Canterwood ES (E7210)

Intel’s Canterwood Chipset (875P) and Canterwood ES (E7210) contains the
following main components: Canterwood Memory Controller Hub (MCH) and
the I/O Controller Hub (6300ESB-Hance Rapids ICH). These two compo­nents are interconnected via Hub Interface.

Memory Controller Hub (MCH)

The Canterwood Memory Controller Hub (MCH) is designed to support Intel
PGA 478-pin Processors. The function of the 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 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.

Chapter 1: Introduction

1-3 PC Health Monitoring

This section describes the PC health monitoring features of the SUPER
P4SCT/P4SCT+/P4SCT+II. 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,

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 Supermicro's Monitoring Software-Supero
Doctor.

++

+5V, +5V standby, Vbat and

++

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 P4SCT/P4SCT+/P4SCT+II 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.

±±

±12V

±±

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 Supermicro. This feature can prevent viruses from in­fecting the BIOS area and destroying valuable data.

Auto-Switching Voltage Regulator for the CPU Core

The 4-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.

and power settings.

Microsoft OnNow

The OnNow design initiative is a comprehensive, system-wide approach to
system and device power control. OnNow is a term for a PC that is always
on but appears to be off and responds immediately to user or other re­quests.

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 depresses the power button, the
system will enter a SoftOff state. The monitor will be suspended and the
hard drive will spin down. Depressing 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
depress 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.

Chapter 1: Introduction

Wake-On-LAN (WOR) Header

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 1.0 GHz and faster.

The SUPER P4SCT/P4SCT+/P4SCT+II 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 1.0 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).

(*Warning: Do not use a wrong type of onboard CMOS battery or
install the CMOS battery upside down to avoid possible explo­sion.)

1-13

SUPER P4SCT/P4SCT+/P4SCT+II User’s Manual

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 1.0 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.

(*Warning: Do not use a wrong type of on board CMOS battery or
install the battery upside down to avoid possible explosion.)

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.

!

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.

Installation of the Processor and Heatsink

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

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 Supermicro or Intel certified heatsink and fan.

direct pressure on the label area of the fan.

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.)

Bracket in
position

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.

2-2

5. Lift the lever on the CPU socket.

6. Install the CPU in the socket. Make sure that
Pin 1 of the CPU is seated on Pin 1 of the socket
(both corners are marked with a triangle).

7. Press the lever down until

you hear it *click* into the
locked position.

2-3 Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of
chassis. Make sure the location 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 the metal
standoffs click in or are screwed in tightly. Then use a screwdriver to
secure the motherboard onto the motherboard tray. (*Note: Some compo­nents are very close to the mounting holes. All precautionary measures
shall be taken to prevent damage done to these components when installing
the motherboard into the chassis.)

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.

Chapter 2: Installation

Support

The P4SCT/P4SCT+/P4SCT+II supports Dual channel, ECC/non-ECC,
unbuffered DDR-400/333/266 SDRAM.

(Populate DIMM0A,DIMM1A and/
or DIMM0B, DIMM1B with memory modules of the same size/same type
will result in the dual channel, two-way interleaved memory which is
faster than the single channel memory.

(*Note: The Canterwood chip supports non-ECC or ECC memory. If ECC
memory is installed, the ECC bits need to be initialized via BIOS before normal
operation. For a 4 GB-Memory and 2.4-GHz P4 system, it will take about 65
seconds for all the ECC bits to be initialized before any video displays. Since
ECC initialization takes time, the Watch Dog Timer Select needs to be set to a
time longer than what the ECC initialization will take.)
