We have about 4 servers connected to an APC UPS. The UPS only has one
UPS connection. So my question is, in a power outage how do i get all
my servers to safely shutdown? Do i run a USB hub? Do i write a script
on the one machine connected to turn off all the other machines? I'm
confused.
what Michel said...
I want to add, a USB hub would not work... USB is a one master, many
slave star bus. a PC is the master,, a device like your UPS is the
slave. you can't connect two masters to the same USB*
*there are special USB to USB network cables, these are actually two
slave ports with some network glue in the middle, this doesn't violate
the rule above
