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, 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 add a device.

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

Operation Safety

•Any mechanical operation on this server must be conducted by certified or experienced engineers.

•Before operating the server, carefully read all the manuals included with the server package.

•Before using the server, ensure all cables are correctly connected and the power cables are not damaged. If any damage is detected, contact your dealer as soon as possible.

•To avoid short circuits, keep paper clips, screws, and staples away from connectors, slots, sockets and circuitry.

•Avoid dust, humidity, and temperature extremes. Place the server on a stable surface.

This product is equipped with a three-wire power cable and plug for the user’s safety. Use the power cable with a properly grounded electrical outlet to avoid electrical shock.

Heavy System

CAUTION! This server system is heavy. Ask for assistance when moving or carrying the system.

The motherboard comes with a surface mount Socket SP3 socket designed for the AMD EPYC™ 7002 Series Family processors.

•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 InSocket SP3

•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.

2.2.1Installing the CPU and heatsink

1.Remove the rear chassis cover. For more information, see the section Chassis cover.

2.Remove the air duct. For more information, see the section Air Duct.

3.Locate the CPU socket on the motherboard.

4.Loosen each screw one by one in the sequence shown on the socket to open the load plate.

5.Slightly lift open the rail frame.

7.Slide the carrier frame with CPU into the rail frame, then remove the PnP cap.

The carrier frame with CPU fits in only one correct orientation. DO NOT force the carrier frame with CPU into the rail frame.

9. Close the load plate just enough to let it sit on top of the CPU, then secure each screw one by one in the sequence shown on the socket to completely secure the load plate.

The load plate screws are T20 models. A torque value of 14+/-1.0 inch-lbf is recommended.

10.Twist each of the four screws with a screwdriver in the order shown in the illustration just enough to attach the heatsink to the motherboard. When the four screws are attached, tighten them one by one in a the same diagonal sequence to completely secure the heatsink.

The heatsink screws are T20 models. A torque value of 14+/-1.0 inch-lbf is recommended.

11.Reinstall the air duct. For more information, see the section Air Duct.

2.3System memory

2.3.1Overview

The motherboard comes with eight (8) Double Data Rate 4 (DDR4) Dual Inline Memory Modules (DIMM) sockets.

The figure illustrates the location of the DDR4 DIMM sockets:

2.3.2Memory Configurations

You may install 16 GB, 32 GB, 64 GB, 128 GB, 256 GB DDR4 RDIMMs into the DIMM sockets using the memory configurations in this section.

• Refer to ASUS Server AVL for the updated list of compatible DIMMs.

• Always install DIMMs with the same CAS latency. For optimum compatibility, it is recommended that you obtain memory modules from the same vendor.

• Start installing the DIMMs into the second slots (such as DIMM_A2 , DIMM_B2, etc.)

2.3.3Installing a DIMM on a single clip DIMM socket

1.	Press the retaining clip outward to unlock DIMM notch
	a DIMM socket.
2.	Align a DIMM on the socket such that the
	notch on the DIMM matches the DIMM
	slot key on the socket.
	DIMM slot key	Unlocked retaining clip
	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 on both 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 damage to the DIMM notch.

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

•Refer to www.asus.com for vendor lists of the memory modules.

Removing a DIMM from a single clip DIMM socket

1.Press the retaining clip outward to unlock the DIMM.

2. Remove the DIMM from the socket.

Support the DIMM lightly with your fingers when pressing the retaining clips. The DIMM might get damaged when it flips out with extra force.
