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.

Chapter 2: Hardware Information

2.3 Central Processing Unit (CPU)

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

• 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
Socket 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.

2.3.1 Installing the CPU and heatsink

To install the CPU and heatsink:

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

2. Remove the air ducts. For more information, see the section

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

8. 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

16.1±1.2 kgf-cm (14.0±1.0 lbf-in) is
recommended.

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

The heatsink screws are T20 models.
A torque value of 16.1±1.2 kgf-cm
(14.0±1.0 lbf-in) is recommended.

10. Reinstall the air ducts to complete the
CPU and heatsink installation. For more
information, refer to section

You may install 16GB, 32GB, and 64GB RDIMMs into the DIMM sockets. If you are not sure
on which slots to install the DIMMS, you can use the recommended memory configuration in
this section for reference.

• 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.)

2.4.3 Installing a DIMM on a single clip DIMM socket

Ensure to unplug the power supply before adding or removing DIMMs or other system
components. Failure to do so may cause severe damage to both the motherboard and the
components.

1. Unlock a DIMM socket by pressing the
retaining clip outward.

2. Align a DIMM on the socket such that
the notch on the DIMM matches the
DIMM slot key on the socket.

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
clips snaps back into place.

Ensure that the DIMM is sitting firmly on

the DIMM slot.

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

3. 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.

2.5 Storage devices

The system supports twenty-four (24) 2.5” hot-swap SATA/SAS/NVMe storage devices (up
to 8 x NVMe/SATA/SAS + 16 x SATA/SAS). The storage device installed on the storage
device tray connects to the motherboard SATA/SAS/NVMe ports via the SATA/SAS/NVMe
backplane.

To install a 2.5” hot-swap SATA/SAS/NVMe storage device:

1. Press the spring lock then
pull the tray lever outward to
release the storage device
tray. The storage device tray
ejects slightly after you pull
out the lever.

2. Firmly hold the tray lever and
pull the storage device tray
out of the bay.

3. Prepare the 2.5” storage
device and the bundled set
of screws.

4. Place the 2.5” storage device
into the storage device
tray then secure it with four
screws.

5. Push the storage device tray
and storage device assembly
all the way into the depth of
the bay until the tray lever
and spring lock clicks and
secures the storage device
tray in place.

• When installed, the SATA/SAS/NVMe connector on the storage device connects to the
SATA/SAS/NVMe interface on the backplane.

• The storage device tray is correctly placed when its front edge aligns with the bay
edge.

6. Repeat steps 1 to 5 to install the other SATA/SAS/NVMe storage devices.
