Upgrade Catalyst 2960-X with flexstack C2960X-FIBER-STK to do network

[Billycisco]

HI there

i was wondering if i can upgrade my 2960-X : Catalyst 2960X-48LPS-L  with a C2960X-FIBER-STK or a C2960X-HYBRID-STK to do some network operations (from the sfp+ ports) with a non-cisco device ?

Thank you for your lights .

Regards.

non-cisco device - means other vendors? No that is not possible.

Unless the 2960X was sourced from a reputable or a known Cisco distributor, I would not touch it.  

2960X is the most widely counterfeited product sold in the market.  

The only time operators found out they got a counterfeit is when the IOS got upgraded and bricks the switch.
