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.
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.
Chapter 2: System Safety 2-5 • • • • • 2-6 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.
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 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 information, visit our Web site at: http://www.supermicro.com.
SC827 Chassis Manual Power Supply Each SC827 chassis model includes a high-efficiency 80 Plus Gold Level power 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.
Chapter 4: System Interface Chapter 4 System Interface 4-1 Overview There are several LEDs on the control panel and on the drive carriers to keep you constantly informed of the overall status of the system. SC827 models include four control panels on the handles of the chassis which control each of the systems. This chapter explains the meanings of all LED indicators and the appropriate response you may need to take.
SC827 Chassis Manual 4-2 • • 4-3 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 button 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.
Chapter 4: System Interface as long as the temperature is too high or a fan does not function properly. • 4-4 NIC: Indicates network activity on either LAN1 or LAN2 when flashing . Drive Carrier LEDs The SC827 chassis uses SAS/SATA drives. SAS/SATA Drives Each SAS/SATA drive carrier has two LEDs. • • Blue: Each Serial ATA drive carrier has a blue LED. When illuminated, this blue LED (on the front of the SATA drive carrier) indicates drive activity.

In addition, if you are using a front bezel, make sure the bezel's filter is replaced periodically. 2. Do not operate the server without drives or drive trays in the drive bays. Use only recommended server parts. 3. Make sure no wires or foreign objects obstruct airflow through the chassis. Pull all excess cabling out of the airflow path or use shorter cables. 4.
Chapter 5: Chassis Setup and Maintenance 5-9 System Fans Four fans provide cooling for the chassis. These fans circulate air through the chassis 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.
SC827 Chassis Manual Figure 5-18: System Fan Placement Changing a System Fan 1. If necessary, open the chassis while the power is running to determine which fan has failed. (Never run the server for an extended period of time with the chassis cover open.) 2. Remove the failed fan's power cord from the backplane. 3. Lift the fan housing up and out of the chassis. 4. Push the fan up from the bottom and out of the top of the housing. 5.
Chapter 5: Chassis Setup and Maintenance 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.
SC827 Chassis Manual Changing the Power Supply 1. Power down all four nodes and unplug the power cord. (Not necessary with redundant power supplies) 2.

Chapter 6: Rack Installation 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.
SC827 Chassis Manual ! 6-4 • Warning! ! 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.
Chapter 6: Rack Installation • 6-5 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.
SC827 Chassis Manual 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.
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. 2.
