Chapter 2: System Safety
Chapter 2
System Safety
1
Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following the steps in the order given should enable you to have your chassis set up
and operational within a minimal amount of time. This quick setup assumes that you
are an experienced technician, familiar with common concepts and terminology.
2
Warnings and Precautions
You should inspect the box the chassis was shipped in and note if it was damaged
in any way. If the chassis itself shows damage, file a damage claim with carrier
who delivered your system.
Decide on a suitable location for the rack unit that will hold that 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.
You will also need to place the system near at least one grounded power outlet.
The SC826 chassis includes a primary and a redundant power supply, which require
two grounded outlets.
3
Preparing for Setup
The SC826 chassis includes a set of rail assemblies, including mounting brackets
and the mounting screws you will need to install the systems into the rack. Please
read this manual in its entirety before you begin the installation procedure.
2-1
SC826 Chassis Manual

Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC826 from damage:
•
Be aware of the locations of the power on/off switch on the chassis 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 the serverboard, memory modules
and the DVD-ROM and floppy drives (not necessary for hot-swappable drives).
When disconnecting power, you should first power down the system with the
operating system and then unplug the power cords from all the power supply
modules in the system.
•
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 electrostatic discharge as protection from
electrical shock. Instead, use rubber mats that have been specifically designed
as electrical insulators.
•
The power supply power cord must include a grounding plug and must be
plugged into grounded electrical outlets.
•
Serverboard battery: CAUTION - There is a danger of explosion if the onboard
battery is installed upside down, which will reverse its polarities This battery
must be replaced only with the same or an equivalent type recommended by
the manufacturer. Dispose of used batteries according to the manufacturer’s
instructions.
2-2
Chapter 2: System Safety
•
DVD-ROM laser: CAUTION - This chassis may have come equipped with a
DVD-ROM drive. To prevent direct exposure to the laser beam and hazardous
radiation exposure, do not open the enclosure or use the unit in any
uncon- ventional way.
5
General Safety Precautions
•
•
Keep the area around the chassis clean and free of clutter.
Place the chassis top cover and any system components 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 to the rack unit with the retention screws after ensuring that all connections
have been made.
6
System Safety
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 components and printed
circuit boards. The following measures are generally sufficient to neutralize this
difference before contact is made to protect your equipment from ESD:
•
Do not use mats designed to decrease electrostatic discharge as protection from
electrical shock. Instead, use rubber mats that have been specifically designed
as electrical insulators.
•
•
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.
2-3
SC826 Chassis Manual
•
Touch a grounded metal object before removing any board from its 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.

Chapter 3: System Interface
Chapter 3
System Interface
3-1
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. SC826 chassis models have
two buttons on the control panel, a reset button and an on/off switch. This
chapter explains the meanings of all LED indicators and the appropriate response
you may need to take.

Control Panel Buttons
There are two push-buttons located on the front of the chassis. These are (in order
from left to right) a reset button and a power on/off button.
•
Reset: The reset button is used to reboot the system.
•
Power: The main power switch 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 stand-by power supplied to the system.
Therefore, you must unplug system before servicing.
3-3
Control Panel LEDs
The control panel located on the front of the SC826 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.
!
•
•
Power Failure: When this LED flashes, it indicates a power failure in the power
supply.
Overheat/Fan Fail: When this LED flashes it indicates a fan failure. When
continuously on (not flashing) it indicates an overheat condition, which 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

Chapter 5
Rack Installation
1
Overview
This chapter provides installation instructions for installing the chassis into a rack.
Following these steps in the order given should enable you to have the system
operational 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).

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.
5-2
Chapter 5: Rack Installation
•
Always keep the rack's front door and all panels and components on the servers
closed when not servicing to maintain proper cooling.
5-5
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.).

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.

SAS-826EL 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
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 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 SAS-826EL series backplane.
•
Make sure that the backplane is properly and securely on the motherboard to
prevent damage to the system due to power outages.

SC826 Chassis Manual
D-12 Supported Cascading Configuration
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 HBA. Other
servers require a power control card, not a motherboard and HBA. For more information, see the SC826 chassis manual.

Other Considerations:
•
Cascading supports up to one-hundred and twenty-two hard drives
•
Use the same cables for all single port configurations

Appendix F: SAS2-826EL Backplane Specifications
F-13 Failover with RAID Cards and Multiple HBAs
The SAS2-826EL 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.
