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.
SC846 Chassis Manual • 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 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.
SC846 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 SC846 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.
SC846 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. Reset: The reset button is used to reboot the system. 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.
Chapter 3: System Interface 2 NIC2: Indicates network activity on GLAN2 when flashing. 1 NIC1: Indicates network activity on GLAN1 when flashing. HDD: Indicates IDE channel activity. SAS/SATA drive, and/or DVD-ROM 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. ! Power Failure: When this LED flashes, it indicates a failure in the power supply.
SC846 Chassis Manual 3-4 Drive Carrier LEDs Your chassis uses SAS/SATA. SAS/SATA Drives Each SAS/SATA drive carrier has two LEDs. • Green: Each Serial ATA 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 SAS/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.
Chapter 4: Chassis Setup and Maintenance Chapter 4 Chassis Setup and Maintenance 4-1 Overview This chapter covers the steps required to install components and perform maintenance on the chassis.

Appendix D: BPN-SAS-846EL Backplane Specifications Dual Port and Cascading Configurations D-8 Single and Dual Port Expanders Single Ports SAS-846EL1 backplanes have a single-port expander that access all 24 drives and supports cascading. Dual Ports SAS-846EL2 backplanes have dual-port expanders that access all 24 drives. These dual-port expanders support cascading, failover, and recovery.
SC846 Chassis Manual D-9 Failover The SAS-846EL2 backplane has two expanders which allow effective failover and recovery. Single Host Bus Adapter SAS HBA PRI_J2 SEC_J2 SEC_J0 PRI_J1 SEC_J1 PRI_J0 WWN In a single host bus configuration, the backplane connects to one Host Bus Adapter (HBA).
Appendix D: BPN-SAS-846EL Backplane Specifications D-10 Chassis Power Card and Support Cables Chassis Power Card In a cascaded configuration, the first chassis includes a motherboard and at least one Host Bus Adapter (HBA). Other servers in this enclosed system, include a power card. This section describes the supported power card for the SAS-846 series backplane. For more information, see the PCC-JBPWR2 power card manual. This manual can be found at the http://www.supermicro.
SC846 Chassis Manual Connecting an Internal Host Bus Adapter to the Backplane The following section lists the most common cables used to connect the Host Bus Adapter (HBA) to the backplane.
Appendix D: BPN-SAS-846EL Backplane Specifications Cable Name: IPASS (mini SAS) TO IPASS (mini SAS) Part #: CBL-0108L-02 Length: 39 cm (15 inches) Part #: CBL-0109L-02 Length: 22 cm (9 inches) Part #: CBL-0110L-02 Length: 18 cm (7 inches) Description: This cable has an ipass (SFF-8087/mini-sas) connector (36 pins) at each end. It connects from the HBA to the SAS-846EL backplane.
SC846 Chassis Manual Connecting an External Host Bus Adapter to the Backplane This backplane supports external Host Bus Adapters. In this configuration, the HBA and the backplane are in different physical chassis. This allows a JBOD (Just a Bunch Of Drives) configuration from an existing system.
Appendix D: BPN-SAS-846EL Backplane Specifications Supported External HBA to Backplane Cable Use the following cable if your external HBA has an InfiniBand connector. Figure D-14: SAS InfiniBand Cable (CBL-0200L) Cable Name: SAS InfiniBand to Mini SAS X4 1M cable, PBF Part #: CBL-0200L Length: 1 meter Description: This cable has an InfiniBand connector (SFF-8470) on one end and an SFF-8088-1X (26-pins) at the other end.
SC846 Chassis Manual Connecting Multiple Backplanes in a Single Channel Environment This section describes the cables used when cascading from a single HBA. These connections use CBL-0167L internal cables and CBL-0166L external cables.

Connects the backplane to the Host Bus Adapter (HBA) or external port. Used in single port environments.
SC846 Chassis Manual Connecting Multiple Backplanes in a Dual Channel Environment This section describes the cables used when cascading from dual HBAs. These connections use CBL-0168L internal cables and CBL-0166L external cables.
Appendix D: BPN-SAS-846EL Backplane Specifications Dual HBA Configuration Cables Dual Port Cable Assembly Figure D-19: Dual Port Internal Cable (CBL-0168L) Cable Name: SAS Dual-port Cable Assembly, 68/76cm Part #: CBL-0168L Ports: Dual Placement: Internal cable Description: Internal cascading cable. Connects the backplane to the Host Bus Adapter (HBA) or external port. Used in dual port environments.
SC846 Chassis Manual D-11 Supported Cascading Configurations Cascading allows the system to access data at a faster rate by allowing several backplanes to share resources to reduce latency time. The first backplane in a cascaded system requires a motherboard and HBA. Other servers require a power control card with no motherboard and no HBA. For more information, see the SC846 Chassis Manual available at www.supermicro.com.
