Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required be-

fore 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.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.

This warranty only covers normal consumer use and does not cover damages in-

curred in shipping or from failure due to the alteration, misuse, abuse or improper

maintenance of products.

Duringthewarrantyperiod,contact yourdistributor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

Electrostatic Discharge (ESD) can damage electronic com ponents. To prevent dam-

age to your system, it is important to handle it very carefully. The following measures

are generally suf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 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 SAS2-826EL series backplane.

Make sure that the backplane is properly and securely on the motherboard to •

prevent damage to the system due to power outages.

1-3 An Important Note to Users

All images and layouts shown in this user's guide are based upon the latest back-

plane revision available at the time of publishing. The card you have received may

or may not look exactly the same as the graphics shown in this manual.

1-4 Introduction to the SAS2-826EL Backplane

The SAS2-826EL backplane has been designed to utilize the most up-to-date tech-

nology available, providing your system with reliable, high-quality performance.

ThismanualreectsSAS2-826ELRevision1.01,themostcurrentreleaseavailable

at the time of publication. Always refer to the Supermicro Web site at www.supermi-

cro.comforthelatestupdates, compatiblepartsandsupportedcongurations.

1-5 Overview of the SAS2-826EL1/EL2 Backplanes

The SAS2-826EL1 and SAS2-826EL2 model backplanes are identical, except that

the SAS2-826EL2 backplane has duplicate secondary components which are not

found on the SAS2-826EL1. The SAS2-826EL2 is divided into a two sections, with

the primary components on the right side of the board and the secondary compo-

nents on the left.

To modify the operation of the backplane,

jumpers can be used to choose between

optional settings. Jumpers create shorts

3-3 Failover with RAID Cards and Multiple HBAs

TheSAS2-826ELbackplanemaybecongured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,

Linux MPIOsoftwaremustbeinstalled and correctly congured to perform

the load balancing and failover tasks.

Dual Host Bus Adapter

Ina dualhost busconguration, the

backplane connects to two host bus

adapters.

Dual Host Bus Adapter Failover

If the expander or data path in Port

A fails, the system will automatically

fail over to Port B. This maintains a

full connection to all drives.

Supported Internal HBA to Backplane Cables

Use the following listed cables to create connections between the internal HBA and

backplane. The cables required depend on the HBA connector.

Cable Name: iPass TO 4-LANE

Part #: CBL-0117 Length: 46 cm (18 inches)

Description: This cable has one SFF-8484 (32-pin) connector on one end and one

iPass (SFF-8087/Mini-SAS) connector (36-pin) at the other. This cable connects

from the HBA to the SAS2-826EL backplane.

Cable Name: SFF-8087 (Mini-SAS) TO SFF-8087 (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 (36-pin) at

each end. It connects from the HBA to the SAS2-826EL backplane.

Cascading allows the system to access data at a faster rate by allowing several

backplanes to share resources to reduce latency time.
