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 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 HDD: Indicates IDE channel activity. SAS/SATA drive, and/or DVD-ROM drive activity when flashing. 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.
SC846 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.
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. 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.

Chapter 5: Rack Installation Chapter 5 Rack Installation 5-1 Overview This chapter provides a quick setup checklist to install the chassis into a rack. Following these steps in the order given should enable you to have the system installed within a minimal amount of time. 5-2 Unpacking the System You should inspect the box which the chassis was shipped in and note if it was damaged in any way. If the chassis itself shows damage, you should file a damage claim with the carrier who delivered it.
SC846 Chassis Manual 5-4 • Warnings and Precautions Rack Precautions Ensure that the leveling jacks on the bottom of the rack are fully extended to the floor with the full weight of the rack resting on them. • In single rack installations, stabilizers should be attached to the rack. • In multiple rack installations, the racks should be coupled together. • • • • • • • • Always make sure that the rack is stable before extending a component from the rack.
Chapter 5: Rack Installation Rack Mounting Considerations Ambient Operating Temperature If installed in a closed or multi-unit rack assembly, the ambient operating temperature of the rack environment may be greater than the ambient temperature of the room. Therefore, consideration should be given to installing the equipment in an environment compatible with the manufacturer’s maximum rated ambient temperature (TMRA).
SC846 Chassis Manual 5-6 Rack Mounting Instructions This section provides information on installing the chassis into a rack unit with the rails provided. There are a variety of rack units on the market, which may mean that the assembly procedure will differ slightly from the instructions provided. You should also refer to the installation instructions that came with the rack unit you are using. NOTE: This rail will fit a rack between 26.5" and 36.4" deep.
Chapter 5: Rack Installation Locking Tabs Each inner rail has a locking tab. This tab locks the chassis into place when installed and pushed fully into the rack. These tabs also lock the chassis in place when fully extended from the rack. This prevents the server from coming completely out of the rack when when the chassis is pulled out for servicing. Releasing the Inner Rail Releasing Inner Rail from the Outer Rails 1. Identify the left and right outer rail assemblies as described on page 5-4. 2.

Appendix F: SC846B Chassis Specifications Installing the Hard Drive Assembly 1. Disconnect the power from the chassis by unplugging the power cord. 2. Remove the screws securing the dummy cover into the rear peripheral drive bay. This bay is located on the rear of the chassis beside the power supplies. 3. Lift the dummy cover up and out of the peripheral drive bay. 13 12 Figure F-7: Removing the Dummy Cover from the Peripheral Drive Bay 4.
SC846 Chassis Manual 6. Remove the dummy drives from the hard drive carriers. 7. Insert a drive into the carrier with the PCB side facing down and the connector end toward the rear of the carrier. 8. Align the drive in the carrier so that the mounting holes of both are aligned. Note that there are holes in the carrier marked "SAS" or “SATA” to aid in correct installation. 9. Secure the drive to the carrier with four screws as illustrated above.
