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 setup and operational within a minimal amount of time. This quick set up assumes that you are an experienced technician, famailiar with common concepts and terminology.
SC848 Chassis Manual 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).
Chapter 2: System Safety 2-5 • • • • • 2-6 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.
SC848 Chassis Manual • • • • 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 SC848 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.
SC848 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.
SC848 Chassis Manual 3-4 Drive Carrier LEDs Your chassis uses SAS/SATA. SAS/SATA Drives Each SAS/SATA drive carrier has two LEDs. • Blue: Solid on = Drive is present and available.
