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 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.

1-3 An Important Note to Users
All images and layouts shown in this user's guide are based upon the latest PCB
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 SAS2-847EL Backplane
The SAS2-847EL backplane has been designed to utilize the most up-to-date technology available, providing your system with reliable, high-quality performance.
This manual refl ects SAS2-847EL1 and SAS2-847EL2 Revision 1.01, the most
current release available at the time of publication. Always refer to the Supermicro
Web site at www.supermicro.com for the latest updates, compatible parts and supported confi gurations.
The SAS2-847EL1 backplane includes a primary expander chip and primary SAS
connectors. The SAS2-847EL2 includes of both primary and secondary expander
chips, as well as primary and secondary SAS connectors. The primary and secondary expanders are redundant, so that if one should fail, the other will take over.
