1-2 Chipset Overview (Intel's E7210 Canterwood
Chipset)

The E7210 Canterwood Chipset contains the following main components:
the E7210 Canterwood Memory Controller Hub (MCH) and the I/O Controller
Hub 5(ICH5R). These two components are interconnected via Hub Inter­face.

Memory Controller Hub (MCH)

The E7210 Canterwood Memory Controller Hub (MCH) is designed to sup­port Intel PGA 478-pin Processors. The function of the E7210 Canterwood
MCH is to arbitrate the flow of data transfer between system bus (FSB),
system memory, and Hub Interface. The Canterwood MCH supports 800
MHz FSB, 400/333 Memory Interface, 533 MHz FSB, 333/266 Memory Inter­face, and 400 MHz FSB 266 MHz Memory Interface.

System Memory Interface

The E7210 Canterwood Memory Controller (MCH) supports two 64-bit wide
DDR data channels with bandwidth up to 6.4 GB/s (DDR400) in dual channel
mode. It supports 128-Mb, 256-Mb,512-Mb, x8, X16 DDR. Maximum system
memory supports up to 4.0 GB for Dual-Channel. ECC/Non ECC unbuffered
DDR DIMMs are supported, but it does not support registered, mixed-mode
DIMMs.

Intel ICH5R System Features

The I/O Controller Hub provides the I/O subsystem with access to the rest
of the system. It supports 2-channel Ultra ATA/100 Bus Master IDE Control­ler, two Serial ATA (SATA) Host Controllers, SMBus 2.0 Controller, LPC/
Flash BIOS Interface, PCI 2.3 Interface, and Integrated System Management
Controller.

SUPER P4SCA/P4SCE User’s Manual

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
P4SCA/P4SCE. The motherboard has an onboard System Hardware Monitor
chip that supports PC health monitoring.

Eight Onboard Voltage Monitors for the CPU Core, +3.3V,
+3.3V standby,

++

++

+5V, +5V standby, Vbat and

±±

±±

±12V

The onboard voltage monitor will scan these voltages continuously. Once a
voltage becomes unstable, it will give a warning or send an error message
to the screen, using Super Micro's Monitoring Software-Super O Doctor.

Fan Status Monitor with Firmware/Software On/Off Control

The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin fans are controlled by the power management functions.

Environmental Temperature Control

The P4SCA/P4SCE has a CPU "thermal trip" feature. A thermal control sen­sor monitors the CPU temperature in real time and will send a signal to shut
down the system whenever the CPU temperature exceeds a certain thresh­old. This works to protect the CPU from being damaged by overheating.

CPU Overheat LED and Control

This feature is available when the user enables the CPU overheat warning
function in the BIOS. This allows the user to define an overheat tempera­ture. When this temperature is exceeded, the CPU thermal trip feature will
activate and shut down the system.

Hardware BIOS Virus Protection

The system BIOS is protected by hardware so that no virus can infect the
BIOS area. The user can only change the BIOS content through the flash
utility provided by Super Micro. This feature can prevent viruses from
infecting the BIOS area and destroying valuable data.

Chapter 1: Introduction

1-15

Auto-Switching Voltage Regulator for the CPU Core

The 3-phase-switching voltage regulator for the CPU core can support up to
60A current and auto-sense voltage IDs ranging from 1.1V to 1.85V. This
will allow the regulator to run cooler and thus make the system more stable.

1-4 Power Configuration Settings

This section describes features of your motherboard that deal with power
and power settings.

Slow Blinking LED for Suspend-State Indicator

When the CPU goes into a suspend state, the chassis power LED will start
blinking to indicate that the CPU is in suspend mode. When the user presses
any key, the CPU will wake-up and the LED will automatically stop blinking
and remain on.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, it keyboard will
function like a normal keyboard during system boot-up.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function as a
system suspend button. When the user presses the power button, the
system will enter a SoftOff state. The monitor will be suspended and the
hard drive will spin down. Pressing the power button again will cause the
whole system to wake-up. During the SoftOff state, the ATX power supply
provides power to keep the required circuitry in the system alive. In case
the system malfunctions and you want to turn off the power, just press and
hold the power button for 4 seconds. The power will turn off and no
power will be provided to the motherboard.

Wake-On-Ring (WOR) Header

Wake-up events can be triggered by a device such as the external modem
ringing when the system is in the SoftOff state. Note that external modem
ring-on can only be used with an ATX 2.01 (or above) compliant power
supply.

1-16

SUPER P4SCA/P4SCE User’s Manual

Wake-On-LAN (WOL)

Wake-On-LAN is defined as the ability of a management application to re­motely power up a computer that is powered off. Remote PC setup, up­dates and asset tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The
motherboards have a 3-pin header (WOL) to connect to the 3-pin header on
a Network Interface Card (NIC) that has WOL capability. Note that Wake­On-Lan can only be used with an ATX 2.01 (or above) compliant power
supply.

1-5 Power Supply

As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors that
have high CPU clock rates of 1 GHz and faster.

The SUPER P4SCA/P4SCE accommodates 12V ATX power supplies. Al­though most power supplies generally meet the specifications required by
the CPU, some are inadequate. You power supply must supply 1 amp of 5V
standby voltage.

It is strongly recommended that you use a high quality power supply that
meets 12V ATX power supply Specification 1.1 or above. Additionally, in
areas where noisy power transmission is present, you may choose to in­stall a line filter to shield the computer from noise. It is recommended that
you also install a power surge protector to help avoid problems caused by
power surges.

It also provides two high-speed, 16550 compatible serial communication
ports (UARTs), one of which supports serial infrared communication. Each
UART includes a 16-byte send/receive FIFO, a programmable baud rate
generator, complete modem control capability and a processor interrupt sys­tem. Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps
as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s,
which support higher speed modems.

The Super I/O provides functions that comply with ACPI (Advanced Con­figuration and Power Interface), which includes support of legacy and ACPI
power management through a SMI or SCI function pin. It also features auto
power management to reduce power consumption.

The IRQs, DMAs and I/O space resources of the Super I/O can be flexibly
adjusted to meet ISA PnP requirements, which support ACPI and APM (Ad­vanced Power Management).

1-6 Super I/O

The disk drive adapter functions of the Super I/O chip include a floppy disk
drive controller that is compatible with industry standard 82077/765, a data
separator, write pre-compensation circuitry, decode logic, data rate selec­tion, a clock generator, drive interface control logic and interrupt and DMA
logic. The wide range of functions integrated onto the Super I/O greatly
reduces the number of components required for interfacing with floppy disk
drives. The Super I/O supports four 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M
disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s.

2-1 Static-Sensitive Devices

Electric Static Discharge (ESD) can damage electronic components. To
prevent damage to your system board, it is important to handle it very
carefully. The following measures are generally sufficient to protect your
equipment from ESD.

Precautions

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

• Touch a grounded metal object before removing the board from the anti­static bag.

• Handle the 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 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 motherboard.

Unpacking

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

Installation Procedures

Follow the procedures as listed below for full installation of the mother­board into a chassis:

1. Install the processor and the heatsink to the motherboard.

2. Install the motherboard in the chassis.

3. Install the memory and add-on cards.

4. Finally, connect the cables and install the drivers.

2-2

SUPER P4SCA/P4SCE User's Manual

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

2-2 Processor and Heatsink Fan Installation

When handling the processor package, avoid placing
direct pressure on the label area of the fan.

Installation of the Processor and Heatsink

1. Locate the following components, which are included in the shipping
package.

Bracket (1)

2. Insert the white pegs into the black an­chors. Do not force the white pegs all the
way in - about 1/3 of the white pegs should
be inside the black anchors. (These are for
chassis that do not have four CPU retention
holes.)

3. Place a retention bracket in the proper position
and secure it by pressing two pegs into the reten­tion holes until you hear a *click*. The clicking
sound indicates that the peg is locked and secured.

4. Secure the other retention bracket into position by repeating Step 3.

If you buy a boxed Intel Pentium 4 478 processor, it should include a
heatsink, fan and retention mechanism. If you buy a processor separately,
use only a Super Micro or Intel certified heatsink and fan.

2-4 Installing DDR Memory

CAUTION

Exercise extreme care when installing or removing memory

modules to prevent any possible damage.

Memory Module Installation (See Figure 2-2)

1. Insert each DDR memory module vertically into its slot. Pay attention to
the notch along the bottom of the module to prevent inserting the mod­ule incorrectly. (See support information below.)

2. Gently press down on the memory module until it snaps into place.

2-3 Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of
chassis. Make sure that the locations of all the mounting holes for both the
motherboard and the chassis match. Although a chassis may have both
plastic and metal mounting fasteners, metal ones are highly recommended
because they ground the motherboard to the chassis. Make sure that the
metal standoffs click in or are screwed in tightly. Then, use a screwdriver
to secure the motherboard onto the motherboard tray.
