Intel® Server Platform SR6850HW4 TPS

Server System Chassis and Assemblies

3.1.2 Slide Rails

The Server Platform SR6850HW4 accommodates slide rails to mount the chassis into a standard 19-inch rack. The slide rails attach to studs on the sides of the chassis using keyhole features on the slide rails. No loose hardware is needed. Intel produces two accessories common to enterprise servers:

ƒAXXRAIL3U7U, which attach to the provided mounts, or any 3U to 7U server that has mounts in these locations

ƒAXXCMA3U7U, which attaches to the rail accessory to provide a cable management arm.

3.1.3 Top Cover

The top cover is a one-piece design. It attaches to the chassis with a series of slots in the sides of the chassis that align with tabs in the top cover. To install the top cover, the tabs drop into the slots and the cover slides forward. Two captive non-knurled screws on the faceplate secure the top cover in place. A tool is required to remove or install these screws. In addition, the cover has a label on the bottom side that describes system layout, jumpers and a summary of common tasks.

3.2Power and Fans

The power bay provides space for two power supply modules/blanks and for the Power Distribution Board. It is an integral member of the chassis structure. Each power supply in the power bay is approximately 7.7-inches (W) x 14.2-inches (D) x 4.1-inches (H). The redundant AC power inputs are external to the system.

The Power Distribution Board distributes the power in two ways. First, a connector on the back edge of the board mates to the power supplies. Second, a cable routes +12V power to the SCSI Backplane Board and +3.3Vstby,+12V power and signals to the Server Board Set SE8500HW4 Mainboard. The AC power is filtered with a combination 15A power plug integrated with a filter.
