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.
SC936 Chassis Manual • • • • • • • • 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 motherboard, memory modules, DVD-ROM and floppy drives (not necessary for hot swappable drives). When disconnecting power, you should first power down the system with the operating system and then unplug the power cords from all the power supply modules in the system.
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.
SC936 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 motherboard 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 motherboard.
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 SC936 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.
SC936 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 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 standby power supplied to the system. Therefore, you must unplug system before servicing.
Chapter 3 System Interface • • • NIC1: Indicates network activity on GLAN1 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. You should also check to make sure that the chassis covers are installed.

If necessary, remove the rear fan by pressing the fan release tab and pulling the fan from the chassis. 2.
SC936 Chassis Manual 5. The air shroud includes perforations on the bottom. These perforations can be removed if motherboard components interfere with the air shroud placement. Do not remove more perforations than necessary. 6. Install the rear fans by sliding each fan into the fan housing on the chassis. Checking the Server's Air Flow 1. Make sure there are no objects to obstruct airflow in and out of the server.
Chapter 4 Chassis Setup and Maintenance Figure 4-5: Placing the System Fan Replacing a System Fan 1. If necessary, open the chassis while the power is running to determine which fan has failed. (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. Remove the failed fan's power cord from the motherboard. 4.
SC936 Chassis Manual 4-7 Power Supply The SC936 Chassis has an auto-switching power supply. This enables it to automatically sense and operate at a 100v to 240v input voltage. An amber light illuminates on the power supply when the power is off. An illuminated green light indicates that the power supply is operating. The SC936 chassis includes a redundant power supply that can be changed without powering down the system.
Chapter 4 Chassis Setup and Maintenance Figure 4-7: Changing the Power Distributor Server chassis that are 2U or higher require a power distributor. The power distributor provides failover and power supply redundancy. In the unlikely event you must change the power distributor, do following: Changing the Power Distributor 1. Power down the server and remove the plug from the wall socket or power strip. 2.
