1-2 Server Chassis Features
The SuperServer 8050 is a high-end, scaleable server platform designed with today's most state-of-the-art features. The following is a general outline of the main features of the SC850 server chassis.
System Power
A triple redundant power supply consisting of three 350W units provides 700W of continuous power with a 350W backup. If either working unit fails, you will be notified by alarm and the backup unit will automatically activate. These are hot-swap units that can be replaced without powering down the system.
SCSI Subsystem
The SCSI subsystem supports up to 10 80-pin SCA Ultra160 SCSI hard drives. (Any standard 1" drives are supported. SCA = Single Connection Attachment.) These can be configured as 10 drives on a single channel or 5 drives on two channels. The SCSI drives are connected to two SAF-TE compliant SCA backplanes that provide power, bus termination and configu­ration settings. The SCSI drives are also hot-swap units. A RAID controller card can be used with the SCA backplanes to provide data security. Note: The operating system you use must have RAID support to enable the hot-swap capability of the SCSI drives.
Front Control Panel
The SuperServer 8050's detailed control panel provides comprehensive system monitoring and control. LEDs indicate network activity, power sup­ply failure, fan failure, fan status, SCSI drive activity and failure and SCA backplane overheat conditions. The main power button, system reset but­ton and an alarm reset switch to disable audible alarms are also included.
l Six (6) VRMs (Voltage Regulator Modules) (MB)
You should also have received a User's Manual and Supermicro diskettes, which contains several drivers and utilities.

Chapter 1: Introduction
I/O Backplane
The SC850 is an SWTX form factor chassis. The SWTX I/O back panel provides nine motherboard expansion slots, two COM ports, a parallel port, two USB ports, PS/2 mouse and keyboard ports and an Ethernet port.
Cooling System
The SC850 chassis has an innovative cooling design that includes 9-cm hot­plug redundant system cooling fans and two airflow guides. All fans oper­ate continuously. If one fails, an alarm is activated and the RPM of the remaining fans increase to compensate and maintain sufficient airflow. Ad­ditional cooling for the SCSI drive bays is provided by two 12-cm exhaust fans.
1-3 Mainboard Features
At the heart of the SuperServer 8050 lies the S2QR6, a quad processor motherboard designed to provide maximum performance in a four-way sys­tem. Below are the main features of the S2QR6.
Processors
The S2QR6 supports Pentium III and II Xeon 100 MHz FSB processors in 1, 2, 3 and 4-way configurations. 400-700 MHz processors and future higher speed processors with a 100 MHz FSB will also be supported. Please refer to the support section of our web site for a complete listing of supported processors (http://www.supermicro.com/TechSupport.htm).
Memory
The MEC (Memory Expansion Card) included with your S2QR6 has 16 DIMM slots that can support up to 16 GB of registered DIMM with ECC. Module sizes of 128MB, 256MB, 512MB and 1 GB may be used to populate the MEC.
Onboard SCSI
Onboard SCSI is provided with an Adaptec AIC-7899 SCSI chip, which sup­ports dual channel, Ultra160 SCSI at a throughput of 160 MB/sec for each channel. The S2QR6 provides three SCSI ports: two 68-pin LVD Ultra160

Chapter 2
Quick Setup
2-1 Overview and Precautions
This chapter provides a quick setup checklist to get your SuperServer 8050 up and operating. Following these steps in the order given should enable you to have the system operating within a minimum amount of time. This quick setup assumes that your SuperServer 8050 system has come to you with processors and memory preinstalled. If your system is not already fully integrated with a motherboard, processors, system memory etc., please turn to the Chapter noted in each step for details on installing these components and configuring the system.
2-2 Setting up the SuperServer 8050
You should inspect the box the SuperServer 8050 was shipped in and note if it was damaged in any way. If the server itself shows damage you should file a damage claim with the carrier who delivered it.
Decide on a suitable place for setting up and operating the SuperServer
8050. You will need to place it in a clean, dust-free area that is well venti­lated. Avoid areas where heat, electrical noise and electromagnetic fields are generated. You will also need it placed near a grounded power outlet.
Once the 8050 is placed in the appropriate location, slide the locking tabs on each caster down to keep it stationary.
Checking the Motherboard Setup
Open the left side panel (when facing the front of the chassis) to make sure the motherboard is properly installed and all connections have been made.
1. Remove the left chassis side panel:
First, make sure the keylock for the side panels (located near the top at the rear of the chassis) is unlocked. Then remove the four screws that secure the back lip of the side panel to the rear of the chassis. Grasp the handle at the rear of the panel and pull straight back about 1/2 inch, at which point the panel should hit a stop. Swing the top of
2-2
SUPERSERVER 8050 Manual
the panel out and completely lift it away from the chassis. When reinstalling this panel, make sure the raised holes along the bottom of the chassis fit into the long holes in the bottom lip of the side panel.
2. Check the CPU core/bus ratio:
You should first verify that the CPU core/bus ratio as set with DIP switch 1 matches the speed of your installed processors. This DIP switch is defaulted to 5.5, which corresponds to 550 MHz processors running on a 100 MHz front side bus (FSB). If the setting is different or if you are using processors of a different speed, you may need to change this setting. See page 5-20 for setting the proper value with DIP switch 1. If your system came without processors, refer to page 5-6 for processor installation instructions.
3. Check the MEC:
The Memory Expansion Card (MEC) should be already installed and populated with DIMMs. Make sure the MEC is secure in its slot and that the retention plate is screwed firmly to the chassis. For details on populating the MEC, refer to page 5-8.
4. Install add-on cards:
Install any add-on cards that you want added to the system. See page 5-11 for details on installing add-on cards.
5. Check all cable connections and airflow:
Make sure all power and data cables are properly and firmly connected and not blocking the airflow. See page 5-4 for details on cable connections. Position the airflow guides to concentrate airflow to the processors and their heatsinks.
Checking the Drive Bay Setup
Open the right side panel to make sure the SCA backplanes are properly installed and all connections have been made.
1. Remove the right chassis side panel:
To access the drive bays, remove the right side panel (when facing the front of the chassis) by following the same procedures described on the previous page for removing the left side panel. You will also have to open the front doors on the right side of the chassis to access the front of the drive bays. These doors may be secured with a keylock located just below the system LEDs.
2. Install a CDROM and floppy disk drives:
See page 6-10 if you need to add a CDROM and/or floppy disk drive to the system.
Chapter 2: Quick Setup
2-3
3. Check the SCSI disk drives:
Depending upon your system's configuration, your system may have some SCSI drives already installed. If you need to install SCSI drives or wish to change the channel configuration, please refer to page 6-6. The drives are defaulted to a dual channel (channels A and B) configuration.
4. Check the airflow:
Because most of the excess cabling is kept on this side of the chassis, you should check to make sure all cables have been routed in such a way that they do not block the airflow generated by the fans.
5. Supply power to the system:
The last thing you must do is supply power to the system. Plug all three power cords from the three power supplies into a high-quality power strip that offers protection from electrical noise and surges.
2-3 Installing the Operating System
The SuperServer 8050 is normally shipped without an operating system (OS) installed. This is the last thing you need to do to make the system operational. The OS is normally installed with a CDROM. Refer to the documentation that came with your operating system to install it in the Su­perServer 8050.

Chapter 3
System Interface
3-1 Overview
There are several LEDs on the front control panel as well as others on the power supply units, the SCSI drives and the motherboard to keep you con­stantly informed of the overall status of the system as well as the activity and health of specific components. There are also three switches that allow you to take action based on the information provided by these LEDs. This chapter explains the meanings of all LED indicators and audible alarms and the appropriate responses you may need to take.
3-2 Switches
The front control panel has three push-button switches: a power on/ off switch, an alarm disable switch and a reset switch. These are ac­cessed by opening the top right door on the front of the chassis.
l POWER: This is the main power switch that will turn off the power supply.
l ALARM: Depressing the alarm switch will disable the audible alarm that is generated to notify you of chassis overheating or fan/power supply failure. The LED indicating the cause of the alarm will remain illuminated after the alarm is disabled.
l RESET: The reset switch reboots the system.
3-3 Front Control Panel LEDs
As shown in Figure 3-1, the front control panel of the SC850 chassis has eight LEDs. These LEDs keep you informed of the status of your system and indicate the following when illuminated.
l Power: Indicates power is being supplied to the system.
l NIC: Indicates network activity on the system.
l HDD: Indicates IDE drive activity.
SUPERSERVER 8050 Manual
3-2
l PWR Fault: Indicates a power supply failure. This should be accom- panied by an audible alarm, which you can disable with the alarm switch on the control panel. Inspect the power supply units at the rear of the chas­sis. The unit with the amber LED illuminated has failed. Refer to Chapter 6 for instructions on replacing the failed unit. Because they are hot-swap units, you do not need to remove power from the system when replacing.
l Fan Fail: Indicates a system fan failure. This should be accompanied by an audible alarm, which you can disable with the alarm switch on the control panel. When a fan stops working, all the other system fans will increase their RPM to compensate until the failed unit is replaced. Refer to Chapter 6 for instructions on replacing system fans. It is unnecessary to power down the system as these are hot-swap fans. Note: You must use the exact same brand and rating of fan for replacement. These can be obtained directly from Supermicro.
l Overheat: Indicates an overheat condition in the chassis.
l SCA Channel A: Indicates an overheat condition with SCA SCSI back
plane A (which supports the upper drive bays).
l SCA Channel B: Indicates an overheat condition with SCA SCSI back plane B (which supports the lower drive bays).

3-4 SCSI Drive LEDs
Each SCSI drive carrier has two LEDs.
l Green: The green SCSI drive LED indicates drive activity. This LED should blink on and off when that particular drive is being accessed.
l Red: If the red LED is illuminated, the drive has experienced a fault or has crashed. Please refer to Chapter 6 for instructions on replacing failed SCSI drives.
3-5 Power Supply LEDs
Each of the three units comprising the power supply has a single LED that can be illuminated either as green or amber.
l Green: When green, the unit has power applied to it and is operating normally.
l Amber: If the LED is amber, it indicates that no power is being applied to that unit. If system power has been turned off this is normal, however if the system is powered on and running an amber LED most likely indicates a failed power unit. First check to make sure the power cord for that unit is plugged in. If it is, then refer to Chapter 6 for instructions on replacing the unit. The power unit's fan may continue to run at low speed even if the unit has failed or has been turned off.
3-6 Motherboard LED
There is only one LED on the motherboard. When illuminated, it indicates that system power is present on the motherboard. This LED is located just below the PWR_SEC connector, which is at the top right corner of the board when installed in the chassis. It provides the same indication as the Power LED on the front control panel.

4-1 Electrical Safety Precautions
!
Basic electrical safety precautions should be followed to protect yourself from harm and the SuperServer 8050 from damage:
l 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.
l Do not work alone when working with high voltage components.
l Power should always be disconnected from the system when
removing or installing main system components, such as the motherboard, the MEC, memory modules and IDE and floppy drives. When disconnecting power, you should first power down the system with the operating system first and then unplug the power cords of all the power supply units in the system.
l When working around exposed electrical circuits, another person
who is familiar with the power-off controls should be nearby to switch off the power if necessary.
l Use only one hand when working with powered-on electrical
equipment. This is to avoid making a complete circuit, which will cause electrical shock. Use extreme caution when using metal tools, which can easily damage any electrical components or circuit boards they come into contact with.
l Do not use mats designed to decrease static electrical discharge as
protection from electrical shock. Instead, use rubber mats that have been designed as electrical insulators.
l The power supply power cords must include a grounding plug and
must be plugged into grounded electrical outlets.
SUPERSERVER 8050 Manual

4-2 General Safety Precautions
Follow these rules to ensure general safety:
l Keep the area around the SuperServer 8050 clean and free of
clutter.
l The SuperServer 8050 weighs approx. 84 lbs. (38 kg.) If you have
to lift the system, two people at either end should lift slowly with their feet spread out to distribute the weight. Always keep your back straight and lift with your legs.
l Place side panels and any system components that have been
removed away from the system so that they won't accidentally be stepped on.
l While working on the system, do not wear loose clothing such as
neckties and unbuttoned shirt sleeves that can come into contact with electrical circuitry or be pulled into the one of the cooling fans.
l Remove any jewelry or metal objects from your body, which are
excellent metal conductors that can create short circuits and harm you if they come into contact with printed circuit boards or areas where power is present.
l After servicing the system, reinstall all covers and side panels and
ensure all connections have been made.
!
l Motherboard Battery: CAUTION - There is a danger of explosion if
the onboard battery (located near the MEC and IDE#2 connectors) is installed upside down, which will reverse its polarites. This battery must be replaced only with the same or an equivalent type recommended by the manufacturer. Dispose of used batteries according to the manufacturer's instructions.

4-3 ESD Precautions
Electrostatic discharge (ESD) is generated by two objects with different electrical charges coming into contact with each other. An electrical discharge is created to neutralize this difference, which can damage electronic components and printed circuit boards. The following measures are generally sufficient to neutralize this difference before contact is made to protect your equipment from ESD:
l Use a grounded wrist strap designed to prevent static discharge.
l Keep all components and printed circuit boards (PCBs) in their
antistatic bags until ready for use.
l Touch a grounded metal object before removing the board from the antistatic bag.
l 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.
l Handle a board by its edges only; do not touch its components, peripheral chips, memory modules or gold contacts.
l When handling chips or modules, avoid touching their pins.
l Put the motherboard and peripherals back into their antistatic bags
when not in use.
l For grounding purposes, make sure your computer chassis provides excellent conductivity between the power supply, the case, the mounting fasteners and the motherboard.

Advanced Motherboard Setup
This chapter covers the steps required to install the S2QR6 motherboard into a chassis, connect the data and power cables and install add-on cards. All motherboard jumpers and connections are also described. A layout and quick reference chart are on pages 5-12 and 5-13. Remember to remount the side panel when you have finished with the installation to better cool and protect the system.
Tools Required
The only tools you will need to install the S2QR6 into a chassis are a long and a short Philips screwdriver.
5-1 Handling the S2QR6 Motherboard
Static electrical discharge can damage electronic components. To prevent damage to any printed circuit boards (PCBs), it is important to handle them very carefully. Also note that the size and weight of the S2QR6 mother­board can cause it to bend if handled improperly, which may result in dam­age. To prevent the S2QR6 motherboard from bending, keep one hand under the center of the board to support it when handling. The following measures are generally sufficient to protect your equipment from static discharge.
Precautions
• Use a grounded wrist strap designed to prevent static discharge.
• Touch a grounded metal object before removing any board from its anti­static bag.
• Handle a board by its edges only; do not touch its components, periph­eral chips, memory modules or gold contacts.
• When handling chips or modules, avoid touching their pins.
• Put the motherboard, add-on cards and peripherals back into their anti­static bags when not in use.

5-2 Motherboard Installation
This section explains the first step of physically mounting the S2QR6 into the SC850 chassis. To remove the motherboard, follow the procedure in reverse order. Following the steps in the order given will eliminate the most common problems encountered in such an installation.
1. Removing the left chassis side panel:
The left side panel (when facing the chassis) must be removed to access the motherboard side of the chassis. First, make sure the keylock for the side panels (located at the top rear of the chassis) is unlocked. Then remove the four screws that secure the lip of the side panel to the back of the chassis. Grasp the handle at the rear of the panel and pull straight back about 1/2 inch, at which point the panel should hit a stop. Swing the top of the panel out and com­pletely lift it away from the chassis. When reinstalling this panel, make sure the raised holes along the bottom of the chassis fit into the long holes in the bottom lip of the panel.
2. Installing metal standoffs and rubber feet:
With the side panel removed, the motherboard tray is directly in front of you. First, check that the location of all the mounting holes on both the motherboard and the tray match. Refer to Figure 5-1 for mounting hole locations. Attach metal standoffs to the holes labeled "Q" on the motherboard tray. Make sure these metal standoffs either click in or are screwed in tightly. There are eight additional square metal standoffs that are required for mounting the DRMs (Dual Retention Modules), which should be preinstalled. Several square rubber "feet" must be applied to the motherboard tray to function as shock absorbers. Attach these feet to the small square outlines on the tray.
• For grounding purposes, make sure your computer chassis provides ex­cellent conductivity between the power supply, the case, the mounting fasteners and the motherboard.
Unpacking
The motherboard is shipped in antistatic packaging to avoid static electrical damage. When unpacking the board, make sure the person handling it is static protected.
