Chapter 2: System Safety  
Chapter 2  
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 config-  
ured, the SC827 chassis includes one power supply.  
2-3 Preparing for Setup  
The SC827 chassis includes a set of rail assemblies, including mounting brackets  
and 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.  
2-4 Electrical Safety Precautions  
Basic electrical safety precautions should be followed to protect yourself from harm  
and the SC827 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.  
2-1  
Download from Www.Somanuals.com. All Manuals Search And Download.  
SC827 Chassis Manual  
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 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 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.  
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.  
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 uncon-  
ventional way.

Chapter 2: System Safety  
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.  
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.

SC827 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 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  
Chassis Components  
3-1 Overview  
This chapter describes the most common components included with your chassis.  
Some components listed may not be included or compatible with your particular  
chassis model. For more information, see the installation instructions detailed later  
in this manual.  
3-2 Components  
Chassis  
The SC827 chassis includes twelve hot-swappable hard drive bays. For more  
Backplane  
Each SC827 chassis comes equipped with either a SAS-827B or SAS-827T back-  
plane. For more information regarding compatible backplanes, view the appendices  
found at the end of this manual.  
Fans  
The SC827 chassis accepts four system fans. System fans for the SC827 chassis  
are powered from the motherboards or the HDD backplane. On SC827H model  
chassis, the two fans on each side are controlled by two motherboards, so that  
when one of the motherboard nodes is removed, the second motherboard will  
continue to control both fans. In the SC827T chassis, each fan is controlled by one  
motherboard, so if a motherboard drawer is removed, the fan associated with that  
motherboard will not continue to operate.  
Mounting Rails  
The SC827 includes a set of quick-release rails, and can be placed in a rack for  
secure storage and use. To setup your rack, follow the step-by-step instructions  
included in this manual.

supply, rated at 1200 or 1400 Watts. In the unlikely event your power supply fails,  
replacement is simple and can be accomplished without tools.  
Air Shroud  
The SC827 chassis requires mylar air shrouds for each node to direct the airflow  
where cooling is needed. The air shroud will differ for different motherboards. If using  
a motherboard which is not the default in the chassis, refer to the optional parts in  
to puchase the proper air shroud.

SC827 Chassis Manual  
4-2 Control Panel Buttons  
Power: The main power button on each of the four control panels is  
used to apply or remove power from the power supply to each of the  
four systems in the chassis. Turning off system power with this but-  
ton removes the main power, but keeps standby power supplied to the  
system. Therefore, you must unplug system before servicing. The poer  
button has a built-in LED which will turn green when the power is on.  
UID: When used with a UID compatible motherboard, the UID button is used  
to turn on or off the blue light function of the LED. This is built into the front  
side of the UID button and at the rear end of each motherboard node, for those  
motherboards which support it. Once the blue light is activated, the unit can be  
easily located in very large racks and server banks.  
4-3 Control Panel LEDs  
The four control panels are located on the front handle of the SC827 chassis. Each  
control panel has two additional LEDs. These LEDs provide you with critical informa-  
tion 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.  
!
Alert: This LED is illuminated when an alert condition occurs.  
A solid red light indicates an overheat condition in the system.  
A flashing red light which flashes in one second intervals indicates a fan  
failure.  
A flashing red light which flashes in four second interfals indicates a power  
failure. When notified of an alert, 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 and air shrouds are installed. Finally, veri-  
fy that the heatsinks are installed properly. This LED will remain flashing or on

Compatible Motherboards  
Most Supermicro Twin series motherboards are compatible with the SC827 chassis.  
For the most up-to-date information on compatible motherboards and other parts,  
Hot-swappable motherboards feature different adapter cards, depending upon the  
motherboard. Adapter cards are optional and are not included with the chassis. For  
information on ordering adapter cards, see the appendix of this manual or visit the  
Permanent and Optional Standoffs  
Standoffs prevent short circuits by securing space between the motherboard and  
the chassis surface. The SC827 chassis includes permanent standoffs in locations  
used by the motherboards. These standoffs accept the rounded Phillips head screws  
included in the SC827 accessories packaging.  
Some motherboards require additional screws for heatsinks, general components  
and/or non-standard security. Optional standoffs are used for these mother-  
boards.  
To use an optional standoff, you must place a hexagon screw through the bottom  
the chassis and secure the screw with the hexagonal nut (rounded side up).  
Depending upon the configuration of the motherboard being used, it is also pos-  
sible that some of the optional standoffs which are pre-installed in the chassis, may  
need to be removed.

Chapter 5: Chassis Setup and Maintenance  
5-9 System Fans  
Four fans provide cooling for the chassis. These fans circulate air through the chas-  
sis as a means of lowering the chassis internal temperature. The SC827 system fans  
are easy to change modules. There is no need to uninstall any other parts inside  
the system when replacing fans, and no tools are required for installation.  
Optional Fan Configurations  
The SC827H model chassis is designed so that the default configuration of the  
system is for each motherboard to control two fans. Each motherboard node in  
the chassis is connected to the backplane through the adapter card, mounted in  
the motherboard node drawer. In the event that one of the motherboard drawers is  
removed, then the remaining motherboard will operate both fans.  
The SC827T model chassis has a default configuration with one fan wired directly  
to each motherboard. In the event that one of the motherboard drawers is removed,  
then the fan associated with that motherboard will not function until the drawer is  
replaced. If multiple controls are desired in the SC827T, an optional cable must be  
purchased separately to connect from the backplane to each motherboard node.  
Fan Configurations Options  
SC827T Default Configuration  
Fan A wired directly to Node A  
Fan B wired directly to Node B  
Fan C wired directly to Node C  
Fan D wired directly to Node D

5-10 Power Supply  
Depending on your chassis model, the SC827 chassis will include a 1200W or  
1400W power supply. This power supply is auto-switching capable. This enables it  
to automatically sense and operate at a 100v to 240v input voltage. An amber light  
will be illuminated on the power supply when the power is off. An illuminated green  
light indicates that the power supply is operating.  
Power Supply Replacement  
The SC827 chassis utilizes two redundant power supplies. In the unlikely event that  
the power supply unit needs to be replaced, one power supply can be removed,  
without powering down the system. Replacement units can be ordered directly from  
Supermicro (See the contact information in the Preface of this manual).

Chapter 6  
Rack Installation  
6-1 Overview  
This chapter provides a quick setup checklist to get your chassis up and running.  
Following these steps in the order given should enable you to have the system  
operational within a minimal amount of time.  
6-2 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.  
6-3 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).

6-4 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.

Chapter 6: 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.  
6-5 Rack Mounting Considerations  
Ambient Operating Temperature  
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-  
ture 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 tempera-  
ture (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 connec-  
tions other than the direct connections to the branch circuit (i.e. the use of power  
strips, etc.).

6-6 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 6: 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.

SAS-827T Safety Guidelines  
To avoid personal injury and property damage, carefully follow all the safety steps  
listed below when accessing your system or handling the components.  
C-1 ESD Safety Guidelines  
Electrostatic Discharge (ESD) can damage electronic components. To prevent dam-  
age 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.  
C-2 General Safety Guidelines  
Always disconnect power cables before installing or removing any components  
from the computer, including the SAS-827T backplane.  
Disconnect the power cable before installing or removing any cables from the  
SAS-827T backplane.  
Make sure that the SAS-827T backplane is securely and properly installed on  
the motherboard to prevent damage to the system due to power shortage.

Pins  
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

SAS-827B 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 dam-  
age 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 SAS-827B backplane.  
Disconnect the power cable before installing or removing any cables from the  
SAS-827B backplane.  
Make sure that the SAS-827B backplane is securely and properly installed on  
the motherboard to prevent damage to the system due to power shortage.
