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 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.

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, 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 BPN-SAS3-846EL1-N8 series backplane.

• Make sure that the backplane is properly and securely on the motherboard toprevent damage to the system due to power outages.

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 tochange the function of the connector.
Pin 1 is identified 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 jumper is off the pins.

Expander Chip Side Component Definitions#1. CPLD Upgrade Port
The CPLD programming port, designated J29,
is used only by the manufacturer to upgrade
the CPLD.

#2. NVMe Connectors
The NVMe ports, designated NVMe#0-7, arefor NVMe drives at SAS#16-23 (see section
2-1 for drive locations) and used to connect
the NVMe drive cables. To configure the first
four NVMe drives, two CBL-SAST-0848 OCuLink cables should be used to connect ports
NVMe#0-1 and two CBL-SAST-0819 OCuLink cables should be used to connect ports
NVMe#2-3 to an AOC-SLG3-4E4T, on port 2 of
RSC-S4-A6688 on motherboard X11QPH+. To
configure the remaining four NVMe drives, fourCBL-SAST-0819 OCuLink cables should beused to connect ports NVMe#4-7 to a second
AOC-SLG3-4E4T, on port 4 of RSC-S4-A6688
on motherboard X11QPH+.

#3. CPLD Chip
The CPLD is an enclosure management chipthat supports the SGPIO and LED management.

2-8Chapter 2: Connectors and LEDs
#4. MiniSAS HD Integrated Connector
The SAS port is used to connect the SAS orSATA drive cable CBL-SAST-0531 to an AOCS3108L-H8IR HBA card installed on RSC-S4RA66888 on motherboard X11QPH+. The port isdesignated JSM50, for SAS3 or SATA3 drives
at SAS#0-23 (see section 2-1 for drive locations). The port is also compatible with SATAdrives. However, mixing SAS and SATA drives
in the same enclosure is not recommended.

#5. Expander Programming Port
The primary UART connector is designated J52
and is for the manufacturer's use only.

#6. Expander Chip
This chip allows connectivity to the components on the backplane.

#7. Backplane Main Power Connectors
The 4-pin connectors, designated PWR1,PWR2, PWR3, PWR4, PWR5, and PWR6,
provide power to the backplane. See the tableon the right for pin definitions.
