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:
ƒ AXXRAIL3U7U, which attach to the provided mounts, or any 3U to 7U server that has
mounts in these locations
ƒ AXXCMA3U7U, 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.
3.2 Power 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 +3.3V
stby
,+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.
