Safety Information and Technical Speciﬁcations

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.

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.

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 ﬁrst 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 components. To prevent dam-

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

are generally sufﬁcient 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.
