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.

Overview
There are several LEDs on the control panel as well as others on the drive carriers
to keep you constantly informed of the overall status of the system as well as the
activity and health of specific components. Most SC846 models have two buttons
on the chassis control panel: a reset button and a power on/off switch. This chapter
explains the meanings of all LED indicators and the appropriate responses you
may need to take.
3-1
SC846 Chassis Manual
3-2
Control Panel Buttons
There are two push-buttons located on the left handle of the chassis. These are
(in order from top to bottom) a power on/off button and a reset button.
Power: The main power button is used to apply or remove power from the power
supply to the server system. Turning off system power with this button removes
the main power but keeps standby power supplied to the system. Therefore, you
must unplug system before servicing.
Reset: The reset button is used to reboot the system.
3-3
Control Panel LEDs
The control panel located on the left handle of the SC846 chassis has five LEDs.
These LEDs provide you with critical information related to different parts of the
system. This section explains what each LED indicates when illuminated and any
corrective action you may need to take.
Informational LED:
Continuously on and blue: UID function has been activated.
Flashing red: Fan failure.
Continuously on and red: Overheat condition. This may be caused by cables
obstructing the airflow in the system or the ambient room temperature being too
warm. Check the routing of the cables and make sure all fans are present and
operating normally. You should also check to make sure that the chassis covers
are installed. Finally, verify that the heatsinks are installed properly. This LED will
remain flashing or on as long as the overheat or fan failure condition exists.

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.

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).

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 simultaneously may cause the rack to become unstable.
•
General Server Precautions
Review the electrical and general safety precautions that came with the components 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 touching 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.

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.

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 motherboard to prevent damage to the system due to power shortage.

D-12 Failover with RAID Cards and Multiple HBAs
The SAS-836EL backplane may be configured for failover with multiple HBAs using
either RAID controllers or HBAs to acheive failover protection.
RAID Controllers: If RAID controllers are used, then the failover is accomplished
through port failover on the same RAID card.
HBAs: If multiple HBAs are used to achieve failover protection and load balancing,
Linux MPIO software must be installed and correctly configured to perform
the load balancing and failover tasks.
Dual Host Bus Adapter

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
Electrostatic 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 motherboard to prevent damage to the system due to power shortage.

Placement: Internal cable
Description: Internal cascading cable. Connects the backplane to the HBA or
external port. Used in dual port environments.
E-20
Appendix E: SAS2-846EL Backplane Specifications
E-13 Supported Cascading Configurations
Cascading allows the system to access data at a faster rate by allowing several
backplanes to share resources to reduce latency time.
The first backplane in a cascaded system requires a motherboard and an HBA.
Other servers require a power control card with no motherboard and no HBA. For
more information, see the SC846 Chassis Manual available at www.supermicro.
