System Safety
2-1
Overview
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 setup and
operational within a minimal amount of time. This quick set up 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.
You will also need it placed near at least one grounded power outlet. When configured, the SC936 chassis includes two power supplies. "R" models a redundant
power supply and require two grounded outlets.
2-3
Preparing for Setup
The SC936 Chassis includes a set of rail assemblies, including mounting brackets
and mounting screws you will need to install the system into a rack. Please read
this manual in its entirety before you begin the installation procedure.
2-4
Electrical Safety Precautions
Basic electrical safety precautions should be followed to protect yourself from harm
and the SC936 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 disconnect the power from
the system.
2-1
SC936 Chassis Manual
•
•
•
•
•
•
•
•
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 motherboard, memory modules,
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.
Motherboard Battery: CAUTION - There is a danger of explosion if the on-board
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.
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.

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.
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.
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.
2-3
SC936 Chassis Manual
•
•
•
•
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.

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. Most SC936 models have two buttons
on the chassis 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.
3-1
SC936 Chassis Manual
3-2
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.
•
•
3-3
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. Therefore,
you must unplug system before servicing.
Reset: The reset button is used to reboot the system
Control Panel LEDs
The control panel located on the front of the SC936 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: Indicates power is being supplied to the system's power supply units.
This LED should normally be illuminated when the system is operating.
HDD: Indicates IDE channel activity. SAS drive, SCSI drive, and/or DVD-ROM
drive activity when flashing.
3-2
Chapter 3 System Interface
•
•
•
NIC1: Indicates network activity on GLAN1 when flashing.
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.
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.

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 which is 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 others).

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 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 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.).

Rack Mounting Instructions
This section provides information on installing the SC936 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 26" and 33.5" deep.
Identifying the Sections of the Rack Rails
The chassis package includes two rack rail assemblies : an inner fixed chassis rail
that secures directly to the server chassis and an outer fixed rack rail that secures
directly to the rack itself.
Inner Rail Extension
The SC936 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.Installing the Inner Rails
1. Place the inner rack 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 screws as illustrated.
4. Repeat steps 1-3 for the other inner rail extension.
Figure 5-1: Identifying the Sections of the Rack Rails
5-4
Chapter 5 Rack Installation
Installing the Outer Rails to the Rack
1. Attach the short bracket to the outside of the long bracket. You must align the
pins with the slides. Also, both bracket ends must face the same direction.
2. Adjust both the short and long 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 screws and
the short bracket to the rear side of the outer rail with three screws.
4. Repeat steps 1-4 for the left outer rail.
Figure 5-2: Outer Rails
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 (it may be necessary to depress the locking tabs when inserting). When
the server has been pushed completely into the rack, you should hear the
locking tabs "click" into position.
4. (Optional) Insert and tightening the thumbscrews that hold the front of the
server to the rack.
