Abstract

Technology is provided for a server platform with a continuously powered server sled. The server platform includes a cubby chassis including partitions defining a plurality of sled positions. A power tray is located in a corresponding one of the plurality of sled positions and a server sled is positioned on and continuously powered by the power tray. The power tray includes a tray chassis having a tray sidewall and a tray bottom wall. A pair of elongate conductors extend along the tray sidewall. A tray connector is mounted on the tray bottom wall and is in electrical communication with the pair of elongate conductors. The server sled includes a sled chassis having a chassis sidewall and a chassis bottom wall. A side-plane printed circuit board is mounted to the chassis sidewall and includes a pair of conductive elements positioned for sliding contact with the elongate conductors.

First claim

What is claimed is:

a tray connector mounted on the tray chassis and in electrical communication with the pair of elongate conductors; and

a device sled positioned on the power tray, the device sled comprising:
a sled chassis having a chassis sidewall and a chassis bottom wall;
a chassis panel mounted to the sled chassis; and
a pair of conductive elements mounted on the chassis panel and positioned for sliding contact with the pair of elongate conductors.

2. The device platform of claim 1 , wherein the chassis has a power input connector configured to receive power from a component rack, and the chassis includes at least one connector corresponding to the sled position connected to the power connector, and wherein the tray connector is mated with the at least one connector.

3. The device platform of claim 1 , wherein the pair of elongate conductors are disposed on a conductor support.

4. The device platform of claim 3 , wherein the conductor support is spaced apart from the tray chassis.

5. The device platform of claim 4 , further comprising a conductor guide mounted to the chassis panel adjacent to the pair of conductive elements.

6. The device platform of claim 5 , wherein the conductor guide includes a pair of opposed grooves adapted to slideably receive the conductor support.

7. The device platform of claim 1 , wherein the pair of conductive elements are spring biased toward the pair of elongate conductors.

8. The device platform of claim 7 , wherein the pair of conductive elements each includes one or more fingers.

9. A server platform, comprising:
a cubby chassis including one or more partitions defining a plurality of sled positions;
a power tray located in a corresponding one of the plurality of sled positions, the power tray comprising:
a tray chassis having a tray sidewall and a tray bottom wall;
a pair of elongate conductors extending along the tray sidewall; and
a tray connector mounted on the tray chassis and in electrical communication with the pair of elongate conductors; and

a server sled movably positioned on the power tray and movable relative to the power tray between stowed and extended positions, the server sled comprising:
a sled chassis having a chassis sidewall and a chassis bottom wall adjacent to the tray sidewall and tray bottom wall, respectively;
a vertically oriented side-plane mounted to the chassis sidewall; and
a pair of conductive elements connected to the side-plane and positioned for sliding contact with the pair of elongate conductors, wherein the pair of conductive elements are in continuous electrical contact with the pair of elongate conductors when the server sled is in and moves between the stowed and extended positions.

10. The server platform of claim 9 , wherein the cubby chassis has a power input connector configured to receive power from a component rack, and the cubby chassis has a plurality of cubby connectors corresponding to each of the plurality of sled positions connected to the power connector, and wherein the tray connector is mated with a corresponding one of the plurality of cubby connectors.

11. The server platform of claim 9 , wherein the pair of elongate conductors are disposed on a conductor PCB.

12. The server platform of claim 11 , wherein the conductor PCB is spaced apart from the tray sidewall.

13. The server platform of claim 12 , further comprising a conductor guide mounted to the side-plane and surrounding the pair of conductive elements.

14. The server platform of claim 13 , wherein the conductor guide includes a pair of opposed grooves adapted to slideably receive the conductor PCB.

15. The server platform of claim 9 , wherein the pair of conductive elements are spring biased toward the pair of elongate conductors.

16. The server platform of claim 15 , wherein the pair of conductive elements each includes one or more fingers.

17. A server platform, comprising:
