Safety Information and Technical Specifi cations

Returning Merchandise for Service

A receipt or copy of your invoice marked with the date of purchase is required be­fore 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.super­micro.com/support/rma/).

Whenever possible, repack the mobile rack in the original Supermicro carton, using
the original packaging material. If these are no longer available, be sure to pack the
mobile rack securely, using packaging material to surround the mobile rack so that
it does not shift within the carton and become damaged during shipping.

This warranty only covers normal consumer use and does not cover damages in­curred in shipping or from failure due to the alteration, misuse, abuse or improper
maintenance of products.

During the warranty period, contact your distributor fi rst for any product problems.

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 mobile rack backplane by its edges only; do not touch its compo-

•

nents, 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 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.

Explanation of Jumpers

To modify the operation of the backplane,
jumpers can be used to choose between
optional settings. Jumpers create shorts
between two pins to change the function of
the connector. Pin 1 is identifi ed with a square
solder pad on the printed circuit board.

Note: On two-pin jumpers, "Closed" means
the jumper is on and "Open" means the
