What is more ironic is that in the net room there is this huge UPS that takes AC power (220V actually) and converts it to 12V. It uses that 12V to charge batteries. The batteries then power an alternator that converts it back up to 110V which goes to the racks. Where the units I just mentioned convert it back down to 12V and 5V.

There are now some UPS systems that deliver high voltage DC to the computer, which then converts it down to the voltage required by the system. This eliminates a couple of conversion steps. The telecom industry has been running on 48V DC for a very long time. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
