Hi Rick An 60601-1 approved PSU will pass 60950 requirements for safety. But the router is not automatically in complians with 60601-1 just because it is powered from a medical grade PSU.
Yuo can connect the output from the secondary to earth, but this will have great influence on how the connected medical devices shall be designed. It is absolutly best to make it float, when looking at medical electrical safety.

Sorry for so many question at once and I am researching this in several ways, but I know and trust this group’s experience and opinions. Want to change an approved ITE 5 port Ethernet router switch device with external ITE power adapter to medical grade power adapter. This is a desk top type power adapter with IEC 320 appliance coupler. Is it wrong (or maybe how wrong is it) to assume that a 40 watt AC-DC 12 VDC out power adapter meeting 60601-1 (safety) and 60601-1-2 (EMC) will meet or exceed 60950-1 (safety) and EN55022 Class B/EN 55024 (EMC)? Can the secondary be earth grounded on a 60601-1 power adapter (i.e. green/yellow wire from input tied to secondary)? Does harmonic (61000-3-2) and flicker (61000-3-3) apply to medical devices if over 75W? Are WEEE and RoHS exempt from medical? Is there anything else I should keep an eye out for in this conversion?
