BPN-SAS2-846EL Backplane Manual
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 first for any product problems.

Guidelines
Chapter 1 Guidelines
This chapter offers guidelines for personal and equipment safety, and notes about the BPN-SAS2-846EL version documented in this manual.
1-1 ESD Safety Guidelines Electrostatic Discharge (ESD) can damage electronic com ponents. 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 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 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 the backplane.
• Make
sure that the backplane is securely and properly installed on the motherboard to prevent damage to the system due to power shortage.

Figure 2-2. Rear Jumper and LED Locations
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 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.

* Early versions of Supermicro SAS2 backplanes come equipped with a buzzer. New versions of these backplanes no longer support a buzzer. We recommend using the LSI MegaRAID Storage Manager or a similar management application to trigger an email alert instead. The buzzer alarm is triggered by one of the following conditions:
• Hard drive failure. • Fan failure. • System temperature over 45º Celsius.

Chapter 3
Dual Port and Cascading Configurations
3-3 Failover with RAID Cards and Multiple HBAs The SAS2-846EL backplane may be configured for failover with multiple HBAs using either RAID controllers or HBAs to acheive failover protection. RAID Controllers: If RAID controllers are used, then the failover is accomplished through port failover on the same RAID card. HBAs: If multiple HBAs are used to achieve failover protection and load balancing, MPIO software must be installed and correctly configured to perform the load balancing and failover tasks.

Figure 3-6: Connecting an Internal HBA to the Backplane IMPORTANT: See Section 3-3 of this manual, Failover with RAID Cards and Multiple HBAs for important information on supported configurations.
Supported Internal HBA Cables Use the following listed cables to create connections between the internal HBA and SAS2-846EL backplane. The cables required depend on the HBA connector. Cable Name: iPass (Mini-SAS) to iPass (Mini-SAS) Part #: CBL-0108L-02
Length: 39 cm (15 inches)
Part #: CBL-0109L-02
Length: 22 cm (9 inches)
Part #: CBL-0110L-02
Length: 18 cm (7 inches)
Description: This cable has an iPass (SFF-8087/Mini-SAS) connector with 36 pins at each end. It connects from the HBA to the SAS2-846EL backplane.

Chapter 3
Dual Port and Cascading Configurations
3-5 Supported Cascading Configurations Cascading allows the system to access data at a faster rate by allowing several backplanes to share resources to reduce latency time. The first backplane in a cascaded system requires a motherboard and an HBA. Other servers require a power control card with no motherboard and no HBA.
