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 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.
SC847 Chassis Manual 2-4 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.
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. 2-5 • • • • • 2-6 General Safety Precautions Keep the area around the chassis clean and free of clutter.
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.
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.
SC847 Chassis Manual 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. 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.
Chapter 3: System Interface 1 NIC1: Indicates network activity on GLAN1 when flashing. 2 NIC2: Indicates network activity on GLAN2 when flashing. 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.
SC847 Chassis Manual 3-4 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.
