SAS-846EL Backplane User's Guide
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 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. supermicro.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 in­curred in shipping or from failure due to the alteration, misuse, abuse or improper maintenance of products.
During the warranty period, contact your distributor fi rst 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
Electrotatic Discharge (ESD) can damage electronic com ponents. T o prevent damage to your system, it is important to handle it very carefully . The following measures are generally suffi cient 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 backplane 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.

Setting
3 2 1
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 identifi ed 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.

3-4 Supported Cascading Confi gurations
Cascading allows the system to access data at a faster rate by allowing several backplanes to share resources to reduce latency time.
The fi rst backplane in a cascaded system requires a motherboard and HBA. Other servers require a power control card with no motherboard and no HBA. For more information, see the SC846 Chassis Manual available at www.supermicro.com.
