I bought one piece SFP+ DAC 1 meter. It functions perfectly when connected with two Netgear switches, but it won’t work when I change one end to NAS (Network Attached Storage).

Solution:After our checking, NAS device is 10Gig optical port and supports SFP+ DAC. Please check if the Netgear switch is with 10Gig optical port. If not, the SFP+ DAC cable can’t connected as the data rates of two ends are different.

Tips:Confirm the same data rate of two end devices before make the connection.
