Lemosa patchbays and earthing the sockets

[salomonander]

Hey there,
I have seen two ways of dealing with earth connections of lemosa sockets on patchbays:

- the sockets are isolated from the frontpanel, but each socket has a solder lug. All lugs are connected via a solid silver wire which is conncted to a central earth point

- the sockets are not isolated and get their earth connection directly via the frontpanel

Is one preferred over the other? Or does it not matter at all?

Thanks!
