1-3 Server Chassis Features

The SuperServer 8042-8/8042-6 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 SC862 server chassis.

System Power

The 8042-8/8042-6 features a triple redundant power supply consisting of
three hot-swappable 350 watt power modules, which supply 700 watts of
continuous power with a 350 watt backup. If any of the three modules fail,
you will be notified by an alarm and an LED and the remaining two modules
will take up the load. The alarm reset button located on the control panel
can be depressed to deactivate the power fail alarm.

SCSI Subsystem

The SCSI subsystem supports up to four 80-pin SCA Ultra320 (8042-8) or
Ultra160 SCSI (8042-6) hard drives. (Any standard 1" drives are sup­ported. SCA = Single Connection Attachment.) The SCSI drives are con­nected to an SCA backplane. The SCSI drives are hot-swap units. A RAID
controller card can be used with the SCA backplane 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 control panel on the SuperServer 8042-8/8042-6 provides you with
system monitoring and control. LEDs indicate network activity, power sup­ply failure, fan failure, SCSI drive activity and failure and SCA backplane
overheat conditions. A main power button, a system reset button and an
alarm reset switch are also included.

I/O Backplane

The SC862 is a 4U rackmount, WTX form factor chassis. The I/O backplane
provides seven expansion slots, one COM port, one VGA port, a parallel
port, two USB ports, PS/2 mouse and keyboard ports and an Ethernet port.

1-5

Chapter 1: Introduction

Cooling System

The SC862 chassis has an innovative cooling design that includes four 9­cm hot-plug redundant system cooling (intake) fans and two 9-cm exhaust
fans. All system fans (located between the drive bays and the
serverboard) operate continuously. If one fails, an alarm is activated and
the RPM of the remaining fans increase to compensate and maintain suffi­cient airflow.

Chapter 2

Server Installation

2-1 Overview

This chapter provides a quick setup checklist to get your SuperServer 8042­8/8042-6 up and running. Following these steps in the order given should
enable you to have the system operational within a minimum amount of time.
This quick setup assumes that your SuperServer 8042-8/8042-6 system
has come to you with the processors and memory preinstalled. If your
system is not already fully integrated with a serverboard, processors, sys­tem memory etc., please turn to the chapter or section noted in each step
for details on installing the specific component.

2-2 Unpacking the SuperServer 8042-8/8042-6

You should inspect the box the SuperServer 8042-8/8042-6 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 location for the rack unit that will hold the SuperServer
8042-8/8042-6. It should be situated 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. Read the Rack and Server Precautions in the next section.

2-3 Preparing for Setup

The box the SuperServer 8042-8/8042-6 was shipped in should include two
sets of rail assemblies, two rail mounting brackets and the mounting screws
you will need to install the system into the rack. Follow the steps in the
order given to complete the installation process in a minimum amount of time.
Please read this section in its entirety before you begin the installation
procedure outlined in the sections that follow.

2-2

SUPERSERVER 8042-8/8042-6 Manual

Choosing a Setup Location:

- Leave enough clearance in front of the rack to enable you to open

the front door completely (~25 inches).

- Leave approximately 30 inches of clearance in the back of the rack

to allow for sufficient airflow and ease in servicing.

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 installation, stabilizers should be attached to the rack.

- In multiple rack installations, the racks should be coupled together.

- Always make sure the rack is stable before extending a component

from the rack.

- You should extend only one component at a time - extending two or

more simultaneously may cause the rack to become unstable.

Server Precautions:

- Review the electrical and general safety precautions in Chapter 4.

- Determine the placement of each component in the rack before you

install the rails.

- Install the heaviest server components on the bottom of the rack

first, and then work up.

- Use a regulating uninterruptible power supply (UPS) to protect the
server from power surges and voltage spikes and to keep your
system operating in case of a power failure.

- Allow the hot plug SCSI drives and power supply units to cool before

touching them.

- Always keep the rack's front door and all panels and components on

the servers closed when not servicing to maintain proper cooling.

2-4 Installing the 8042-8/8042-6 into a Rack

This section provides information on installing the SuperServer 8042-8/
8042-6 into a rack unit. If the 8042-8/8042-6 has already been mounted into
a rack, you can skip ahead to Sections 2-5 and 2-6. There are a variety of
rack units on the market, which may mean the assembly procedure will
differ slightly. The following is a guideline for installing the 8042-8/8042-6
into a rack with the rack rails provided. You should also refer to the
installation instructions that came with the rack unit you are using.

Identifying the Sections of the Rack Rails:

You should have received two rack rail assemblies with the SuperServer
8042-8/8042-6. Each of these assemblies consist of three sections: an
inner fixed chassis rail that secures to the 8042-8/8042-6 (A), an outer
fixed rack rail that secures directly to the rack itself (B), and a sliding rail
guide (C) between the two, which should remain attached to the fixed
rack rail. (See Figure 2-1, which shows the chassis rail 'A' already
attached to the chassis).

The first thing you must do is to remove the fixed chassis rail (A) from
each assembly. To do this, pull this inner rail out as far as possible

- you should hear a "click" sound as a locking tab emerges from inside
the rail assembly and locks the inner rail. Depress the locking tab to pull
the inner rail completely out.

Figure 2-1. Identifying the Sections of the Rack Rails

2-4

SUPERSERVER 8042-8/8042-6 Manual

Installing the Chassis Rails:

Position the fixed chassis rail sections you just removed along the side of
the 8042-8/8042-6 chassis making sure the five screw holes line up. Be
aware that these two rails are left/right specific. Screw the rail securely
to the side of the chassis (see Figure 2-2). Repeat this procedure for
the other rail on the other side of the chassis.

Locking Tabs: As you have seen, both chassis rails have a locking tab,
which serves two functions. The first is to lock the server into place
when installed and pushed fully into the rack, which is its normal position.
These tabs also lock the server in place when fully extended from the
rack. This prevents the server from coming completely out of the rack
when you pull it out for servicing.

Figure 2-2. Installing the Chassis Rails

Installing the Rack Rails:

Determine where you want to place the 8042-8/8042-6 in the rack.
(See Rack and Server Precautions in Section 2-3.) Position the fixed rack
rail/sliding rail guide assemblies at the desired location in the rack,
keeping the sliding rail guide facing the inside of the rack. Screw the
assembly securely to the rack using the brackets provided. Attach the
other assembly to the other side of the rack, making both are at the exact
same height and with the rail guides facing inward (see Figure 2-3).

Figure 2-3. Installing the Rack Rails

Installing the Server Into the Rack:

You should now have rails attached to both the chassis and the rack
unit. The next step is to install the server into the rack. Do this by
lining up the rear of the chassis rails with the front of the rack rails.
Slide the chassis rails into the rack rails, keeping the pressure even on
both sides (you may have to depress the locking tabs when inserting).
See Figure 2-4 on the next page.

When the server has been pushed completely into the rack, you should
hear the locking tabs "click". Finish by inserting and tightening the
thumbscrews that hold the front of the server to the rack.

2-5 Checking the Serverboard Setup

After you install the 8042-8/8042-6 in the rack, you will need to open the
unit to make sure the serverboard is properly installed and all the connec­tions have been made.

1. Accessing the inside of the 8042-8/8042-6 (see Figure 2-5):

First, release the retention screws that secure the unit to the rack.
Next, release the two thumbscrews that secure the top cover to the
chassis. Grasp the two handles on either side and pull the unit
straight out until it locks (you will hear a "click"). There are two
square recesses in the top cover to help you push the cover away
from you until it stops. You can then lift the top cover from the
chassis. You now have full access to the inside of the server.

2. Check the CPUs (processors):

The processors are enclosed in an air shroud. You should one to four
processors fully inserted into the serverboard. Each processor should
have its own heatsink attached. See Chapter 5 for instructions on
processor installation.

3. Check the MEC:

The Memory Expansion Card (MEC) should be already installed. Make
sure the MEC is fully seated in its slot and that its retention plate is
screwed firmly to the chassis. For details on populating the MEC,
refer to Chapter 5.

4. Installing add-on cards:

Install any add-on cards that you want added to the system. See
Chapter 5 for details on installing PCI 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 Chapter 5 for details on cable
connections.

2-6 Checking the Drive Bay Setup

Next, you should check to make sure the peripheral drives and the SCA
drives and backplane have been properly installed and all connections have
been made.

1. Accessing the drive bays:

All drives can be accessed from the front of the server. For servicing
the CD-ROM and floppy drives, you will need to remove the top
chassis cover. The SCSI disk drives can be installed and removed
from the front of the chassis without removing the top chassis cover.

2. Installing a CD-ROM and floppy disk drives:

Refer to Chapter 6 if you need to reinstall a CD-ROM and/or floppy disk
drive to the system.

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,
please refer to Chapter 6.

4. Check the airflow:

Airflow is provided by four hot-swap input fans and two exhaust fans,
all of which are 9-cm in size. Also note that all power and data
cables have been routed in such a way that they do not block the
airflow generated by the fans. Make sure you reroute them in this
fashion if you disconnect them when adding or removing components.

5. Supplying 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 supply units into a high­quality power strip that offers protection from electrical noise and
power surges. It is recommended that you use an uninterruptible
power supply (UPS).

Chapter 3

System Interface

3-1 Overview

There are several LEDs on the control panel as well as others on the power
supply units, the SCSI drive carriers and the serverboard 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 response you may need to take.

3-2 Control Panel Switches

There are three push-button switches located on the front of the chassis.
These are (in order from left to right) a power on/off switch, an alarm
disable switch and a reset switch.

! POWER: This is the main power switch, which is used to apply or

remove the power from the power supply units on the server.

! ALARM: Depressing the alarm switch will disable the audible alarm,

which is generated to notify you of chassis overheating or a fan/power
supply failure. The LED indicating the cause of the alarm will remain illumi­nated after the audible alarm is disabled.

! RESET: The reset switch reboots the system.

3-3 Control Panel LEDs

The control panel located on the front of the SC862 chassis has seven
LEDs. These LEDs provide you with critical information related to different
parts of the system. This section explains what each LED indicates when
illuminated and any corrective action you may need to take.

! Power: Indicates power is being supplied to the system's power

supply units. This LED should normally be illuminated when the system is
operating.

! NIC: Indicates network activity on the system when flashing.

! HDD: Indicates IDE channel activity. On the SuperServer 8042-8/

8042-6, this light indicates CD-ROM drive activity when flashing.

! PWR Fault: Indicates a power supply failure. This should be ac-

companied by an audible alarm, which you can disable with the alarm
switch on the control panel. Inspect the power supply modules at the front
left of the chassis. The module with the red LED illuminated has failed.
Refer to Chapter 6 for instructions on replacing the failed module. Because
the power supplies are hot-pluggable, you do not need to remove power

Chapter 3: System Interface

3-3

from the system when replacing. (All three power supply modules are
normally active - if one module fails the other two take up the load to keep
the system running.)

! Fan Fail: Indicates a system fan failure. This may be one or more of

the four hot-swap intake fans or the two exhaust fans. A fan failure is
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 (see Chapter 6 for more details.) 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.

! Overheat: Indicates an overheat condition in the chassis. This may

be caused by cables obstructing the airflow in the system, or the ambient
room temperature being too warm. You should also check to make sure
that the chassis cover is installed and that all fans are present and operat­ing normally.

! SCA Channel: Indicates an overheat condition in the area of the

SCA SCSI drives and backplane. This may be caused by cables obstructing
the airflow in the system, or the ambient room temperature being too warm.
You should also check to make sure that the chassis cover is installed and
that all fans are present and operating normally.

SUPERSERVER 8042-8/8042-6 Manual

3-4

3-4 SCSI Drive Carrier LEDs

Each SCSI drive carrier has two LEDs.

! Green: When illuminated, the green LED on the front of the SCSI drive

carrier indicates drive activity. A connection to the SCSI SCA backplane
enables this LED to blink on and off when that particular drive is being
accessed.

! Red: When illuminated, the red LED on the front of the SCSI drive

carrier indicates 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 separate power units that comprise the power supply has
a single LED that can be illuminated either as green or red.

! Green: When green, the power unit has power applied to it and is

operating normally.

! Red: A red LED is normal only when system power has been turned

off. If the LED is red, it indicates that either (1) no power is being applied
to that particular power unit or (2) that particular power unit has failed.
First check to make sure the power cord for that unit is plugged into both
the power unit and a grounded wall outlet/power strip. If the power cord is
properly connected, not, refer to Section 6-5 for instructions on replacing
the power supply unit.

Chapter 4

System Safety

4-1 Electrical Safety Precautions

!

Basic electrical safety precautions should be followed to protect yourself
from harm and the SuperServer 8042-8/8042-6 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.

! Power should always be disconnected from the system when removing or

installing main system components, such as the serverboard, memory
modules and the CD-ROM and floppy drives. When disconnecting power,
you should first power down the system with the operating system and
then unplug the power cords of all the power supply units in the system.

! 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.

! 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.

! Do not use mats designed to decrease electrostatic discharge as protection

from electrical shock. Instead, use rubber mats that have been specifically
designed as electrical insulators.

! The power supply power cord must include a grounding plug and must be

plugged into grounded electrical outlets.

SUPERSERVER 8042-8/8042-6 Manual

4-2 General Safety Precautions

Follow these rules to ensure general safety:

! Keep the area around the SuperServer 8042-8/8042-6 clean and free of

clutter.

! The SuperServer 8042-8/8042-6 weighs approximately 70 lbs (32 kg) when

fully loaded. When lifting 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.

! Place the chassis top/side 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.

! 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.

!

! Serverboard Battery: CAUTION - There is a danger of explosion if the onboard

battery is installed backwards, which will reverse its polarities. The positive
side of the battery should be facing up and the negative side should facing
the serverboard. 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.

! CD-ROM Laser: CAUTION - this server may have come equipped with a CD-

ROM drive. To prevent direct exposure to the laser beam and hazardous
radiation exposure, do not open the enclosure or use the unit in any
unconventional way.

Chapter 4: System Safety

4-3

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:

! Use a grounded wrist strap designed to prevent static discharge.

! Keep all components and printed circuit boards (PCBs) in their antistatic

bags until ready for use.

! Touch a grounded metal object before removing a 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.

! 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.

!

! After accessing the inside of the system, close the system back up and (if

rackmounted) secure it to the rack unit with the retention screws after
ensuring that all connections have been made.

SUPERSERVER 8042-8/8042-6 Manual

4-4 Operating Precautions

Care must be taken to assure that all chassis covers are in place when the
8042-8/8042-6 is operating to ensure proper cooling. Out of warranty damage
to the 8042-8/8042-6 system can occur if this practice is not strictly followed.

Chapter 5

Advanced Serverboard Setup

This chapter covers the steps required to install the processors and
heatsinks, connect the data and power cables and install add-on cards. All
serverboard jumpers and connections are also described. A layout and
quick reference chart are included in Section 5-7. Remember to close the
chassis completely when you have finished working on the serverboard to
sufficiently cool and protect the system.

5-1 Handling the P4QH8/P4QH6 Serverboard

Static electrical discharge can damage electronic components. To prevent
damage to any printed circuit boards (PCBs), it is important to handle them
very carefully (see previous chapter). Also note that the size and weight
of the serverboard can cause it to bend if handled improperly, which may
result in damage. To prevent the serverboard 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 serverboard, add-on cards and peripherals back into their anti­static bags when not in use.

Unpacking

The serverboard is shipped in antistatic packaging to avoid static damage.
When unpacking the board, make sure the person handling it is static pro­tected.

5-2

SUPERSERVER 8042-8/8042-6 Manual

IMPORTANT: Always connect the power cords last and always remove
them before adding, removing or changing any hardware components.
Make sure that you install the processor into the CPU socket before you
install the heatsink.

!

5-2 PGA Processor and Heatsink Installation

When handling the processor package, avoid placing direct
pressure on the label area of the fan. Also, do not place the
serverboard on a conductive surface, which can damage the
BIOS battery and prevent the system from booting up.

5-3 Connecting Cables

Now that the processors and heatsinks are installed, the next step is to
connect the cables to the serverboard and install memory. Cables include
the data (ribbon) cables for the peripherals and control panel and the power
cables.

Connecting Data Cables

The ribbon cables used to transfer data from the peripheral devices have
been carefully routed in preconfigured systems to prevent them from block­ing the flow of cooling air that moves through the system from front to back.
If you need to disconnect any of these cables, you should take care to keep
them routed as they were originally after reconnecting them (make sure the
red wires connect to the pin 1 locations). If you are configuring the system
yourself, keep the airflow in mind when routing the cables. The following
data cables (with their serverboard connector locations noted) should be
connected. See the serverboard layout figure in this chapter for connector
locations. See Section 5-8 for data cable pin definitions.

! IDE Device Cables (J14, J15)

! Floppy Drive Cable (J19)

! Ultra320/160 LVD SCSI Cables (JA1 and JA2)

! Control Panel Cable (JF1, see next page)

Connecting Power Cables

The P4QH8/P4QH6 has a 24-pin primary power supply connector desig­nated "ATX Power" for connection to the ATX power supply. There are
also 8-pin and 4-pin power connectors which must be connected to your
power supply. See Section 5-8 for power connector pin definitions.

Chapter 5: Advanced Serverboard Setup

Figure 5-3. JF1: Front Control Panel Header Pins

Connecting the Control Panel

JF1 contains header pins for various front control panel connectors. See
Figure 5-3 for the pin locations of the various front control panel buttons
and LED indicators. Please note that even and odd numbered pins are on
opposite sides of each header.

All JF1 wires have been bundled into a single ribbon cable to simplify their
connection. Make sure the red wire plugs into pin 1 as marked on the
board. The other end connects to the Control Panel printed circuit board,
located just behind the system status LEDs in the chassis.

5-4 Installing Memory in the MEC

Note: Check the Supermicro web site for recommended memory modules:

http://www.supermicro.com/TECHSUPPORT/FAQs/Memory_vendors.htm

CAUTION

Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage. The MEC must be

populated in the manner described in Step 2 below.

Memory Support: The P4QH8/P4QH6 supports 128MB/256MB/512MB/
1GB and 2GB ECC registered DDR200 (PC1600) SDRAM DIMM memory
modules. Non-ECC or unbuffered SDRAM memory is not supported.

1. Removing the MEC (Memory Expansion Card):

You should remove the MEC whenever installing or removing DIMMs. The
MEC is attached to a retention plate with seven screws. Do not remove
these. Instead, remove only the two screws that secure the MEC
retention plate to the chassis (one on each end). After removing the
board, place it on an antistatic bag before inserting the DIMMs.

2. Populating the MEC:
Important: Because memory is accessed by a four-way interleaving

scheme, you must install modules four at a time and in the order shown
in Figure 5-4 and described here: Always install DIMMs from the bottom
of the MEC card up and in groups of four. If four DIMMs are to be
installed, you must populate the four DIMM slots along the bottom of the
MEC (see Figure 5-4). If eight are to be installed, you must populate the
eight bottom DIMM slots, and so on. It is recommended that all installed
DIMMs be the same brand, type, size and speed.

3. Inserting DIMMs:

Insert each DIMM module vertically into its slot. Pay attention to the notch
along the bottom of the module to prevent inserting it incorrectly. Gently
press down on the DIMM module until it snaps into place in the slot (see
Figure 5-5). If you use too much pressure when inserting the DIMMs you
may bend and damage the MEC.

Chapter 5: Advanced Serverboard Setup

5-9

Figure 5-4. Populating the MEC

(Four DIMM installation shown)

4. Installing the MEC:

After populating the MEC, carefully install it back into its slot on the
serverboard, making sure it is fully seated. Finish by securing each end
of the retention plate to the chassis with the two screws you removed
as described in step one.

Note: Always install DIMMs from the bottom of the MEC card up and in
groups of four. If four DIMMs are to be installed, you must populate the
four DIMM slots along the bottom of the MEC (as shown in Figure 5-4). If
eight are to be installed, you must populate the eight bottom DIMM slots,
and so on.

5-10

SUPERSERVER 8042-8/8042-6 Manual

Figure 5-5. Side and Top View of DIMM Installation into Slot

To Install: Insert module vertically and press down until it snaps into
place. Pay attention to the bottom notch.
To Remove: Use your thumbs to gently push each release tab outward
to free the DIMM from the slot.

Chapter 5: Advanced Serverboard Setup

5-11

5-5 Adding PCI Cards

1. PCI expansion slots:

The P4QH8/P4QH6 system board has six 64-bit 100 MHz PCI-X slots. The
backplane of the 8042-6 has seven I/O slots that allows you to have a
full complement of PCI cards installed on the system.

2. PCI card installation:

Begin by removing the I/O shield from the backplane of the server
corresponding to the PCI slot you wish to populate. Insert the card into
the slot on the serverboard, pushing down with your thumbs evenly on
both sides of the card. Finish by using a screw to secure the top of the
card shield to the chassis. The I/O shields protect the serverboard and
its components from EMI (electromagnetic interference) and aids in proper
ventilation of the server, so make sure there is always a shield covering
each slot.

5-6 I/O Ports

The I/O ports are color coded in conformance with the PC 99 specification.
See Figure 5-6 below for the colors and locations of the various I/O ports.

Reading the Debug LEDs:

When on, each of the eight separate
LEDs represent the value shown to
the left of it in the diagram. Add up
the values of the illum inated LE Ds in
D13 to D16 to get the low (right) digit
and those in D17 to D20 to get the
high (left) digit of the corresponding
hexidecimal POST code.

Example:

The example on the left indicates a
hexidecim al P OS T cod e of C6 . This is
determined in the following mann er:
D17-D20 (high digit): 8 + 4 = 12
(decimal 12 = hexidecimal C)

Chapter 6

Advanced Chassis Setup

This chapter covers the steps required to install components and perform
maintenance on the SC862 chassis. For component installation, follow the
steps in the order given to eliminate the most common problems encountered.
If some steps are unnecessary, skip ahead to the step that follows.

Tools Required

The only tool you will need to install components and perform
maintainance is a Philips screwdriver.

6-1 Static-Sensitive Devices

Static electrical discharge can damage electronic components. To prevent
damage to any printed circuit boards (PCBs), it is important to handle them
very carefully. 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 anti-

static bag.

! Handle a board by its edges only; do not touch its components, periph-

eral chips, memory modules or gold contacts.

! When handling chips or modules, avoid touching their pins.
! Put the serverboard, add-on cards and peripherals back into their anti-

static bags when not in use.

! For grounding purposes, make sure your computer chassis provides ex-

cellent conductivity between the power supply, the case, the mounting
fasteners and the serverboard.

Unpacking

The serverboard is shipped in antistatic packaging to avoid static damage.
When unpacking the board, make sure the person handling it is static pro­tected.

status and alarm indications. A ribbon cable has bundled these wires
together to simplify the connection. Connect the cable from JF1 on the
serverboard (making sure the red wire plugs into pin 1) to JP9 on the
Control Panel PCB (printed circuit board). Pull all excess cabling out of
the airflow path. The LEDs inform you of system status. See Chapter 3:
System Interface for details on the LEDs and the control panel buttons.

SUPERSERVER 8042-8/8042-6 Manual

6-3 System Fans

Four 9-cm hot-swap system cooling fans provide are located side by side
between the serverboard bay and the front section of the chassis.
There are also two 9-cm exhaust fans, which are located at the back of
the chassis to pull the cool intake air through the system and force the
hot air out.

System Fan Failure

Under normal operation, all six system fans run at 80% of their maximum
speed, which supplies sufficient airflow while prolonging fan life. If any
fan fails, the rest will automatically increase their RPM to a full 100% to
compensate. An audible alarm and an LED on the control panel will notify
you of any fan failure. You can disable the alarm with the alarm button
on the control panel. The system cooling fans are hot-swap components,
which allows you to replace them without powering down the system.

Identifying the failed fan

To determine which fan has failed, first remove the top chassis cover.
You can then check the fan fail LEDs on the control panel's printed circuit
board (PCB), which can be viewed through a cutout on its protective
metal cover. See the designation written by the red illuminated LED on
the PCB to determine which fan has failed (Figure 6-2). After determining
whether it is a cooling or an exhaust fan and the number (position), you
should refer to the following two sections for instructions on replace­ment.

Fan Power Override Switch: Turn this switch ON to manually supply
power to the system fans. The default setting for this switch is OFF. The
system cooling fans normally run at 80% of their maximum RPM to allow for
this backup compensation and promote fan life. Turning the fan power
override switch to ON overrides the 80% RPM feature to make all fans run
at their 100% RPM rate. The microcontroller will continue to monitor for fan
fail when this switch is turned on. You should do this if you want to supply
maximum cooling to the system or if the microcontroller malfunctions.

Chapter 6: Advanced Chassis Setup

Figure 6-3. System Cooling Fan Removal

Replacing System Cooling Fans

1. Removing a system cooling fan:

With the chassis cover removed, first unplug the fan cable corresponding
to the failed fan. Then remove the fan unit from the chassis by depress­ing the locking tab on the fan housing and pulling the unit straight up (see
Figure 6-3). Take apart the fan housing to remove the fan from inside.

2. Installing a new system cooling fan:

Replace the failed fan with an identical 9-cm, 12 volt fan (available from
Supermicro). After the new fan has been installed, reassemble the fan
housing and plug it back into its slot. You should hear it click into place
when fully inserted. Then plug the fan cable back into the same header
on the circuit board you removed it from. You should then wind the
excess cable around the tabs on the fan housing to keep it out of the
way. Check that the fan is working properly and that all the LEDs on the
control panel circuit board (Figure 6-2) and the control panel have turned
off. Finish by replacing the top panel of the chassis.

Note: Only a "slim" CD-ROM drive will fit in the 8042-8/8042-6.

Replacing System Exhaust Fans

1. Removing a hot-plug fan housing:

With the chassis cover removed, first unplug the fan cable corresponding
to the failed fan. Next, push down on the locking tabs at the top and
bottom of the fan housing, which protrude through the back end of the
chassis. This will detach the housing from the chassis. Reach inside the
chassis and pull the housing out of its hole in the chassis. Unscrew the
four screws that hold the fan in the housing to remove the bad fan.

2. Installing a new system exhaust fan:

Replace the failed fan with an identical 9-cm, 12 volt fan (available from
Supermicro). After the new fan has been installed, reassemble the fan
housing. To put it back in the chassis, firdst insert the bottom fan
housing tab into its hole, then swing the top of the fan toward the
chassis, pushing down on the top fan housing tab to to insert it into the
corresponding hole in the chassis. You should hear it click into place
when fully inserted. Finish by plugging the fan cable back into the same
power connector you removed it from. Check that the fan is working
properly and that the LEDs on the control panel circuit board (Figure 6-2)
and the control panel have turned off. Finish by replacing the top panel
of the chassis.

SCSI Drive Installation

1. Mounting a SCSI drive in a drive carrier:

The SCSI drives are mounted in drive carriers to simplify their installation
and removal from the chassis. These carriers also help promote proper
airflow for the SCSI drive bays. For this reason, even empty carriers
without SCSI drives installed must remain in the chassis. To add a new
SCSI drive, install a drive into the carrier with the printed circuit board
side toward the carrier so that the mounting holes align with those in the
carrier. Secure the drive to the carrier with four screws, as shown in
Figure 6-4.

Figure 6-4. Mounting a SCSI Drive in a Carrier

!

Important: Regardless of how many SCSI hard drives
are installed, both SCSI drive carriers must remain in
the drive bays for proper airflow.

Use caution when working around the SCSI backplane.
Do not touch the backplane with any metal objects
and make sure no ribbon cables touch the backplane
or obstruct the holes, which aid in proper airflow.

2. Installing/removing hot-swap SCSI drives:

Four SCSI drive bays are located in the front of the chassis, making them
easily accesible to install and remove. The SCSI drives can be removed
and installed without powering down the system (hot-swap). To remove,
first push the release button located beside the drive LEDs, then swing
the burgundy colored handle fully out and use it to pull the unit straight
out (see Figure 6-5). Note: Your Operating System must have RAID

support to enable the hot-plug capability of the SCSI drives.

!

Important: Regardless of how many SCSI hard drives
are installed, all 4 SCSI drive carriers must remain in
the drive bays to maintain proper airflow.

Chapter 6: Advanced Chassis Setup

SCSI Power Cables

SCSI power cables should be routed in such a way that they do not block
the airflow through the chassis. There is a 4-pin connector for the power
cables. Connect the connector to the SCA SCSI backplane as noted in Step
3 ("Configuring the hot-plug SCSI drives").

SCA Backplane

The SCSI drives plug into a SAF-TE compliant SCA backplane that provide
power and bus termination. A RAID controller can be used with the SCA
backplane to provide data security. The operating system you use must
have RAID support to enable the hot-swap capability of the SCSI drives. All
the jumpers on the SCA backplane are preset and should not be changed.
See Figure 6-6.

CD-ROM and Floppy Drive Installation

The top cover of the chassis must be opened to gain full access to the CD­ROM and floppy drive bays. The CD-ROM drive must have a "slim" profile to
fit into the 8042-8/8042-6.

First, release the two retention screws that secure the unit to the rack.
Next, release the two screws that secure the top cover to the chassis.
Grasp the two handles on either side and pull the unit straight out. There
are two square recesses in the top cover to help you push the cover
away from you until it stops. You can then remove the top cover from
the chassis. You must power down the system before installing or
removing floppy or IDE drives.

Drives mount on rails and should "click" into place to be correctly and
fully installed in their bays. You should keep the metal shields in place on
any unused drives to reduce EMI and noise and to facilitate the airflow
inside the chassis.

• The floppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single floppy disk drive ribbon cable has 34 wires and two connectors to
provide for two floppy disk drives. The connector with twisted wires always
connects to drive A, and the connector that does not have twisted wires
always connects to drive B.

6-5 Power Supply Modules

The SC862 has a set of 700W Triple Redundant Power Supply which
consists of three individual Power Supply Modules (SP352-TP p/n PWS­026 or p/n PWS-026B for black bezels.) All three modules provide a
continuous 700 watts of power to the system. If any one fails, the
remaining two will automatically take up the load to keep the system
running. All three are hot-pluggable, allowing you to replace a failed
module without powering down the system. These power supply
modules also have an auto-switching capability, which enables them to
automatically sense and operate at any voltage level between 100 and
225 input volts.

Power Supply Failure

If any one of the three power modules fails, the remianing two modules
will assume the full load and enable the system to continue operating
without interruption. An audible alarm will notify you of a power module
failure, which you can disable by pressing the alarm switch on the
chassis control panel. The PWR Fail LED will also illuminate and remain
on until the failed module has been replaced.

Replacing Power Modules

1. Identifying the failed power module:

Inspect the power modules mounted in the front of the chassis. The
module with the illuminated red LED has failed and should be replaced as
soon as possible. If the LED is neither red or green, check to make sure
all three power cables are all fully plugged into the back of the chassis.
If they are, the power module is probably bad.

2. Removing a hot-plug power module: (See Figure 6-7)

You do not need to power down the system to replace a failed power
module. To remove a failed module, push the locking tab on the failed
module up, then grasp the handle and pull the module completely out.
You don't need to unplug the power cable from the back of the chassis.

3. Installing a new hot-plug power unit:

Replace the failed unit with another unit of the same model: SP352-TP
(p/n PWS-026). Gently but firmly push the new unit all the way into the
open bay. Secure it by pushing the locking tab downward. The green
LED on the power supply unit should illuminate to show that it has power
and is operational.

BIOS

7-1 Introduction

This chapter describes the AMIBIOS for the P4QH8/P4QH6. The AMI ROM BIOS
is stored in a Flash EEPROM and can be easily upgraded using a floppy disk­based program.

Note: Due to periodic changes to BIOS, some settings may have been added or
deleted and might not yet be recorded in this manual. Refer to the Manual
Download area of our web site for any changes to BIOS that are not reflected in
this manual.

System BIOS

The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®, and
PS/2® compatible computers. The BIOS ROM stores the system parameters,
such as amount of memory, type of disk drives and video displays, etc. BIOS
ROM requires very little power. When the computer is turned off, a back-up
battery provides power to the BIOS ROM, enabling it to retain the system param­eters. Each time the computer is powered-on, the computer is then configured
with the values stored in the BIOS ROM by the system BIOS, which gains control
when the computer is powered on.

How To Change the Configuration Data

The configuration data that determines the system parameters may be changed
by entering the BIOS Setup utility. This Setup utility can be accessed by press­ing <Del> at the appropriate time during system boot.

Starting the Setup Utility

Normally, the only visible POST (Power On Self Test) routine is the memory test.
As the memory is being tested, press the <Delete> key to enter the main menu
of the BIOS Setup utility. From the main menu, you can access the other setup
screens, such as the Chipset and Power menus. Section 4-3 gives detailed
descriptions of each parameter setting in the Setup utility.

An AMIBIOS identification string is displayed at the left bottom corner of the
screen, below the copyright message.
