1-3 Server Chassis Features
The SC813T+-500 is our third-generation 1U chassis and features four hot-swap
Serial ATA drive bays, a slim CD-ROM drive, a slim 3.5" fl oppy drive and a revo-
lutionary cooling design that can keep today's most powerful processors running
well below their temperature thresholds. The following is a general outline of the
main features of the SC813T+-500 chassis.
System Power
The SC813T+-500 chassis includes a single 500W cold-swap power supply.
Serial ATA Subsystem
For the 1020A-T, the SC813T+-500 chassis was designed to support four Serial
ATA hard drives, which are hot-swappable units. RAID 0 and RAID 1 levels are
supported.
Note: The system's operating system must have RAID support to enable the hot-
swap capability of the Serial ATA drives.
Control Panel
The control panel provides important system monitoring and control information.
LEDs indicate power on, network activity, hard disk drive activity and system over-
heat conditions. Also present are main power and system reset buttons.
I/O Backplane
The SC813T+-500 is a 1U rackmount chassis. Its I/O backplane provides one
full-height, half-length and one low profi le slot for PCI add-on cards, one COM port

ports and two Ethernet (LAN) ports. (See Figure 1-2.)
1-4
Chapter 1: Introduction
Cooling System
The SC813T+-500 chassis' revolutionary cooling design has been optimized to
provide suffi cient cooling for dual processor confi gurations. The chassis includes
four counter-rotating 4-cm fans located in the middle of the chassis. In the event
of a fan failure, the ambient air temperature inside the chassis will rise and activate
an overheat LED (fan speed is controlled by the system temperature).
A fan speed control setting in BIOS allows chassis fan speed to be determined by
system temperature [recommended setting is 3-pin (Server)].

Server Installation
2-1 Overview
This chapter provides a quick setup checklist to get your A+ 1020A-T system 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 1020A-T 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.
2-2 Unpacking the System
You should inspect the box the 1020A-T 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 rack unit that will hold the 1020A-T. 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. Read the Rack and Server Precautions in
the next section.
2-3 Preparing for Setup
The box the 1020A-T 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.
2-1
A+Server 1020A-T User's 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
suffi cient airfl ow and ease in servicing.
- This product is for installation only in a Restricted Access Location (dedicated
equipment rooms, service closets and the like).
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 Serial ATA drives and power supply units to cool before touch-
ing 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
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).
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 consid-
eration 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 con-
nections other than the direct connections to the branch circuit (i.e. the use of
power strips, etc.).
2-3
A+Server 1020A-T User's Manual
2-4 Installing the System into a Rack
This section provides information on installing the 1020A-T into a rack unit with the
rack rails provided. If the 1020A-T 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. You should also refer
to the installation instructions that came with the rack unit you are using.
Identifying the Sections of the Rails
You should have received a rack mounting kit with the 1020A-T. The kit includes
two sets of chassis rails (four pieces total, two of which are already installed on
the chassis) and two sets of rack rails (four pieces total). Figure 2-1 displays the
two right-side chassis rails and the two right-side rack rails. Note that two of the
four chassis rails (Chassis Rail 1) are already attached to the chassis.
Installing the Rack Rails
Begin by joining one set of rack rails corresponding to either the left or the right side
of the rack. Do this by aligning the studs of one rail with the holes of the other rail.
Push the studs into the grooved holes and then push the rail to slide the studs to
the end of the groove. Repeat this with the rack rails used for the other side.
Next, determine where you want to place the 1020A-T in the rack. (See Rack
and Server Precautions in Section 2-3.) Position the assembled rack rails at the
desired location in 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.
Locking Tabs: Both of the two chassis rails on each side have a locking tab (four
total), 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 operating position.
Secondly, these tabs also lock the server in place when extended from the rack.
This prevents the server from coming completely out of the rack when you pull it
out for servicing. The two sets of locking tabs mean there are two locked positions
when the chassis is extended from the rack, allowing easy access when servicing
the system. Note that on one side, you push the locking tab up to release it and
on the other side you push it down to release.
2-4
Chapter 2: Server Installation
Installing the Chassis Rails
Two of the chassis rails (Chassis Rail 1) should have already been preattached
- one to each side of the chassis. Attach the second set of chassis rails (Chassis
Rail 2) directly to the chassis with the screws provided. Chassis Rail 2 should
be positioned just behind Chassis Rail 1 (see Figure 2-2). Do this for both sides
of the chassis.
Figure 2-1. Identifying the Sections of the Rails
Figure 2-2. Installing Chassis Rails
2-5
A+Server 1020A-T User's Manual
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 lock-
ing tabs when inserting). See Figure 2-3.
When the server has been pushed completely into the rack, you should hear the
locking tabs "click". Finish by inserting and tightening the thumb screws that hold
the front of the server to the rack.
Figure 2-3. Installing the Server into a Rack

Chapter 2: Server Installation
Installing the Server into a Telco Rack
If you are installing the 1020A-T into a Telco type rack, follow the directions given
on the previous pages for rack installation. The only difference in the installation
procedure will be the positioning of the rack brackets to the rack. They should be
spaced apart just enough to accommodate the width of the telco rack.

A+Server 1020A-T User's Manual
2-5 Checking the Serverboard Setup
After you install the A+ 1020A-T 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 1020A-T (see Figure 2-5)
First, 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"). Next, depress the two buttons on the top of the chassis to release
the top cover. There is a large rectangular recess in the middle front of 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 to gain full access to the inside of the server.
2. Check the CPUs (processors)
You should have one or two processors already installed into the serverboard.
Each processor needs its own heatsink. See Chapter 5 for instructions on pro-
cessor and heatsink installation.
3. CPU Speed
The CPU speed should automatically be detected so you will not need to change
any jumpers or settings in the BIOS Setup utility.
4. Check the system memory
Your 1020A-T server system 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.
5. 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.
6. 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 Serial ATA drives
have been properly installed and all connections have been made.
1. Accessing the drive bays
All drives are accessable from the front of the server. For servicing the CD-ROM
and fl oppy drives, you will need to remove the top chassis cover. The Serial ATA
disk drives can be installed and removed from the front of the chassis without
removing the top chassis cover or powering down the system.
2. CD-ROM and fl oppy disk drives
A slim CD-ROM and a fl oppy drive should be preinstalled in your server. Refer
to Chapter 6 if you need to reinstall a CD-ROM and/or fl oppy disk drive to the
system.
3. Check the SATA disk drives
Depending upon your system's confi guration, your system may have one or
more drives already installed. If you need to install Serial ATA drives, please
refer to Chapter 6.

4. Check the airfl ow
Airfl ow is provided by four sets of counter-rotating 4-cm fans. The system com-
ponent layout was carefully designed to direct the airfl ow to the components that
generate the most heat. 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.
5. Supplying power to the system
The last thing you must do is to provide power to the system. Plug the power
cord from the power supply module into a high-quality power strip that offers
protection from electrical noise and power surges. It is recommended that you
use an uninterruptible power supply (UPS). Finish by depressing the power
button on the front of the chassis to start the system.

3-1 Overview
There are several LEDs on the control panel as well as others on the Serial ATA
drive carriers to keep you constantly informed of the overall status of the system
as well as the activity and health of specifi c components. There are also two but-
tons on the chassis control panel and an on/off switch on the power supply. This
chapter explains the meanings of all LED indicators and the appropriate response
you may need to take.
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:
Power: The main power switch 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.
Use the reset switch to reboot the system.

3-3 Control Panel LEDs
The control panel located on the front of th SC813T+-500 chassis has fi ve 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.
Overheat/Fan Fail: When this LED fl ashes it indicates a fan failure. When
on continuously (on and not fl ashing) 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 overheat condition exists.

HDD: Indicates IDE channel activity. On the 1020A-T this light indicates
SATA and/or CD-ROM drive activity when fl ashing.
Power: Indicates power is being supplied to the system's power supply
units. This LED should normally be illuminated when the system is operating.
3-4 Serial ATA Drive Carrier LED
Each Serial ATA drive carrier has a green LED. When illuminated, this green LED
(on the front of the Serial ATA drive carrier) indicates drive activity. A connec-
tion to the Serial ATA backplane enables this LED to blink on and off when that
particular drive is being accessed.
Note: The second LED on the SATA carriers is not used.
