1-4 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 at:

http://www. supermicro.com/support/rma/

Whenever possible, repack the chassis in the original Supermicro carton, using the
original packaging material. If these are no longer available, be sure to pack the
chassis securely, using packaging material to surround the chassis 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. The Supermicro warranty can be found on our website at:

2-1 Electrical Safety Precautions

!

Basic electrical safety precautions should be followed to protect yourself from harm
and the Supermicro PDU system from damage:

Be aware of the locations of the power on/off switch on the PDU as well as the •
room's emergency power-off switch, disconnection switch or electrical outlet.
If an electrical accident occurs, you can then quickly remove power from the
system.

Do not work alone when working with high voltage components.•

Power should always be disconnected from the system when removing •
or installing main system components, such as a server system. When
disconnecting power, you should fi rst power down the operating system fi rst
and then unplug the power cords.

When working around exposed electrical circuits, another person who is •
familiar with the power-off controls should be nearby to switch off the power if
necessary.

Use only one hand when working with powered-on electrical equipment. This •
is to avoid making a complete circuit, which will cause electrical shock. Use
extreme caution when using metal tools, which can easily damage any electrical
components or circuit boards they come into contact with.

Do not use mats designed to decrease static electrical discharge as protection •
from electrical shock. Instead, use rubber mats that have been specifi cally
designed as electrical insulators.

The power supply power cords must include a grounding plug and must be •
plugged into grounded electrical outlets.

System Safety

Supermicro PDU User's Guide

2-2

This product may be connected to an power system. In all cases, make sure •
that the unit is also reliably connected to Earth (ground).

2-2 General Safety Precautions

!

Follow these rules to ensure general safety:

Keep the area around the SuperRack system clean and free of clutter.•

Place any system components and accessories that have been removed away •
from the system or on a table so that they won't accidentally be stepped on.

While working on the system, do not wear loose clothing such as neckties and •
unbuttoned shirt sleeves, which can come into contact with electrical circuits or
be pulled into a cooling fan.

Remove any jewelry or metal objects from your body, which are excellent metal •
conductors that can create short circuits and harm you if they come into contact
with printed circuit boards or areas where power is present.

After accessing the inside of the system, close the system back up and secure •
it after ensuring that all connections have been made.

Keep openings positioned vertically and not horizontally. The openings should •
not become bottom openings.

For pluggable equipment, the socket-outlet should be installed near the •
equipment and should be easily accessible.

Make sure of the power source voltage when connecting the equipment to the •
power outlet.

CAUTION:• To avoid possible SERIOUS INJURY to fi ngers from power plug
disconnection:

– Do not touch disconnected plugs while other power sources are connected.
– Be sure power is not connected BEFORE installing other power plugs.
– Disconnect all power supply cords before servicing.

Chapter 2: Safety

2-3 ESD Precautions

!

Electrostatic discharge (ESD) is generated by two objects with different electrical
charges coming into contact with each other. An electrical discharge is created to
neutralize this difference, which can damage electronic com ponents and printed
circuit boards. The following measures are generally suffi cient to neutralize this
difference before contact is made to protect your equipment from ESD:

Use a grounded wrist strap designed to prevent static discharge.•

Keep all components and printed circuit boards (PCBs) in their antistatic bags •
until ready for use.

Touch a grounded metal object before removing the board from the antistatic •
bag.

Do not let components or PCBs come into contact with your clothing, which may •
retain a charge even if you are wearing a wrist strap.

Handle a board by its edges only; do not touch its components, peripheral chips, •
memory modules or contacts.

When handling chips or modules, avoid touching their pins.•

Put the serverboard and peripherals back into their antistatic bags when not •
in use.

For grounding purposes, make sure your computer chassis provides excellent •
conductivity between the power supply, the case, the mounting fasteners and
the serverboard.

2-4 Rack Mount Precautions

!

The following rack mount precautions should be considered when installing the
Supermicro PDU system:

Elevated Operating Ambient – If installed in a closed or multi-rack assembly, •
the operating ambient temperature of the rack enviornment may be greater
than room ambient temperature. Therefore you should consider installing the
rack's equipment in an environment compatible with the maximum ambient
temperature (Tma) specifi ed by the equipment manufacturer.

Reduced Air Flow – Equipment in a rack should be installed so that the amount •
of air fl ow required for safe operation of it is not compromised.

Mechanical Loading – Mount the equipment in the rack so that a hazardous •
condition of uneven mechanical loading is not achieved.

Circuit Overloading – Consider the connection of the equipment to the supply •
circuit so that overcurrent protection and supply wiring is not overloaded. Read
and consider equipment nameplate ratings when addressing this concern.

Reliable Earthing – Reliable earthing of rack-mounted equipment should be •
maintained. Pay particular attention to supply connections other than direct
connections to the branch circuit (such as the use of power strips).
