP-10G-SR works with 3850 moduel NM2-10G G1/1/1?

[Herman2018]

Hi, we have one C3850 with one network module NM2-10G. Currently the 2x10 SFP are already inserted into T1/1/3 and T1/1/4. So two spare ports G1/1/1 and G1/1/2. Can we use SFP-10G-SR for this 2x 1G ports? can anyone pls advise ? thanks in advance.

Supported combinations of SFP and SFP+ modules: Slots 1, 2, 3, and 4 populated with 1-Gigabit SFP modules. Slots 1 and 2 populated with 1-Gigabit SFP modules and Slot 3 and 4 populated with 10-Gigabit SFP+ module.

Can we use SFP-10G-SR for this 2x 1G ports?

That is for 1GB SFP Only - you can not use 10G SR on that module you get gbic error since its not supported.
