1-3 Server Chassis Features
The SC743S1-R760 is a scaleable server platform that may be deployed either
in a tower or a 4U rackmount confi guration. The following is a general outline of
the main features of the SC743S1-R760 chassis.
System Power
The SC743S1-R760 features a triple redundant 760W power supply that consists
of three separate power supply modules. These modules all share the load and run
continuously. If any of the three fail, the remaining two pick up the load and keep
the system running without interruption. A failed power supply module will illuminate
the power fail LED. The power supply modules are all hot-swappable, so you don’t
have to power down the system to replace a module.
SCSI Subsystem
The SCSI subsystem supports eight 80-pin SCA Ultra320 SCSI hard drives. (Any
standard 1" drives are supported. SCA = Single Connection Attachment.) The SCSI
drives are connected to an SCA backplane that provides power, bus termination and
confi guration settings. The SCSI drives are also hot-swap units
Note: The operating system you use must have RAID support to enable the hot-
swap capability of the SCSI drives.
Control Panel
The chassis' control panel provides you with system monitoring and control. LEDs
indicate system power, HDD activity, network activity, system overheat/fan fail and
power supply failure. A main power button and a system reset button are also
included..
I/O Backplane
The SC743S1-R760 is an Extended ATX form factor chassis that can be used either
as a tower or as a 4U rackopunrt unit. The I/O backplane provides six motherboard
expansion slots, one COM port, a VGA port, two USB ports, PS/2 mouse and key-
board ports, a parallel port and two gigabit Ethernet ports.

Chapter 1: Introduction
Cooling System
The The SC743S1-R760 chassis has an innovative cooling design that includes
four 8-cm hot-plug system cooling fans located in the middle section of the chas-
sis and two 8-cm hot-plug rear exhaust fans. Each power supply module also
includes a cooling fan. An air shroud, which directs the airfl ow to the areas of
highest heat build-up, is also included. All chassis and power supply fans operate
continuously.
A setting in BIOS (see p. 7-18) is used to control the system fan speed. This setting
uses voltage control to allow fans to run at different speeds. [The recommended
setting is “4-pin (Server)”.]

Chapter 2
Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your AS 4020A-8R server 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 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 specifi c components.
The AS 4020A-8R may be employed either as a tower or mounted in a rack as a
4U rackmount chassis. If using it as a tower unit, please read the Server Precau-
tions in the next section and then skip ahead to Section 2-5.
2-2 Unpacking the System
You should inspect the box the system was shipped in and note if it was damaged
in any way. If the server itself shows damage you should fi le a damage claim with
the carrier who delivered it.
Decide on a suitable location for the AS 4020A-8R. It should be situated in a clean,
dust-free area that is well ventilated. Avoid areas where heat, electrical noise and
electromagnetic fi elds are generated. You will also need it placed near a grounded
power outlet. Be sure to read the Rack and Server Precautions in the next sec-
tion.
2-3 Preparing for Setup
The box the system was shipped in may include two sets of rail assemblies, two
rail mounting brackets and mounting screws needed for installing the system into a
rack (optional kit). 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.
2-1
A+ Server 4020A-8R User's Manual
Choosing a Setup Location
- Leave enough clearance in front of the system to enable you to open the front
door completely (~25 inches).
- Leave approximately 30 inches of clearance in the back of the system to allow for
suffi cient airfl ow and ease in servicing.
- This product is for installation in a Restricted Access Location only (dedicated
equipment rooms, service closets, etc.)
!
Warnings and Precautions!
!
Rack Precautions
- Ensure that the leveling jacks on the bottom of the rack are fully extended to the
fl oor 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 simul-
taneously 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 fi rst, and then
work up.
- Use a regulating uninterruptible power supply (UPS) to protect the server from
power surges, 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.
2-2
Chapter 2: Server Installation
Rack Mounting Considerations
Ambient Operating Temperature
If installed in a closed or multi-unit rack assembly, the ambient operating tempera-
ture 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 tempera-
ture (Tmra).
Reduced Airfl ow
Equipment should be mounted into a rack so that the amount of airfl ow required
for safe operation is not compromised.
Mechanical Loading
Equipment should be mounted into a rack so that a hazardous condition does not
arise due to uneven mechanical loading.
Circuit Overloading
Consideration should be given to the connection of the equipment to the power
supply circuitry and the effect that any possible overloading of circuits might have
on overcurrent protection and power supply wiring. Appropriate consideration of
equipment nameplate ratings should be used when addressing this concern.
Reliable Ground
A reliable ground must be maintained at all times. To ensure this, the rack itself
should be grounded. Particular attention should be given to power supply connec-
tions other than the direct connections to the branch circuit (i.e. the use of power
strips, etc.).
2-3
A+ Server 4020A-8R User's Manual
2-4 Installing the System into a Rack
This section provides information on installing the system into a rack unit. Rack
installation requires the use of the optional rackmount kit [CSE-PT26(B)]. If the
system has already been mounted into a rack or if you are using it as a tower, 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 server into a rack with the rack rails provided in the
rackmount kit. You should also refer to the installation instructions that came with
the rack unit you are using.
Identifying the Sections of the Rack Rails
The optional rackmount kit (CSE-PT26 or CSE-PT26B - black) includes two rack
rail assemblies. Each of these assemblies consist of three sections: an inner fi xed
chassis rail that secures to the chassis, an outer rack rail that secures directly to
the rack itself and two rail brackets, which also attack to the rack (see Figure 2-1.)
The inner and outer rails must be detached from each other to install.
To remove the inner chassis rail, pull it 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. Do this for
both assemblies (one for each side).

Chapter 2: Server Installation
Installing the Chassis Rails
You will need to remove the top cover and the feet to add rack rails to the chassis.
First, remove the top and right covers (top and left covers when standing as a tower
chassis) by fi rst removing the screws that secure them to the chassis. Depress
the button on the top (side if tower) of the chassis to release the cover and then
pull the cover off. Then unscrew the four feet and remove them from the chassis
(see Figure 2-2).
You can now attach rack rails to the top and bottom (now the sides) of the chassis.
First add the rack handles. Then position the inner chassis rail sections you just
removed along the side of the chassis making sure the screw holes line up. Note
that these two rails are left/right specifi c. Screw the rail securely to the side of the
chassis (see Figure 2-3). Repeat this procedure for the other rail on the other side
of the chassis. You will also need to attach the rail brackets when installing into a
telco rack.
Locking Tabs: As mentioned, the chassis rails have a locking tab, which serves
two functions. The fi rst is to lock the server into place when installed and pushed
fully into the rack, which is its normal position. Secondly, 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. Preparing to Install the Chassis Rails

Figure 2-3. Installing the Rails to the Chassis
Installing the Rack Rails
Determine where you want to place the AS 4020A-8R in the rack. (See Rack and
Server Precautions in Section 2-3.) Position the fi xed 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 sure both
are at the exact same height and with the rail guides facing inward.
2-6
Chapter 2: Server Installation
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. You should have two brackets in the rack
mount kit. Install these fi rst keeping in mind that they are left/right specifi c (marked
with "L" and "R"). Then, line 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).
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 (see Figure 2-4).

2-5 Checking the Serverboard Setup
After setting up the the system, 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 system (see Figure 2-5)
[If rack mounted, fi rst release the retention screws that secure the unit to the rack.
Grasp the two handles on either side and pull the unit straight out until it locks (you
will hear a "click").] There are two screws that secure the cover to the chassis -
remove these fi rst. Depress the button on the top (side if tower) of the chassis to
release the cover. You can then lift the cover from the chassis to gain full access
to the inside of the server.
2. Check the CPUs (processors)
You may have one or two processors already installed into the serverboard. Each
processor should have its own heatsink attached. See Chapter 5 for instructions
on processor installation.
3. Check the system memory
Your server may have come with system memory already installed. Make sure all
DIMMs are fully seated in their slots. For details on adding system memory, refer
to Chapter 5.
4. Installing add-on cards
If desired, you can install add-on cards to the system. See Chapter 5 for details
on installing PCI add-on cards.
5. Check all cable connections and airfl ow
Make sure all power and data cables are properly connected and not blocking the
chassis airfl ow. 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 SCSI drives
and SCA 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,
IDE hard drives and fl oppy drives, you will need to remove the top/left chassis cover.

Chapter 2: Server Installation
Figure 2-5. Accessing the Inside of the System
(Rack Confi guration shown)
The SCSI disk drives can be installed and removed from the front of the chassis
without removing any chassis covers.
2. Installing components into the 5.25" drive bays
To install components into the 5.25" drive bays, you must fi rst remove the top/left
chassis cover as described in the previous section. Refer to Chapter 6 for de-
tails.
3. Installing CD-ROM and fl oppy disk drives
Refer to Chapter 6 if you need to reinstall a CD-ROM and/or fl oppy disk drive to
the system.
4. Check the SCSI disk drives
Depending upon your system's confi guration, your system may have one or more
drives already installed. If you need to install SCSI drives, please refer to Chapter
6.
5. Check the airfl ow
Airfl ow is provided by four hot-swap 8-cm chassis fans working in conjunction with
an air shroud. Two 8-cm exhaust fans are also mounted at the rear of the chassis.
The system component layout was carefully designed to promote suffi cient airfl ow
through the chassis. Also note that all power and data cables have been routed in
such a way that they do not block the airfl ow generated by the fans. Keep this in
mind when you reroute them after working on the system.

6. Supplying power to the system
The last thing you must do is to provide input power to the system. Plug the power
cord from the power supply unit into a high-quality power strip that offers protec-
tion from electrical noise and power surges. It is recommended that you use an
uninterruptible power supply (UPS). Finally, depress the power on button on the
front of the chassis.

System Interface
3-1 Overview
The control panel on the AS 4020A-8R has several LEDs and two buttons. There
are also two LEDs on each SCSI drive carrier and the Ethernet ports. These LEDs
keep you constantly informed of the overall status of the system and the activity
and health of specifi c components.
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 power on/off button and a reset button.
POWER: This is the main power button, which is used to apply or turn off
the main system power. Turning off system power with this button removes the
main power but keeps standby power supplied to the system.
RESET:
Use the reset button to reboot the system.

3-3 Control Panel LEDs
The control panel located on the front of the SC743S1-R760 chassis has six LEDs
that 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:
LED should normally be on when the system is operating.
HDD: Indicates IDE channel activity. On the SC743S1-R760, this LED
indicates SCSI drive activity when fl ashing.
NIC1:
Indicates power is being supplied to the system's power supply. This
1
Indicates network activity on LAN1 when fl ashing.
2
NIC2: Indicates network activity on LAN2 when fl ashing.
Overheat/Fan Fail: When this LED fl ashes, it indicates a fan failure. When
on continuously it indicates an overheat condition, which may be caused by cables
obstructing the airfl ow in the system or the ambient room temperature being too
warm. Check the routing of the cables and make sure all fans are present and
operating normally. You should also check to make sure that the chassis covers
are installed. Finally, verify that the heatsinks are installed properly (see Chapter
5). This LED will remain fl ashing or on as long as the indicated condition exists.

Chapter 3: System Interface
Power Fail: Indicates a power supply module has failed. This should be
accompanied by an audible alarm. A backup power supply module will take the
load and keep the system running but the failed module will need to be replaced.
Refer to Chapter 6 for details on replacing the power supply. This LED should be
off when the system is operating normally.
3-4 SCSI Drive 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: A SAF-TE compliant backplane is needed to activate the red LEDs,
which indicate a drive failure. Please refer to Chapter 6 for instructions on replacing
failed SCSI drives.
3-5 LAN (Ethernet) Port LEDs
The LAN Ethernet ports each have two LEDs. The yellow (left) LED indicates activity
while the other (right) LED may be green, orange or off to indicate the speed of the
connection. See the tables below for the functions associated with these LEDs.
