Chapter 2 System Safety Chapter 2 System Safety 2-1 Overview This chapter provides safety information about the SC842 chassis. These instructions assume 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 the carrier who delivered your system.
SC842 Chassis Manual 2-4 Electrical Safety Precautions Basic electrical safety precautions should be followed to protect yourself from harm and the SC842 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 DVD-ROM laser: CAUTION - This server may have come equipped with an optional DVD-ROM drive.
SC842 Chassis Manual • Use a grounded wrist strap designed to prevent electrostatic discharge. • Keep all components and printed circuit boards (PCBs) in their antistatic bags • • • • • • until ready for use. 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.
Chapter 3 Chassis Components Chapter 3 Chassis Components 3-1 Overview This chapter describes the most common components included with your chassis. Some components listed may not be included or compatible with your particular chassis model. For more information, see the installation instructions detailed later in this manual. 3-2 Components Hard Drives and Peripheral Drives The SC842 chassis supports up to five hot-swappable 3.
SC842 Chassis Manual rated at 600 Watts. (Model SC842XTQ) In the unlikely event of a power supply failure, replacement is easily accomplished without tools. 3-3 Where to get Replacement Components Although not frequently, you may need replacement parts for your system. To ensure the highest level of professional service and technical support, we strongly recommend purchasing exclusively from our Supermicro Authorized Distributors/ System Integrators/Resellers.
Chapter 4 System Interface Chapter 4 System Interface 4-1 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. SC842 models have two buttons on the chassis 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.
SC842 Chassis Manual 4-2 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 activate 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.
Chapter 4 System Interface 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 sure that the chassis covers are installed. Finally, verify that the heatsinks are installed properly.
SC842 Chassis Manual 4-4 Drive Carrier LEDs Each hard drive carrier has two LEDs. Blue: When illuminated, this blue LED (on the front of the drive carrier) indicates drive activity. A connection to the backplane enables this LED to blink on and off when that particular drive is being accessed. Red: The red LED to indicate a drive failure. If one of the hard drives fails, replace it with a compatible enterprise-level hard drive model.
