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 the outsideof the shipping carton, and mailed prepaid or hand-carried. Shipping and handlingcharges 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 the
backplane 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.

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 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, 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 thebackplane.

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

The 4-pin connectors, designated JPW3,JPW2, JPW1, JPW6, JPW5, and JPW4, provide power to the backplane. See the table on
the right for pin definitions.

2. Upgrade Connector
The upgrade connector is used for manufacturer diagnostic purposes only.

3. - 6. SAS IN Ports (Sideband included)
The SAS ports are used to connect the SAS3
drive cables. The four SAS IN ports are designated JSM1, JSM3, JSM2, and JSM4. Eachport is also compatible with SATA drives.
However, mixing SAS3 and SATA drives is notrecommended.

7. - 10. NVMe IN Ports
The NVMe ports are used to connect the NVMe
drive cables. OCuLink cable CBL-SAST-0820
should be used to connect these ports to thecorresponding ports on add-on card AOCSLG3-4E2P. The add-on card in slot 1 of themotherboard should have its ports CN1, CN2,CN3, and CN4 connected to the backplane's
ports CN1, CN3, CN5, and CN7, respectively.
The add-on card in slot 2 of the motherboard
should have its ports CN1, CN2, CN3, andCN4 connected to CN2, CN4, CN6, and CN8,
respectively.

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 functionof the connector. Pin 1 is identified witha square solder pad on the printed circuitboard. Note: On two pin jumpers, "Closed"means the jumper is on and "Open" meansthe jumper is off the pins.
