[AusNOG] ATS vs STS & recommendations?

[Mark Tees]

Not sure about Global Switch but from memory power at Equinix (at least in
some parts of SY1/2) goes customer feed primary -> big STS -> UPS A/B ->
ATS -> grid power or genset.

Same for customer secondary feed but via different STS/UPS.

You could see the large transfer switches on SY1 floor I think.
