SC837J Chassis Manual Chapter 2 System Safety 2-1 Overview This chapter provides a quick setup 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. 2-2 Warnings and Precautions You should inspect the box the chassis was shipped in and note if it was damaged in any way.
SC837J Chassis Manual 2-4 Electrical Safety Precautions Basic electrical safety precautions should be followed to protect yourself from harm and the SC837J 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.
SC837J Chassis Manual • 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.
SC837J 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.
SC837J Chassis Manual 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. SC837J 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.
SC837J 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.
SC837J Chassis Manual 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.
SC837J 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. 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.
SC837J Chassis Manual Chapter 4 Chassis Setup and Maintenance 4-1 Overview This chapter covers the steps required to install components and perform maintenance on the chassis. The only tool you will need to install components and perform maintenance is a Phillips screwdriver. Print this chapter to use as a reference while setting up your chassis. ! ! Review the warnings and precautions listed in the manual before setting up or servicing this chassis.

SC837J Chassis Manual 4-7 Power Supply The SC837J chassis has a 1620 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 powering down the system.
