Chapter 2: System Safety
Chapter 2
System Safety
2-1Overview
This chapter provides a quick setup checklist to get your chassis up and running.
Following the steps in 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, famailiar with common concepts and terminology.
2-2 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 venilated. Avoid areas where heat,
electrical noise and eletromagnetic fields are generated.
The chassis must be placed near at least one grounded power outlet. When configured, the SC933 chassis includes three redundant power supplies and requires
three grounded outlets.
2-3 Preparing for Setup
The SC933 chassis includes a set of rail assemblies, including mounting brackets
and mounting screws you will need to install the system into the rack. Please read
this manual in its entirety before beginning the installation procedure.
2-1
SC933 Chassis Manual
2-4 Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC933 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 in-
stalling main system components, such as the motherboard, 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 fa-
miliar 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.
•Motherboard 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 server 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 unconventional way.
2-5 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 re-
moved 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.
2-6 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
SC933 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 motherboard 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 motherboard.

There are three push-buttons located on the front of the chassis. These are, in order
from top to bottom, a power on/off button, reset button and a mute button.
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 standby power supplied to the system. It is necessary to unplug
the system before servicing.
Reset: The reset button is used to reboot the system.
Mute
Mute: The mute button allows the system alarm to be silenced quickly.
3-3 Control Panel LEDs
The control panel located on the front of the SC933 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.
3-2
Chapter 3: System Interface
Power: Indicates power is being supplied to the system's power supply units. This
LED should normally be illuminated when the system is operating.
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 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 condition exists.
NIC1: Indicates network activity on GLAN1 when flashing.
HDD: Indicates IDE channel activity in the SAS drive, SCSI drive, and/or DVD-ROM
drive activity when flashing.
!
Power Fail: Indicates a power failure to the system's power supply units.

SC933 Chassis Manual
3-4 Drive Carrier LEDs
Your chassis uses SAS or SCSI drives, but not both.
SAS Drives
Each SAS drive carrier has two LEDs.
•Green: Each SAS drive carrier has a green LED. When illuminated, this green
LED (on the front of the SAS drive carrier) indicates drive activity. A connection
to the SAS backplane enables this LED to blink on and off when that particular
drive is being accessed.
•Red: The red LED indicates a SAS drive failure. If one of the SAS drives fail,
you should be notified by your system management software.
SCSI Drives
Each SCSI drive carrier has two LEDs.
•Green: When illuminated, the green LED on the front of the SCSI drive carrier
indicates drive activity. A connection to the SCSI SCA backplane enables this
LED to blink on and off when that particular drive is being accessed. •Red: The SAF-TE compliant backplane activates the red LED to indicate a drive
failure. If one of the SCSI drives fail, you should be notified by your system
management software.
If your system supports more drives than are currently being utilized, the LEDs
which are designated for unused drives will remain unlit.

Chapter 5: Rack Installation
Chapter 5
Rack Installation
5-1Overview
This chapter provides instructions for installing your chassis into a rack. Following
these steps in the order given should enable you to have the chassis installed within
a minimum amount of time.
5-2 Unpacking the System
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 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. You will also need
it placed near a grounded power outlet. Be sure to read the Rack and Server Precautions in the next section.
5-3 Preparing for Setup
The box your chassis was shipped in should include two sets of rail assemblies,
two rail mounting brackets and the mounting screws you will need to install the
system into the rack. 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.
5-1
SC933 Chassis Manual
•This product is for installation only in a Restricted Access Location (dedicated
equipment rooms, service closets and similar environments).
!
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 a single rack installation, stabilizers should be attached to the rack.
•In multiple rack installations, the racks should be coupled together.
•Always make sure 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 up.
•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-swappable 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.
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.).
5-3
SC933 Chassis Manual
5-4 Rack Mounting Instructions
This section provides information on installing the SC933 chassis into a rack unit
with the rails provided. There are a variety of rack units on the market, which may
mean the assembly procedure will differ slightly. 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 28" and 33.67" deep.
Identifying the Sections of the Rack Rails
The chassis package includes two rail assemblies, a fixed inner rail that secures
directly to the chassis and an outer rail that secures directly to the rack itself.
Figure 5-1: Identifying the Inner Rail Extensions
Inner Rail Extension
The SC933 chassis includes a set of inner rails in two sections: inner rails and inner
rail extensions. The inner rails are preattached and do not interfere with normal use
of the chassis if you decide not to use a server rack. Attach the inner rail extension
to stabilize the chassis within the rack.

Figure 5-2: Installing the Inner Rails
Installing the Inner Rail Extensions
1. Place the inner rail extensions on the side of the chassis aligning the hooks
of the chassis with the rail extension holes. Make sure the extension faces
"outward" just like the pre-attached inner rail.
2. Slide the extension toward the front of the chassis.
3. Secure the chassis with one screw.
4. Repeat steps 1-3 for the other inner rail extension.
5-5
SC933 Chassis Manual
Front Side
Figure 5-3: Assembling the Outer Rails
Installing the Outer Rails to the Rack
1. Attach the shorter outer rail bracket to the outside of the longer outer rail
bracket. You must align the pins with the slides. Also, both bracket ends must
face the same direction.
2. Adjust both the shorter and longer brackets to the proper distance so that the
rail fits snugly into the rack.
3. Secure the long bracket to the front side of the outer rail with two M5 screws
and the short bracket to the rear side of the outer rail with three M5 screws.
4. Repeat steps 1-3 for the remaining outer rail.

Figure 5-5: Installing the Chassis
Installing the Chassis into a Rack
1. Confirm that chassis inner rails and outer rails are installed on the rack.
2. Line chassis rails with the front of the rack rails..
3. Slide the chassis rails into the rack rails, keeping the pressure even on both
sides (you may have to depress the locking tabs when inserting). When the
server has been pushed completely into the rack, the locking tabs will click
into the locked position.
4. (Optional) Insert and tightening the thumbscrews that hold the front of the
server to the rack.

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.

C-11 Failover with RAID Cards and Multiple HBAs
The SAS-933EL 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.

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, but not a motherboard and HBA together.

SATA-933 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.
D-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.
D-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.

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.
