1-5 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 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 first for any product problems.

Rack Installation

5-1

1 Overview

This chapter provides a quick setup checklist to install the chassis into a rack. Fol­lowing these steps in the order given should enable you to have the system installed
within a minimal amount of time.

2 Unpacking the System

You should inspect the box which the chassis was shipped in and note if it was
damaged in any way. If the chassis itself shows damage, you should file a damage
claim with the carrier who delivered it.

Decide on a suitable location for the rack unit that will hold your chassis. It should
be situated in a clean, dust-free area that is well ventilated. Avoid areas where
heat, electrical noise and electromagnetic fields are generated. The system needs
to be placed near a grounded power outlet. Be sure to read the Rack and Server
Precautions in the next section.

3 Preparing for Setup

The box your chassis was shipped in should include two sets of rail assemblies and
the mounting screws needed for installing the system into the rack. Also included
is an optional square hole to round hole converter bracket, for use in racks with
round mounting holes. Please read this section in its entirety before you begin the
installation procedure outlined in the sections that follow.

Choosing a Setup Location

• Leave enough clearance in front of the rack to enable you to open the front

door completely (~25 inches).

• Leave approximately 30 inches of clearance in the back of the rack to allow for

sufficient airflow and ease in servicing.

• This product is for installation only in a Restricted Access Location (dedicated

equipment rooms, service closets and the like).

SC846 Chassis Manual

4 Warnings and Precautions

Rack Precautions

• Ensure that the leveling jacks on the bottom of the rack are fully extended to

the floor with the full weight of the rack resting on them.

• In single rack installations, stabilizers should be attached to the rack.

• In multiple rack installations, the racks should be coupled together.

• Always make sure that the rack is stable before extending a component from

the rack.

• You should extend only one component at a time - extending two or more si-

multaneously may cause the rack to become unstable.

General Server Precautions

• Review the electrical and general safety precautions that came with the com-

ponents you are adding to your chassis.

• Determine the placement of each component in the rack before you install the

rails.

• Install the heaviest server components on the bottom of the rack first, and then

work upwards.

• Use a regulating uninterruptible power supply (UPS) to protect the server from

power surges, voltage spikes and to keep your system operating in case of a
power failure.

• Allow the hot plug hard drives and power supply modules to cool before touch-

ing them.

• Always keep the rack's front door and all panels and components on the servers

closed when not servicing to maintain proper cooling.

Chapter 5: Rack Installation

Rack Mounting Considerations

Ambient Operating Temperature

If installed in a closed or multi-unit rack assembly, the ambient operating tempera­ture of the rack environment may be greater than the ambient temperature of the
room. Therefore, consideration should be given to installing the equipment in an
environment compatible with the manufacturer’s maximum rated ambient tempera­ture (TMRA).

Reduced Airflow

Equipment should be mounted into a rack so that the amount of airflow required
for safe operation is not compromised.

Mechanical Loading

Equipment should be mounted into a rack so that a hazardous condition does
not arise due to uneven mechanical loading.

Circuit Overloading

Consideration should be given to the connection of the equipment to the
power supply circuitry and the effect that any possible overloading of circuits
might have on overcurrent protection and power supply wiring. Appropriate
consideration of equipment nameplate ratings should be used when addressing
this concern.

Reliable Ground

A reliable ground must be maintained at all times. To ensure this, the rack itself
should be grounded. Particular attention should be given to power supply connec­tions other than the direct connections to the branch circuit (i.e. the use of power
strips, etc.).

To prevent bodily injury when mounting or servicing this unit in a rack, you
must take special precautions to ensure that the system remains stable.

The following guidelines are provided to ensure your safety:

• This unit should be mounted at the bottom of the rack if it is the only unit in

the rack.

• When mounting this unit in a partially filled rack, load the rack from the bottom

to the top with the heaviest component at the bottom of the rack.

• If the rack is provided with stabilizing devices, install the stabilizers before

mounting or servicing the unit in the rack.

SC846 Chassis Manual

5-6 Rack Mounting Instructions

This section provides information on installing the chassis into a rack unit with the
rails provided. There are a variety of rack units on the market, which may mean
that the assembly procedure will differ slightly from the instructions provided. You
should also refer to the installation instructions that came with the rack unit you are
using. NOTE: This rail will fit a rack between 26.5" and 36.4" deep.

Identifying the Sections of the Rack Rails

The chassis package includes two rail assemblies in the rack mounting kit. Each
assembly consists of three sections: An inner chassis rail which secures directly to
the chassis, an outer rail that secures to the rack, and a middle rail which extends
from the outer rail. These assemblies are specifically designed for the left and right
side of the chassis.

Chapter 5: Rack Installation

Locking Tabs

Each inner rail has a locking tab. This tab locks the chassis into place when installed
and pushed fully into the rack. These tabs also lock the chassis in place when fully
extended from the rack. This prevents the server from coming completely out of
the rack when when the chassis is pulled out for servicing.

Releasing the Inner Rail

Releasing Inner Rail from the Outer Rails

1. Identify the

left and right outer rail assemblies as described on page 5-4.

2. Pull the inner rail out of the outer rail until it is fully extended as illustrated
below.

3. Press the locking tab down to release the inner rail.

4. Pull the inner rail all the way out.

• 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.

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.

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
identified 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 jumper is off the

SAS-846EL Backplane Specifications

To avoid personal injury and property damage, carefully follow all the safety steps
listed below when accessing your system or handling the components.

1 ESD Safety Guidelines

Electrotatic Discharge (ESD) can damage electronic components. To prevent damage
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.

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
identified 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 jumper is off the
pins.
