Following the steps in order given should enable you to have your chassis setup and operational within a minimal amount of time. These instructions assume that you are an experienced technician, familiar 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 the carrier who delivered your system. Decide on a suitable location for the rack unit that will hold the 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 at least two grounded power outlets. The SC836 chassis includes two redundant power supplies which require two grounded outlets. 2-3 Preparing for Setup The SC836 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. 2-1 SC836 Chassis Manual 2-4 Electrical Safety Precautions Basic electrical safety precautions should be followed to protect yourself from harm and the SC836 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 serverboard, memory modules and the DVD-ROM (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. 2-2 Chapter 2: System Safety •Please handle used batteries carefully. Do not damage the battery in any way; a damaged battery may release hazardous materials into the environment. Do not discard a used battery in the garbage or a public landfill. Please comply with the regulations set up by your local hazardous waste management agency to dispose of your used battery properly. •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. 2-3 SC836 Chassis Manual •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. •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. 2-4 Chapter 3: Chassis Components Chapter 3 Chassis Components 3-1 Overview This chapter describes the most common components included with your chassis.

Following these steps in the order given should enable you to have the system operational within a minimal amount of time. 7-2 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. 7-3 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). 7-1 SC836 Chassis Manual ! Warning! ! 7-4 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 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. 7-2 Chapter 7: 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. 7-5 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.). 7-3 SC836 Chassis Manual 7-6 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. Rail Assembly (Shown with Rails Retracted) Outer Rail Middle Rail Locking Tab This Side Faces Outward Inner Rail Figure 7-1: Identifying the Outer Rail, Middle Rail and Inner Rails (Left Rail Assembly Shown) 7-4 Chapter 7: 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.

F-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 card 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. F-1 SC836 Chassis Manual F-2 General Safety Guidelines •Always disconnect power cables before installing or removing any components from the computer. •Disconnect the power cable before installing or removing any cables from the card. •Make sure that the card is securely and properly installed on the motherboard to prevent damage to the system due to power shortage. F-3 An Important Note to Users •All images and layouts shown in this user's guide are based upon the latest PCB Revision available at the time of publishing. The card you have received may or may not look exactly the same as the graphics shown in this manual.

Fan Connectors Fan Connectors The 3-pin connectors, designated Fan1 and Fan2, provide power to the fans. Pin# Definition Since the system will use the power card instead of a motherboard, two fans provide sufficient cooling for the server. 1 Ground 2 +12V 3 Tachometer #2. Main Power Connector The 12-pin connector provides power to the card to be distributed to the chassis components. #3. Power Fault Connector (MCU Power On Switch) Power Fault Connector (MCU Power On Switch) Pin# Definition In normal operating mode, power is governed by the MCU (Micro Controller Unit). As a sercurity measure, the switch must be depressed for at least four seconds to power down the system. 1 Power Fault #1 2 Power Fault #2 3 Power Fault #3 4 Reserved In the case of an unexpeceted loss of power, the MCU will return the system to the power state it was in at the time when power was lost. #4. LED and Switch Connector The LED Header and Switch Connector, designated JF1, is cabled directly to the front panel. This allows the front panel to display system status.
