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

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 BPN-SAS3-946LEL1 series backplane.

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

Connecting Backplane in a Server to Internal Controller and to Backplanein a JBOD
1. Power down the system and remove the power cords from the rear of thepower supplies. Open the chassis cover and access the backplanes as described in your system manual.
2. Locate connectors CN1 and CN2 on the underside of the 1st backplane.
3. Plug the cables into the 1st backplane connectors CN1 and CN2, then route
them to connectors CN1 and CN2 on the underside of the AOM-S3108MH8L-P SAS controller or AOM-S3008-L8-SB HBA in the same server as the
1st backplane, as illustrated in Figure 3-1.
4. To connect the 1st backplane connectors CN3 and CN4 to the 2nd backplaneconnectors CN1 and CN2, plug the External MiniSAS HD to External MiniSAS
HD 1m cables (CBL-SAST-0573) into the server out port and into the JBOD in
upstream port of the JBOD where the 2nd backplane is located, as illustrated
in Figure 3-1.
5. A 3rd backplane can be added using a connection from CN3 and CN4 of the
2nd backplane through its JBOD out downstream port.
6. Close the chassis cover, plug the power cords into the rear of the power supplies, and power up the system.

Connecting Backplanes in JBODs to External Controller
1. Power down the system and remove the power cords from the rear of thepower supplies. Open the chassis cover and access the backplanes as described in your system manual.
2. To connect the 1st backplane connectors CN1 and CN2 to the controller
located in a server, plug the External MiniSAS HD to External MiniSAS HD
1m cables (CBL-SAST-0573) into the JBOD in upstream port of the JBOD

Cascading Configuration, Backplane to Internal HBA
Controllers
A server configures two internal HBA cards for MPIO maximum performance.
Connecting Backplane in a Server to Internal HBAs
1. Power down the system and remove the power cords from the rear of thepower supplies. Open the chassis cover and access the backplane as described in your system manual.
2. Locate connectors CN1 and CN2 on the underside of the backplane in aserver.
3. Plug the cables into connectors CN1 and CN2, then route them to connectors
CN1 and CN2 on the underside of the AOM-S3008-L8-SB HBA located within
the same server as the backplane, as illustrated in Figure 3-3.
4. Locate connectors CN3 and CN4 on the underside of the backplane.
5. Connect the cables to CN3 and CN4, then route them to CN1 and CN2 on
the underside of the AOC-S3008L-L8E HBA in the same server, as illustrated
in Figure 3-3.
6. Close the chassis cover, plug the power cords into the rear of the power supplies, and power up the system.

Chapter 3: Cascading Configurations

Cascading Configuration, Backplane to Internal SAS
Controllers
A server configures two internal RAID controller cards with zoning utility enabled(Flexible Zoning). The 1st RAID controller card can be assigned to the first X
number of drives. The 2nd RAID controller card can be assigned to the rest of thedrives (45 - X).
Connecting Backplane in a Server to Internal RAID Controller Cards
1. Power down the system and remove the power cords from the rear of thepower supplies. Open the chassis cover and access the backplane as described in your system manual.
2. Locate connectors CN1 and CN2 on the underside of the backplane in aserver.
3. Plug the cables into connectors CN1 and CN2, then route them to connectors
CN1 and CN2 on the underside of the AOM-S3108M-H8L-P RAID controllercard located within the same server as the backplane, as illustrated in Figure
3-4.
4. Locate connectors CN3 and CN4 on the underside of the backplane.
5. Connect the cables to CN3 and CN4, then route them to CN1 and CN2 on
the underside of the AOC-S3108L-H8IR RAID controller card in the same
server, as illustrated in Figure 3-4.
6. Close the chassis cover, plug the power cords into the rear of the power supplies, and power up the system.
