Preface

Returning Merchandise for Service
A receipt or copy of your invoice marked with the date of purchase is required before any warranty service will be rendered. You can obtain service by calling yourvendor for a Returned Merchandise Authorization (RMA) number. When returning
to the manufacturer, the RMA number should be prominently displayed on theoutside of the shipping carton, and mailed prepaid or hand-carried. Shipping andhandling 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.supermicro.com/support/rma/).
Whenever possible, repack the backplane in the original Supermicro box, using theoriginal packaging materials. If these are no longer available, be sure to pack thebackplane in an anti-static bag and inside the box. Make sure that there is enoughpackaging 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 incurred in shipping or from failure due to the alteration, misuse, abuse or improper
maintenance of products.
During the warranty period, contact your distributor first for any product problems.

Chapter 1Safety 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 damage to your system, it is important to handle it very carefully. The following measures
are generally sufficient 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 antistaticbag.

• Handle the backplane by its edges only; do not touch its components, peripheralchips, 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 thebackplane.

• Make sure that the backplane is securely and properly installed on the motherboard to prevent damage to the system due to power shortage.

#2. Backplane to Front Panel Header
This connector is designated JF2. It connects the backplane to the front LED panelson the chassis.

#3. I2C Connector
This connector, designated J25, is used tomonitor HDD activity and status. It is onlyrequired when specified by a system manual.
See the table on the right for pin definitions.

#4. Mini-SAS HD Connectors
Connect a SAS/SATA drive cable to these
ports when configuring the SAS/SATAdrives. The ports are designated JSM1,for drives at SAS#0-3, JSM2, for drives at
SAS#4-7, and JSM3, for drives at SAS#811 (see section 2-4 for drive locations). The
ports are also compatible with SATA drives.
However, mixing SAS and SATA drives inthe same enclosure is not recommended.

should be used to connect these ports tothe corresponding ports on motherboard
X11DPU-V-P.

#6. Motherboard to Backplane Connector
This 20-pin connector, designated JF1, connects the motherboard to the backplane on
the chassis using a flat ribbon cable.

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 functionof the connector. Pin 1 is identified witha square solder pad on the printed circuitboard.
