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 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.
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.
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 • • • • • 2-6 General Safety Precautions Keep the area around the chassis clean and free of clutter.
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.
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.
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. • • 3-3 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.
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.
SC826 Chassis Manual 3-4 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.
Chapter 4: Chassis Setup and Maintenance Chapter 4 Chassis Setup and Maintenance 4-1 Overview This chapter covers the steps required to install components and perform maintenance on the chassis.

Use only recommended server parts. 3. Make sure no wires or foreign objects obstruct air flow through the chassis.
Chapter 4: Chassis Setup and Maintenance 4-8 System Maintenance In most cases, the chassis power supply and fans are pre-installed. If you need to install fans, continue to the System Fans section of this chapter. If the chassis will be installed into a rack, continue to the next chapter for rack installation instructions.
SC826 Chassis Manual System Fans Three heavy-duty fans provide cooling for the chassis. These fans circulate air through the chassis as a means of lowering the chassis internal temperature. Release Tab Figure 4-12: System Fan Replacing a System Fan 1. If necessary, open the chassis while the power is running to determine which fan requires changing. (Never run the server for an extended period of time with the chassis open.) 2. Turn off the power to the system and unplug the system from the outlet. 3.
Chapter 4: Chassis Setup and Maintenance Figure 4-13: Placing the System Fan 4-17
SC826 Chassis Manual Power Supply The SC826 chassis has a primary and a redundant 800 or 1200 Watt power supply. These power supplies are 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. Release Tab Figure 4-14: Removing the Power Supply Changing the Power Supply 1.
Chapter 4: Chassis Setup and Maintenance Figure 4-15: Replacing the Power Distributor Power Distributor Chassis that are 2U or more in height require a power distributor.

Chapter 5: 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.
SC826 Chassis Manual ! 5-4 • 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 5: Rack Installation • 5-5 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.
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.
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.
