Safety information

Electrical Safety

•Before installing or removing signal cables, ensure that the power cables for the system unit and all attached devices are unplugged.

•To prevent electrical shock hazard, disconnect the power cable from the electrical outlet before relocating the system.

•When adding or removing any additional devices to or from the system, contact a qualified service technician or your dealer. Ensure that the power cables for the devices are unplugged before the signal cables are connected. If possible, disconnect all power cables from the existing system before you service.

•If the power supply is broken, do not try to fix it by yourself. Contact a qualified service technician or your dealer.

Operation Safety

•Servicing of this product or units is to be performed by trained service personnel only.

Hardware Setup

2

This chapter lists the hardware setup procedures that you have to perform when installing system components. It includes description of the jumpers and connectors on the motherboard.

2.1Chassis cover

2.1.1Removing the side covers

•Ensure that you unplug the power cord before removing the side cover.

•Take extra care when removing the side cover. Keep your fingers from components inside the chassis that can cause injury, such as the CPU fan, rear fan, and other sharp-edged parts.

•The images of the system shown in this section are for reference purposes only and may not exactly match the model you purchase.

1. Remove the two (2) screws from the rear of the side cover, then set them aside.

2. Lift the side cover to remove it.

Be careful not to apply pressure to the air vent on the side cover to avoid damages to the system.

3.Repeat steps 1 and 2 to remove the other side cover.

2-2	Chapter 2: Hardware Setup

2.1.2Replacing the side covers

1. Align and insert the front of the side cover to the front of the chassis (A), then replace the side cover onto the chassis (B).

2. Replace the two (2) removed previously to secure the side cover to the chassis.

3.Repeat steps 1 and 2 to replace the other side cover.

ASUS E900 G4

2-3

2.2CPU installation

The motherboard comes with a surface mount LGA 3647 socket designed for the Intel® Xeon® Skylake-SP product family series processors.

Ensure that you install the correct CPU designed for LGA3647 socket only. DO NOT install a CPU designed for other sockets on the LGA3647 socket.

•Ensure that all power cables are unplugged before installing the CPU.

•Ensure that you install the correct CPU designed for LGA3647 socket only.

•Upon purchase of the motherboard, ensure that the PnP cap is on the socket and the socket contacts are not bent. Contact your retailer immediately if the PnP cap is missing, or if you see any damage to the PnP cap/socket contacts/motherboard components. ASUS will shoulder the cost of repair only if the damage is shipment/ transit-related.

•Keep the cap after installing the motherboard. ASUS will process Return Merchandise Authorization (RMA) requests only if the motherboard comes with the cap on the LGA3647 socket.

•The product warranty does not cover damage to the socket contacts resulting from incorrect CPU installation/removal, or misplacement/loss/incorrect removal of the PnP cap.

The CPU is purchased separately.

2-4	Chapter 2: Hardware Setup

Triangle mark

Apply the Thermal Interface Material to the CPU heatsink and CPU before you install the heatsink and fan, if necessary.

The CPU and heatsink assembly fits in only one correct orientation. DO NOT force the CPU and heatsink assembly into the socket to prevent damaging the CPU pins on the socket.

The heatsink screws are T30 models. A torque value of 12 inch-lbf is recommended.

ASUS E900 G4

2-5

2.3System memory

The motherboard comes with four DDR 4 (Double Data Rate 4) Dual Inline Memory Modules (DIMM) slots.

A DDR4 module is notched differently from a DDR, DDR2 or DDR3 module. DO NOT install a DDR, DDR2 or DDR3 memory module to the DDR4 slot.

Memory configurations

You may install 4 GB, 8 GB, 16 GB, and 32 GB RDIMMs; and 32 GB, and 64 GB LRDIMMs into the DIMM sockets.

•For system stability, use a more efficient memory cooling system to support a full memory load (12 DIMMs) or overclocking condition.

•Always install the DIMMS with the same CAS Latency. For an optimum compatibility, we recommend that you install memory modules of the same version or data code

(D/C) from the same vendor. Check with the vendor to get the correct memory modules.

•The DIMMs are purchased separately.

•Visit the ASUS website for the latest QVL.

A DIMM is keyed with a notch so that it fits in only one direction. DO NOT force a DIMM into a socket in the wrong direction to avoid damaging the DIMM.

3.Hold the DIMM by both of its ends

then insert the DIMM vertically into the socket. Apply force to both ends of the DIMM simultaneously until the retaining clip snaps back into place and the DIMM cannot be pushed in any further to ensure proper sitting of the DIMM.

Locked Retaining Clip

Always insert the DIMM into the socket vertically to prevent DIMM notch damage.

•To install two or more DIMMs, refer to the user guide bundled in the motherboard

package.

•Refer to the ASUS website for qualified vendor lists of the memory modules.
