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.
Duringthewarrantyperiod,contact yourdistributorrstforany productproblems.

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 sufcient 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.

1-5 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.
