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.

SAS2-836EL Backplane User's Guide Chapter 3 Dual Port and Cascading Confi gurations Single and Dual Port Expanders Single Ports SAS2-836EL1 backplanes have a single-port expander that accesses all hard drives and supports cascading. Dual Ports SAS2-836EL2 backplanes have dual-port expanders that access all the hard drives.
SAS2-836EL Backplane User's Guide Failover The SAS2-836EL2 backplane has two expanders which allow effective failover. SAS HBA Single Host Bus Adapter In a single host bus confi guration, the SEC_J2 SEC_J1 PRI_J2 PRI_J3 R284 EC15 FANFAIL_LED_DISABLE FAN_MONITOR_DISABLE PRI_J1 C154 EC20...
SAS2-836EL Backplane User's Guide Failover with RAID Cards and Multiple HBAs The SAS-836EL backplane may be confi gured for failover with multiple HBAs using either RAID controllers or HBAs to achieve failover protection. RAID Controllers: If RAID controllers are used, then the failover is accomplished through port failover on the same RAID card.
In a cascaded confi guration, the fi rst chassis includes a motherboard and at least one host bus adapter. Other servers in this enclosed system must have a power card. This section describes the supported power card for the SAS2-836EL series backplanes.
HBAs for important information on supported confi gurations. Supported Internal HBA Cables Use the following listed cables to create connections between the internal HBA and SAS2-836EL backplane. The cables required depend on the HBA connector. Cable Name: iPass to 4-lane Part #: CBL-0117L...

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 (36-pin) at each end. It connects from the HBA to the SAS2-836EL backplane.
SAS2-836EL Backplane User's Guide Connecting an External Host Bus Adapter to the Backplane This backplane supports external host bus adapters. In this confi guration, the HBA and the backplane are in different physical chassis. This allows a JBOD confi gura- tion system to connect to another system that has an HBA.
