Question about TP-Link Tl-Sm321b

I have been using the TL-SM321B in an MC220L with an Init7/Fiber7 glass subscription for almost 5 years without any problems. (this combo was also their standard config proposal or hardware bundle offer) So at least in terms of hardware, the question can be answered with YES... I can't say whether Sunrise has tinkered with any of its own specifications, but I think this is less likely to be the case.
