For faster service, RMA authorizations may be requested online (http://www.super- micro.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.
General Safety Guidelines • Always disconnect power cables before installing or removing any components from the computer, including the BPN-SAS3-846EL series backplane. • Make sure that the backplane is properly and securely on the motherboard to prevent damage to the system due to power outages.
This manual reflects BPN-SAS3-846EL Revision 1.01, the most current release available at the time of publication. Always refer to the Supermicro website at www. supermicro.com for the latest updates, compatible parts and supported configura- tions.

Chapter 3 Dual Port and Cascading Configurations Chapter 3 Dual Port and Cascading Configurations Single and Dual Port Expanders SAS primary connectors J49 to J50 and secondary connectors J51 to J52 are bidirectional and can be treated as input or output. Single Ports BPN-SAS3-846EL1 backplanes have a single port expander that accesses all of the drives and supports cascading.
BPN-SAS3-846EL1/EL2 Backplane User's Guide Failover The BPN-SAS3-846EL2 model backplane has two expanders which enable effec- tive failover and recovery. Single Host Bus Adapter In a single host bus configuration, the backplane connects to one host bus adapter. SAS HBA MH14 MH15 Q866 EXP I2C4...
Chapter 3 Dual Port and Cascading Configurations Failover with RAID Cards and Multiple HBAs The BPN-SAS3-846EL 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.

Length: 35 cm (13 inches) Part #: CBL-SAST-0593 Length: 60 cm (23 inches) Part #: CBL-SAST-0531 Length: 80 cm (31 inches) Description: This cable has a Mini-SAS HD (SFF-8643) connector at both ends. It connects from the SAS3 HBA to the BPN-SAS3-846EL model backplane.
BPN-SAS3-846EL1/EL2 Backplane User's Guide Connecting an External HBA to the Backplane This backplane supports external host bus adapters. In this configuration, the HBA and the backplane are in different physical chassis. This allows a JBOD (Just a Bunch Of Drives) configuration from an existing system. Single External Host Bus Adapter MH14 Q866...
Chapter 3 Dual Port and Cascading Configurations Connecting Multiple Backplanes in a Single Channel Environment This section describes the cables used when cascading from a single HBA.
