Installing a Drive
1. Remove the dummy drive, by removing the screws securing the dummy drive to
the carrier. These screws are not used to mount the actual hard drive.
2. Insert a drive into the carrier with the PCB side facing down and the connector
end toward the rear of the carrier. Align the drive in the carrier so that the screw
holes line up.
3. Secure the drive to the carrier with four M3 screws, included in the chassis
accessory box.
4. Insert the drive carrier with the disk drive into its bay, keeping the carrier oriented
so that the release button is on the right side. When the carrier reaches the rear of
the bay, the release handle retracts.
5. Push the handle in until it clicks into its locked position.

Caution
SAFETY INFORMATION
IMPORTANT: See installation instructions and safety warning before
connecting system to power supply.
http://www.supermicro.com/about/policies/safety_information.cfm
WARNING:
To reduce risk of electric shock/damage to equipment, disconnect power
from server by disconnecting all power cords from electrical outlets.
If any CPU socket empty, install protective plastic CPU cap.
WARNING:
Always be sure all power supplies for this system have the same power
output. If mixed power supplies are installed, the system will not operate.

1. Removing the Processor Force Frame
Use a Torx T20 driver to loosen the screws holding
down Force Frame in the sequence of 3-2-1. The
screws are numbered on the Force Frame next to each
screw hole.
2. Raising the Force Frame 3. Lifting the Rail Frame
5. Inserting the Carrier Frame/CPU Package 6. Lowering the Force Frame 7. Securing the Force Frame
Secure the screws in the order 1-2-3, tightening to
16.1 kgf-cm (14 lbf-in) of torque. The Force Frame
secures both the Rail Frame and CPU Package.
Caution: Tightening must be executed in proper
1-2-3 sequence to avoid causing catastrophic
damage to the socket or CPU Package.

DIMM Module Population Sequence
When installing memory modules, the DIMM slots should be populated in the following
order: DIMMA2, DIMMB2, DIMMC2, DIMMD2, DIMME2, DIMMF2, DIMMG2, DIMMH2, then
DIMMA1, DIMMB1, DIMMC1, DIMMD1, DIMME1, DIMMF1, DIMMG1, DIMMH1.
•
• Always use DDR4 DIMM modules of the same type, size and speed.
• Mixed DIMM speeds can be installed. However, all DIMMs will run at the speed of the
slowest DIMM.
• The motherboard supports an odd number of modules (1, 3, etc.). However, to achieve the
best memory performance, a balanced memory population is recommended.
