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 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.
2-2 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.
2-3 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
2-4 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 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 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.
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.
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.

Rack Installation
Chapter 5: Rack Installation
5-1 Overview
This chapter provides installation instructions for installing the chassis into a rack.
Following these steps in the order given should enable you to have the system operational within a minimal amount of time.
5-2 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.
5-3 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).

5-4 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 rails.
before you install the
•
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.).

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.

Explanation of Jumpers
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 the jumper is off the pins.

F-13 Failover with RAID Cards and Multiple HBAs
The SAS2-826EL backplane may be configured for failover with multiple HBAs using either RAID controllers or HBAs to acheive failover protection.
RAID Controllers: If RAID controllers are used, then the failover is accomplished through port failover on the same RAID card.
HBAs: If multiple HBAs are used to achieve failover protection and load balancing,
Linux MPIO software must be installed and correctly configured to perform the load balancing and failover tasks.
