SC745 Chassis Manual Notes 1-4
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 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.
SC745 Chassis Manual 2-4 Electrical Safety Precautions Basic electrical safety precautions should be followed to protect yourself from harm and the SC745 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 • 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 a DVD-ROM drive.
SC745 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 Chassis Chassis may include the following three options: • Eight hot-swappable 3.
SC745 Chassis Manual Fans The SC745 chassis accepts three system fans and two rear exhaust fans. System fans for SC745 chassis are powered from the serverboard. These fans are 4U high and are powered by 4-pin connectors. Mounting Rails (optional) The SC745 can be placed in a rack for secure storage and use. To setup your rack, follow the step-by-step instructions included in this manual.
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. Most SC745 models have two buttons on the 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.
Chassis Manual 4-2 Control Panel Buttons There are two push-buttons located on the front of the chassis. These are the power on/off button and the reset button. • • 4-3 Power: The main power switch is used to apply or remove power from the power supply to the server system. Turning off the system power with this button removes the main power but keeps standby power supplied to the system. Therefore, you must unplug system before servicing. Reset: The reset button is used to reboot the system.
Chapter 4: System Interface • NIC2: Indicates network activity on GLAN2 when flashing. • NIC1: Indicates network activity on GLAN1 when flashing. • • HDD: Indicates IDE channel activity. SAS/SATA drive, SCSI drive, and/or DVDROM drive activity when flashing. Power: Indicates power is being supplied to the system's power supply units. This LED should normally be illuminated when the system is operating.
Chassis Manual 4-4 Drive Carrier LEDs Your chassis uses SAS/SATA or SCSI drives, but not both. SAS/SATA Drives Each SAS/SATA drive carrier has two LEDs. • • Green: Each SAS/SATA drive carrier has a green LED. When illuminated, this green LED (on the front of the SAS/SATA drive carrier) indicates drive activity. A connection to the SATA backplane enables this LED to blink on and off when that particular drive is being accessed. Red: The red LED to indicate an SAS/SATA drive failure.
