We have two racks in a datacenter, currently powered by two independent sources. All devices are distributed across four different power extenders, and a few critical ones are first connected to a UPS and then to one of the power extenders.
Our wish is to protect us from: Device 1 connected to a power extender causes short-circuit, this killing the fuse of the branch and all devices on that branch go offline.
Do you have any ideas for best arrangement of both racks to have as good power redundancy as possible? (UPS already made a problem, after an outage it made short circuit to whole branch).
