USB
High-Speed USB 2.0 Support
✏
NOTES
Use a shielded cable that meets the requirements for a full-speed USB
device. Computer systems that have an unshielded cable attached to a USB
port might not meet FCC Class B requirements, even if no device or a lowspeed USB device is attached to the cable.
USB devices are limited to USB 1.1 transfer rates prior to operating system
and driver initialization.
The server board supports up to six USB 2.0 ports via the ICH5. Four ports are routed to the back
panel. One header, supporting up to two ports, is routed to the front panel. USB 2.0 ports are
backward compatible with USB 1.1 devices. USB 1.1 devices will function normally at USB 1.1
speeds.
USB 2.0 support requires both an operating system and drivers that fully support USB 2.0 transfer
rates. Disabling High-Speed USB in BIOS reverts all USB 2.0 ports to USB 1.1 operation. This
may be required to accommodate operating systems that do not support USB 2.0.
Legacy USB Support
Legacy USB support allows USB devices such as keyboard, mice, and hubs to be used even when
the operating system’s USB drivers are not available. Legacy USB support is used to access the
BIOS Setup program, and to install an operating system that supports USB. By default, Legacy
USB support is set to Enabled.
Four of the USB ports are implemented with stacked back panel connectors; the other two are
accessible via the front panel USB header. The S875WP1-E server board fully supports UHCI and
uses UHCI-compatible software drivers.
NOTE
✏
Computer systems that have an unshielded cable attached to a USB port may not
meet FCC Class B requirements, even if no device is attached to the cable. Use
s shielded cable that meets the requirements for full-speed devices.
Server Board Features 19
Legacy USB support operates as follows:
1. When the user applies power to the computer, legacy support is disabled.
2. POST begins.
3. Legacy USB support is enabled by the BIOS allowing the user to use a USB keyboard to enter
and configure the BIOS Setup program and the maintenance menu.
4. POST completes.
5. The operating system loads. While the operating system is loading, USB keyboard and mice
are recognized and may be used to configure the operating system. (Keyboard and mice are not
recognized during this period if Legacy USB support is set to Disabled in the BIOS Setup
program.)
6. After the operating system loads the USB drivers, all legacy and non-legacy USB devices are
recognized by the operating system, and Legacy USB support from the BIOS is no longer used.
To install an operating system that supports USB, verify that Legacy USB support in the BIOS
Setup program is set to Enabled and follow the operating system’s installation instructions.
NOTE
✏
Legacy USB support is for keyboard, mice, and hubs only. Other USB
devices are not supported in legacy mode.
PCI I/O Subsystem
The primary I/O bus for the server board S875WP1-E is PCI, with one independent PCI bus. The
PCI bus complies with the PCI Local Bus Specification, Rev 2.3. The PCI bus is directed through

Server Board Features 21
IDE Interfaces
The ICH5-R IDE controller has two independent bus-mastering IDE interfaces that can be
independently enabled. The interface handles the exchange of information between the processor
and peripheral devices like hard disks and CD-ROM drives. The IDE interfaces supports:
• Up to four IDE devices (such as hard drives)
• ATAPI devices (such as CD-ROM drives)
• Laser servo (LS-120) drives
• PIO Mode devices
• Ultra DMA-33: DMA protocol on IDE bus supporting host and target throttling and transfer
rates of up to 33 MB/sec.
• ATA-100/66: DMA protocol on IDE bus supporting host and target throttling and transfer
rates of up to 100 MB/sec. The ATA-100/66 protocol is similar to Ultra DMA and is device
driver compatible.
✏ NOTE
ATA-100/66 is a faster timing and requires a specialized cable to reduce
reflections, noise, and inductive coupling.
The IDE interfaces also support ATAPI devices (such as CD-ROM drives) and ATA devices using
the transfer modes.
The BIOS supports Logical Block Addressing (LBA) and Extended Cylinder Head Sector (ECHS)
translation modes. The drive reports the transfer rate and translation mode to the BIOS.
The S875WP1-E server board supports Laser Servo (LS-120) diskette technology through the IDE
interfaces. An LS-120 drive can be configured as a boot device by setting the BIOS Setup
program’s Boot menu to one of the following:
• ARMD-FDD (ATAPI removable media device – floppy disk drive)
• ARMD-HDD (ATAPI removable media device – hard disk drive)
SCSI Hard Drive Activity LED Connector
The SCSI hard drive activity LED connector is a 1 x 2-pin connector that allows an add-in
SCSI controller to use the same LED as the onboard IDE controller. For proper operation, this
connector should be wired to the LED output of the add-in SCSI controller. The LED indicates
when data is being read from, or written to, both the add-in SCSI controller and the IDE controller.
22 Intel Server Board S875WP1-E Product Guide
Network Interface Controller (NIC)
The server board S875WP1-E supports two Network Interface Controllers (NICs), one that runs at
10/100Mb and is based on the Intel 82562ET NIC and the other that runs at one gigabit and is
based on the Intel 82547EI NIC. When looking at the rear of the chassis, the gigabit NIC is at the
left (closest to the video port) and the 10/100Mb NIC is at the right. You can disable either or both
NICs through BIOS Setup.
The 82562ET is controlled by the ICH5-R and supports the following features:
• Integrated IEEE 802.3 10Base-T and 100Base-TX compatible PHY

Power Management
Power management is implemented at several levels, including:
• Software support through Advanced Configuration and Power Interface (ACPI)
• Hardware support:
— Suspend to RAM (Instantly Available PC technology)
— Power connectors
— Fan connectors
— Resume on Ring
— Wake from USB
— Wake from PS/2 keyboard/mouse
— PME# wakeup support
Software Support through ACPI
The Advance Configuration and Power Interface (ACPI)–aware operating system can place the
system into a state where the hard drives spin down, the system fans stop, and all processing is
halted. In this state, the power supply is still on and the processors still dissipate some power, so
the power supply fan and processor fans are still running.
Under ACPI, the operating system directs all system and device power state transitions. The
operating system puts devices in and out of low-power states based on user preferences and
knowledge of how devices are being used by applications. Devices that are not being used can be
turned off. The operating system uses information from applications and user settings to put the
system as a whole into a low-power state.
24 Intel Server Board S875WP1-E Product Guide
ACPI features include:
• Plug and Play (including bus and device enumeration)
• Power management control of individual devices, add-in boards (some add-in boards may
require an ACPI-aware driver), video displays, and hard disk drives
• Methods for achieving less than 15-watt system operation in the power-on/standby
sleeping state
• A soft-off feature that enables the operating system to power-off the computer
• Support for multiple wake-up events
• Support for a front panel power and sleep mode switch
The Server Board S875WP1-E supports sleep states S0, S1, S2, S3, S4, and S5. When the server
board is operating in ACPI mode, the operating system retains control of the system and the
operating system policy determines the entry methods and wake-up sources for each sleep state.
Sleep entry and wake-up event capabilities are provided by the hardware but are enabled by the
operating system. The following is a summary of the supported sleep states:
• S0: Normal running state.
• S1: Processor sleep state. No context will be lost in this state and the processor caches will
maintain coherency.
• S3: Suspend to RAM (Instantly Available PC Technology).
• S4: Hibernate or Save to Disk. The memory and machine state are saved to disk. Pressing the
power button or another wake-up event restores the system state from the disk and resumes
normal operation. This state assumes that no hardware changes were made to the system while
it was off.
• S5: Soft off. Only the RTC section of the chipset is running in this state.
CAUTION
The system is off only when the AC power is disconnected.
Table 8 lists the system states based on how long the power switch is pressed, depending on how
ACPI is configured with an ACPI-aware operating system.

Wake-up Devices and Events
CAUTION
For LAN wake capabilities, the 5 V standby line for the power supply must
be capable of providing adequate +5 V standby current. Failure to provide
adequate standby current when implementing LAN wake capabilities can
damage the power supply.
Table 9 provides an overview of the devices or events that can wake the computer from specific
states.

NOTE
✏
The use of these wake-up events from an ACPI state requires an operating
system that provides full ACPI support. In addition, software, drivers, and
peripherals must fully support ACPI wake events.
LAN Wake
LAN wake capabilities enable remote wake-up of the computer through a network. The LAN
subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface.
Upon detecting a Magic Packet
*
frame, the LAN subsystem asserts a wake-up signal that wakes up
the computer from ACPI S1, S3, S4, and S5 state.
Depending on the LAN implementation, the S875WP1-E server board supports LAN wake
capabilities with ACPI in the following ways:
• The PCI bus PME# signal for PCI 2.2 compliant LAN designs
• The onboard LAN subsystem
PCI via PME# Wake-up Support
When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or
S5 state (with Wake on PME enabled in BIOS).
26 Intel Server Board S875WP1-E Product Guide
Resume on Ring
Resume on Ring enables telephony devices to access the computer when it is in a power-managed
state. The operation of Resume on Ring wakes the system from the S1 or S3 sleep states when a
signal is sent to the serial port at the rear or the chassis or to an internally installed modem. Resume
on ring can be summarized as follows:
• Resumes operation from ACPI S1 or S3 states
• Requires only one call to access the computer
• Detects incoming call similarly for external and internal modems
• Requires modem interrupt be unmasked for correct operation
Wake from USB
USB bus activity wakes the computer from an ACPI S1 or S3 state.
NOTE
✏
Wake from USB requires the use of a USB peripheral that supports Wake
from USB.
Wake from PS/2 Devices
PS/2 device activity, such as moving a PS/2 mouse or pressing a key on a PS/2 keyboard, wakes the
computer from an ACPI S1 or S3 state.
Hardware Support
The S875WP1-E server board provides several power management hardware features, including:
• Power connector
• Fan connectors
• Instantly Available PC technology
Instantly Available PC technology and LAN Wake require power from the +5 V standby line. The
sections discussing these features describe the incremental standby power requirements.
CAUTION
Ensure that the power supply provides adequate +5 V standby current if
Instantly Available PC technology features is used. Failure to do so can
damage the power supply. The total amount of standby current required
depends on the wake devices supported and manufacturing options.
Server Board Features 27
Power Connector
When used with an ATX12V or EPS12V compliant power supply that supports remote power
on/off, the S875WP1-E server board can turn off the system power through software control.
When the system BIOS receives the correct command from the operating system, the BIOS turns
off power to the computer.
With soft-off enabled, if power to the computer is interrupted by a power outage or a disconnected
power cord, when power resumes, the computer returns to the power state it was in before power
was interrupted (on or off). The computer’s response can be set using the After Power Failure
feature in the BIOS Setup program’s Boot menu.
NOTE
✏
A standard ATX 20 pin power connector and standard ATX 12V 4-pin 2x2
connector can be used to power the S875WP1-E board. Plug the power
cables into the pin 1 end of their respective motherboard connectors, leaving
pins 21-24 unused on the main power connector and 5-8 unused on the 12V
connector.

Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, the +5 V standby line for the power
supply must be capable of providing adequate +5 V standby current. Failure
to provide adequate standby current when implementing Instantly Available
PC technology can damage the power supply.
The S875WP1-E server board supports the PCI Bus Power Management Interface Specification.
An add-in board that supports this specification can participate in power management and can be
used to wake the computer.
The use of Instantly Available PC technology requires operating system support and PCI 2.2
compliant add-in cards and drivers.
The standby power indicator LED shows that power is still present even when the computer
appears to be off. Figure 4 shows the location of the standby power indicator LED.
CAUTION
If AC power has been switched off and the standby power indicator is still lit,
disconnect the power cord before installing or removing any devices
connected to the board. Failure to do so could damage the board and any
attached devices.
