Following the steps in the 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, familiar with common concepts and terminology. 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 ventilated. Avoid areas where heat, electrical noise and electromagnetic fields are generated. You will also need to place the system near at least one grounded power outlet. The SC826 chassis includes a primary and a redundant power supply, which require two grounded outlets. 3 Preparing for Setup The SC826 chassis includes a set of rail assemblies, including mounting brackets and the 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 SC826 Chassis Manual 4 Electrical Safety Precautions Basic electrical safety precautions should be followed to protect yourself from harm and the SC826 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 installing 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 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. • 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 • DVD-ROM laser: CAUTION - This chassis 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. 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 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. 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 SC826 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 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: 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. SC826 chassis models have two buttons on the 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. Figure 3-1: Chassis User Interface 3-1 SC826 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. • Reset: The reset button is used to reboot the system. • 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 stand-by power supplied to the system. Therefore, you must unplug system before servicing. 3-3 Control Panel LEDs The control panel located on the front of the SC826 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 Failure: When this LED flashes, it indicates a power failure in the power supply. 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 3-2 Chapter 3: System Interface 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. • NIC2: Indicates network activity on GLAN2 when flashing. • NIC1: Indicates network activity on GLAN1 when flashing. • • HDD: Indicates IDE channel activity. SAS/SATA drive and/or DVD-ROM drive activity when flashing. Power: Indicates power is being supplied to the system's power supply units. This LED should normally be illuminated when the system is operating. 3-3 SC826 Chassis Manual 4 Drive Carrier LEDs Your chassis uses SAS or SATA, but not both at the same time. SAS/SATA Drives Each SAS/SATA drive carrier has two LEDs. • Green or Blue: Each SAS/SATA drive carrier has a green LED. When illuminated, this green LED (on the front of the SAS/SATA drive carrier) indicates drive activity. A connection to the SAS/SATA backplane enables this LED to blink on and off when that particular drive is being accessed. • Red: The red LED indicates a SAS/SATA drive failure. If one of the SAS/SATA drives fail, you should be notified by your system management software. 3-4 Chapter 4: Chassis Setup and Maintenance Chapter 4 Chassis Setup and Maintenance 1 Overview This chapter covers the steps required to install components and perform maintenance on the chassis.

Following these steps in the order given should enable you to have the system operational within a minimal amount of time. 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. 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). 5-1 SC826 Chassis Manual ! 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. • 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. 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. 5-5 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.). 5-3 SC826 Chassis Manual 5-6 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 5-1: Identifying the Outer Rail, Middle Rail and Inner Rails (Left Rail Assembly Shown) 5-4 Chapter 5: 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. Pull the inner rail out of the outer rail until it is fully extended as illustrated below. 3. Press the locking tab down to release the inner rail. 4. Repeat steps 1-3 for the second outer rail. 1 12 13 4 1 Figure 5-2: Extending and Releasing the Inner Rail 5-5 SC826 Chassis Manual Inner Rails 14 2 14 3 Figure 5-3: Installing the Inner Rails Figure 5-4: Inner Rails Installed on the Chassis (The illustrations above are an example, the actual chassis may differ slightly) Installing The Inner Rails on the Chassis Installing the Inner Rails 1.
