US Patent 10348327 Technologies for providing power to a rack

A rack for supporting sleds includes a pair of elongated support posts and pairs of elongated support arms that extend from the elongated support posts. Each pair of the elongated support arms defines a sled slot to receive a corresponding sled. A power supply is attached to an elongated support arm of each pair of elongated support arms to provide power to a corresponding sled. The power supply may include a chassis-less circuit board substrate that is removable from a power supply housing coupled to the corresponding elongated support arm.
