Preface
Returning Merchandise for Service
A receipt or copy of your invoice marked with the date of purchase is required be-
fore any warranty service will be rendered. You can obtain service by calling your
vendor for a Returned Merchandise Authorization (RMA) number. When returning
to the manufacturer, the RMA number should be prominently displayed on the
outside of the shipping carton, and mailed prepaid or hand-carried. Shipping and
handling charges will be applied for all orders that must be mailed when service
is complete.
For faster service, RMA authorizations may be requested online (http://www.super-
micro.com/support/rma/).
Whenever possible, repack the backplane in the original Supermicro box, using the
original packaging materials. If these are no longer available, be sure to pack the
backplane in an anti-static bag and inside the box. Make sure that there is enough
packaging material surrounding the backplane so that it does not become damaged
during shipping.
This warranty only covers normal consumer use and does not cover damages in-
curred in shipping or from failure due to the alteration, misuse, abuse or improper
maintenance of products.

Chapter 1: Safety Guidelines
Chapter 1
Safety Guidelines
To avoid personal injury and property damage, carefully follow all the safety steps
listed below when accessing your system or handling the components.
1-1 ESD Safety Guidelines
Electrostatic Discharge (ESD) can damage electronic components. To prevent dam-
age to your system, it is important to handle it very carefully. The following measures
are generally sucient to protect your equipment from ESD.
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing a component from the antistatic
bag.
• Handle the backplane by its edges only; do not touch its components, peripheral
chips, memory modules, or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the card and peripherals back into their antistatic bags when not in use.
1-2 General Safety Guidelines
• Always disconnect power cables before installing or removing any components
from the computer, including the backplane.
• Disconnect the power cable before installing or removing any cables from the
backplane.
• Make sure that the backplane is securely and properly installed on the mother-
board to prevent damage to the system due to power shortage.

#1. Backplane Main Power Connector
The 4-pin connector, designated JPW1,
provides power to the backplane. See the
tableontherightforpindenitions.
2-2 Front Connector Pin Denitions
#3. - 4. NVMe Connectors
The NVMe ports are used to connect
the NVMe drive cables. OCuLink cables
should be used to connect these ports to
the corresponding ports on motherboard
X11DPFR-SN. The motherboard should
have its ports JNVME1 and JNVME2 con-
nected to the backplane's ports CN0 and
CN1, respectively.
#2. SAS Mini HD Connector
The SAS port is used to connect the SAS3
drive cables. The port is designated JSM0
for drives at SAS #0-#1 (see section 2-4
for SAS drive locations). The port is also
compatible with SATA drives. However,
mixing SAS3 and SATA drives in the same
enclosure is not recommended.
#5. CPLD Chip
The CPLD is an enclosure management
chip that supports the SGPIO and LED
management.

Figure 2-2. Front Jumpers
Explanation of Jumpers
To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function
of the connector. Pin 1 is identied with
a square solder pad on the printed circuit
board.
Note: On two pin jumpers, "Closed" means
the jumper is on and "Open" means the
