Chapter 2: System Safety

Chapter 2

System Safety

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 set up and operational within a minimal amount of time. This quick setup assumes that you are an experienced technician, famailiar 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 venilated. Avoid areas where heat, electrical noise and eletromagnetic fields are generated.

You will also need the system placed near at least one grounded power outlet. When configured, the SC847 chassis includes one power supply. "R" models include a redundant power supply and require two grounded outlets.

3 Preparing for Setup

The SC847 chassis includes a set of rail assemblies which includes 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.


4 Electrical Safety Precautions

Basic electrical safety precautions should be followed to protect yourself from harm and the SC847 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 (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.

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

SC847 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.

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. Most SC847 models have two buttons on the chassis control panel: A reset button and a power on/off switch. This chapter explains the meanings of all LED indicators and the appropriate responses you may need to take.

Figure 3-1: Control Panel


3-2 Control Panel Buttons

There are two push-buttons located on the left handle of the chassis. These are (in order from top to bottom) a power on/off button and a reset button.

HDD: Indicates IDE channel activity. SAS/SATA drive, and/or DVD-ROM drive activity when flashing.

3-2

Reset: The reset button is used to reboot the system. 3-3 Control Panel LEDs

The control panel located on the left handle of the SC847 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: The main power button 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 standby power supplied to the system. Therefore, you must unplug system before servicing.

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

Chapter 3: System Interface

NIC1: Indicates network activity on GLAN1 when flashing.

NIC2: Indicates network activity on GLAN2 when flashing.

!

Power Failure: When this LED flashes, it indicates a failure in the redundant power supply.

Overheat/Fan Fail: When this LED flashes, it indicates a fan failure. When con- tinuously 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 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.


4 Drive Carrier LEDs

The SC847 chassis uses SAS or SATA drives.

SAS/SATA Drives

Each SAS/SATA drive carrier has two LEDs. • Blue:

Solid on = Drive is present and available. Blinking = Drive is actively being accessed. Each Serial ATA drive carrier has a blue LED. When illuminated in a solid on state, this blue 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:

Solid on = Drive failure Blinking = RAID activity When the red LED is blinking, it indicates that the system is either building,

initializing or rebuilding RAID.

SCSI Drives

This chassis does not support SCSI drives at this time.

Checking the Air Flow

1.Make sure there are no objects to obstruct airflow in and out of the server. 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 air flow through the chassis. Pull all excess cabling out of the airflow path or use shorter cables.

The control panel LEDs inform you of system status. See “Chapter 3: System Interface” for details on the LEDs and the control panel buttons.

In most cases, the chassis power supply and fans are pre-installed. If you need to install fans continue to the Systems Fan section of this chapter. If the chassis will be installed into a rack, continue to the next chapter for rack installation instructions

4-8 System Fans

Seven hot-swappable, heavy-duty fans provide cooling for the chassis. These fans circulate air through the chassis thereby lowering the chassis internal temperature.

Release Tab Airflow

Replacing a System Fan

1. 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 serverboard.

3. Press the fan release tab to lift the failed fan from the chassis and pull it

completely out of the chassis.

4. Place the new fan into the vacant space in the housing while making sure the arrows on the top of the fan (indicating airflow direction) point in the same direction as the arrows on the other fans.

5. Check that the fan is working properly before replacing the chassis cover.

4-9 Power Supply

The SC847 chassis has a 1400 Watt high-efficiency redundant 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.

Redundant power supplies are hot-swappable, and can be changed without pow- ering down the system. New units can be ordered directly from Supermicro (see contact information in the Preface).

Release Tab

Figure 4-16: Power Supply Release Tab

Changing the Power Supply:

1. If your chassis includes a redundant power supply (at least two power modules), you can leave the server running and remove only one power supply. If your server has only one power supply, you must power down the server and unplug the power cord.

2. Push the release tab (on the back of the power supply) as illustrated.

3. Pull the power supply out using the handle provided.

4. Replace the failed power module with the same model.

5. Push the new power supply module into the power bay until you hear a click.

6. Plug the AC power cord back into the module and power up the server.

Rack Installation

6-1

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.

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 similar environments).


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.

Warning! ! !

6-2

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.

6-5 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.).

6-3


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.

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. Pull the inner rail all the way out.

5. Repeat steps 1-3 for the second outer rail.

To avoid personal injury and property damage, carefully follow all the safety steps listed below when accessing your system or handling the components.

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.


• 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.


• Put the card and peripherals back into their antistatic bags when not in use.

2 General Safety Guidelines

• Always disconnect power cables before installing or removing any components from the computer, including the SAS-826A backplane.

• Disconnect the power cable before installing or removing any cables from the

SAS-826A backplane.

• Make sure that the SAS-826A backplane is securely and properly installed on the motherboard to prevent damage to the system due to power shortage.

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.

E-10 Failover The SAS-826EL2 Backplane has two expanders which allow effective failover and recovery.

Single Host Bus Adapter

In a single host bus configuration, the backplane connects to one Host Bus Adapter (HBA).

Single Host Bus Adapter Failover SAS HBA

If the expander or data path in Port A fails, the system will automatically fail over to Port B.

Dual Host Bus Adapter

In a dual host bus configuration, the backplane connects to two host bus adapters.

Dual Host Bus Adapter Failover

If the expander or data path in Port A fails, the system will automatically fail over to Port B. This maintains a full connection to all drives.

Dual HBA Configuration Cables Dual Port Cable

Assembly


E-12 Supported Cascading Configuration

Cascading allows the system to access data at a faster rate by allowing several backplanes to share resources to reduce latency time.

The first backplane in a cascaded system requires a motherboard and HBA. Other servers require a power control card, not a motherboard and HBA.

Other Considerations: • Cascading supports up to one hundred twenty two hard drives

• Use the same cables for all single port configurations

• See page E-12 if your HBA is external to your backplane.
