DIMMs
• Twelve deep in-order queue
• Full support of registered DDR266 ECC DIMMs
• Support for up to 8 GB of DDR memory
• Memory scrubbing
Description 13
P64H2 I/O Hub
The primary role of the P64H2 is to provide an integrated I/O bridge to the 64-bit PCI-X segments.
This subsystem supports two independent 64-bit PCI-X segments, each with two 64-bit/100MHz
PCI-X slots. The Adaptec AIC-7901 embedded controller is enabled via one of the PCI-X
segments of the P64H2.
ICH3 I/O Controller Hub
The primary role of the ICH3 is to provide the gateway to all PC-compatible I/O devices and
features. The SE7501BR2 uses the following ICH3 features:
• 32-bit/33 MHz PCI bus interface
• Low Pin Count (LPC) bus interface
• IDE interface, with Ultra DMA 100 capability
• Universal Serial Bus (USB) interface
• PC-compatible timer/counter and DMA controllers
• APIC and 8259 interrupt controller
• Power management
• General purpose I/O
• System RTC
Super I/O
The National Semiconductor† PC87417 Super I/O Plug-and-Play Compatible with
ACPI-Compliant Controller/Extender is used on the SE7501BR2 server board. This device
provides the system with:
• Two serial ports
• One parallel port
• Floppy disk controller (FDC)
• PS/2†-compatible keyboard and mouse controller
• Wake event control
Serial Ports
One DB9 connector is provided on the back panel for the Serial A port. The Serial A port is
compatible with 16550A and 16450 modes. This port can be set to one of four different
COM ports, each of which can be enabled separately. When enabled, each port can be programmed
to generate edge- or level-sensitive interrupts. When disabled, the serial port interrupts are
available for add-in cards.
A DH10 10-pin serial header is available on the baseboard for an optional Serial B port. The
Serial B port can be used as an Emergency Management Port.
Parallel Port
The SE7501BR2 baseboard provides a 25-pin parallel port back panel connector. The Super I/O
provides an IEEE 1284-compliant 25-pin bi-directional parallel port. BIOS programming of the
Super I/O registers enables the parallel port and determines the port address and interrupt. When
disabled, the interrupt is available to add-in cards.
14 Intel Server Board SE7501BR2 Product Guide
Floppy Disk Connector
The floppy disk connector on the server board provides the interface to the floppy disk drive from
the floppy disk controller.
Keyboard and Mouse Connectors
The separate keyboard and mouse connectors, found on the back panel of the server board, are
PS/2-compatible. The keyboard and mouse connectors are interchangeable.
Processor(s)
The Intel?? Server Board SE7501BR2 accommodates one or two Intel Xeon processors with 512KB
L2 Cache via two SKT604 604-pin zero-insertion force (ZIF) sockets. The processors interface
with the system bus at 533 MHz, backwards compatible with 400 MHz. When only one processor
is installed, it should be in the socket labeled CPU1 and the other socket must be empty.
For a complete list of supported processors, see:
http://support.intel.com/support/motherboards/server/SE7501BR2
Dual Processor Operation
The Intel Xeon processor interface is dual-processor (DP)-ready. The processor subsystem
includes a single VR (Voltage Regulator) to support both processors. Interrupt generation and
notification for the processors is done by the Advanced Programmable Interrupt Controllers
(APICs) in the ICH3 and P64H2. When two processors are installed, both processors must be of
identical revision, core voltage, and bus/core speeds.
Boxed Processor Fan Heat Sink
Complete thermal solution including a processor wind tunnel (PWT), fan, and heatsink is supplied
with each boxed Intel Xeon processor.
✏ NOTE
Do not install the Processor Wind Tunnel when using the Intel?? Server Chassis
SC5200 with hot swap redundant power. To install the heat sink you must use
the Retention Mechanisms supplied with the SC5200 chassis. For this chassis,
see the installation instructions beginning on page 47.
Otherwise, install the processor wind tunnels according to the instructions
provided in this document or in the SE7501BR2 Quick Start User’s Guide. These
instructions are different than those included with the boxed processor. For
proper processor cooling, the fan inlet air temperature should be below 45 °C.
CAUTION
Clearance is required at each end of the fan heat sink to ensure unimpeded
airflow for proper cooling. Restricting the airflow through the processor heat
sink can cause overheating and subsequent failure of the processor.
Description 15
Memory
The Intel?? Server Board SE7501BR2 contains four 184-pin DIMM sockets and provides support
for up to 8 GB of DDR266 memory. The memory subsystem provides dual memory bus
architecture; the memory on the board is partitioned into two banks of DDR DIMMs. DIMMs must
be installed in pairs, providing a 144-bit wide data path via two separate memory buses.
The server board supports up to four ECC DDR DIMMs that are compliant with the JEDEC
DDR266 specification. A wide range of DIMM sizes are supported, including:
• 128 MB
• 256 MB
• 512 MB
• 1 GB
• 2 GB
The minimum supported memory configuration is 256 MB, using two 128 MB DIMMs. The
maximum configurable memory size is 8 GB using four 2 GB DIMMs.
✏ NOTE
DIMMs must be installed in pairs and must be populated by bank starting
with DIMM 1A and 1B (contiguous sockets). Although the SE7501BR2
server board architecture allows the user to mix various sizes of DIMMs
between banks, DIMMs must be identical within the banks. For a list of
tested memory, see:
http://support.intel.com/support/motherboards/server/SE7501BR2
PCI I/O Subsystem
The SE7501BR2 server board provides three PCI bus segments:
• Segment C with two PCI-X 64-bit / 100 MHz slots (Slot 1 and 2)3
• Segment B with two PCI-X 64-bit / 100 MHz slots (Slot 3 and 4)4
• Segment A with two PCI 32-bit / 33 MHz slots (Slot 5 and 6)
The following table outlines the capabilities of each 64-bit bus segment. The least capable card
installed on that bus determines the bus mode/speed. In other words, the bus will run at the speed
of the slowest installed card.
Table 2. 64-bit PCI Segment Configuration
# of slots populated per segment Segment B (mode, speed) Segment C (mode, speed)
0 PCI-X, 100 MHz PCI-X, 133 MHz
1 PCI-X, 100 MHz PCI-X, 133 MHz
2 PCI-X, 100 MHz PCI-X, 100 MHz
3 This segment will operate at 133 MHz when only one slot is populated.
4 Modular RAID on Motherboard (M-ROMB) support is provided via Slot 4.
16 Intel Server Board SE7501BR2 Product Guide
Segment C: 64-bit / 100 MHz PCI-X Capable Subsystem
The 64-bit/100 MHz PCI-X segment includes:
• Two 3.3 V keyed full-length, full height PCI expansion slots that can support PCI-X add in
cards up to 133 MHz (PCI-X Slots1 and 2). These slots are backward compatible to 64-bit/100
MHz, 64-bit/66 MHz, 64-bit/33 MHz, and universal keyed 32-bit/33 MHz PCI cards.
The PCI-X features include:
• Bus speed up to 133 MHz
• 3.3 V signaling environment
• Burst transfers up to a peak of 1000 Megabytes per second (MB/s)
• 8-, 16-, 32-, or 64- bit data transfers
• Plug-and-Play ready
• Parity enabled
✏ NOTES
Speed on the PCI-X will be programmed by the BIOS according to loading on the
segment. When a segment is configured with a single PCI-X 64/133 card the bus
will work at 133 MHz; with two PCI-X 64/133 cards the bus will work at 100
MHz.
If you install a slower card into one of the PCI-X 64/100 connectors, the bus speed
for both connectors will be lowered to the speed of the slowest adapter.

ACPI
By using Advanced Configuration and Power Interface (ACPI), an ACPI-aware operating system
can place the system into a state in which 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.
✏ NOTE
ACPI requires an operating system that supports this feature.
The server board supports sleep states S0, S1, S4, and S5. When the server board is operating in
ACPI mode, the operating system retains control of the system and the OS 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.
• S0: Normal running state.
• S1: DC Power remains on. The operating system saves the context and enters a low-power
state. The system can wake from the S1 state using a PS/2 keyboard, mouse, or USB device,
by pressing the power button press, or from a wakeup event.
• S4: Hibernate or Save to Disk. The memory and machine state are saved to disk. Pressing the
power button or another wakeup event restores the system state from the disk and resumes
normal operation. This assumes that no hardware changes were made to the system while it
was off.
• S5: Soft off. Only the RTC section of the chip set is running in this state.
CAUTION
The system is off only when the AC power is disconnected.
Wakeup Events
The SE7501BR2 system supports several wakeup events.
Wake on LAN
Wake on LAN allows system power to be activated through the network. If the system is in the S1
or S4 state, it can be turned on remotely by sending a specific packet to the remote system. The
system contains a configuration option that allows the on-board NICs to be enabled to wake the
system from a S4 or S5 sleep state, even if the operating system disabled Wake on LAN when it
powered down the system. This provides an option for users who want to use standard, but
non-secure, Wake on LAN capability for operations such as after-hours maintenance. Server
management features provide a secure system power-up, plus the ability to provide BIOS boot
option.
Description 21
Wake on Ring
Wake on Ring allows system power to be activated through the serial ports when this option is
enabled in Setup. If the system is in the S1 or S4 state, it can be turned on remotely by the Ring
Indicate RI signals from the serial ports.
✏ NOTE
Wake on Ring is disabled in Serial B if this port is enabled as a server
management port.
Wake on RTC Alarm
Wake on RTC alarm allows system power to be activated through a real-time clock alarm when this
option is enabled in Setup. If the system is in the S1 or S4 state, it can be turned on by an RTC
trigger event.
System Management
Intel integrates system management features into the hardware and provides additional features
through Intel?? Server Management (ISM) software version 5.5. A brief description of the features
is provided below. For instructions on using the features described, refer to the Configuration
Software and Utilities chapter, beginning on page 77.
Baseboard Management Controller
Intel server boards incorporate a baseboard management controller (BMC), which is a dedicated
microcontroller for system management activities. The BMC performs the following functions:
• Monitors system components and sensors, including processors, memory, fans, power supplies,
temperature sensors, and chassis intrusion sensors.
• Manages nonvolatile storage for the system event log (SEL), sensor data records (SDRs), and
baseboard field-replaceable unit (FRU) inventory.
• Interfaces with the emergency management port (EMP) and LAN1 port to send alerts and
interact with remote management systems.
• Provides the main front panel control functions (power on/off, reset, and so on).
22 Intel Server Board SE7501BR2 Product Guide
Field Replaceable Units and Sensor Data Records
Field replaceable units (FRUs) are major modules in the chassis that contain active electronic
circuitry. FRUs can store information-such as board serial number, part number, name, and asset
tag-that can be read using the System Setup Utility. The BMC stores FRU information for the
baseboard in a nonvolatile storage component on the board.
The BMC uses Sensor Data Records (SDRs) to identify the sensors in the system for monitoring.
SDRs provide a list of the sensors, their characteristics, location, type, and type-specific
information, such as default threshold values, factors for converting a sensor reading into the
appropriate units (mV, rpm, degrees Celsius), and information on the types of events that a sensor
can generate. The BMC stores SDR information in a nonvolatile storage component on the
baseboard.
You can use the FRU/SDR Load Utility to initialize or update the FRU and SDR information.
Intel?? server boards are shipped from the factory with some sensors disabled because the actual
configuration of the chassis is only determined when the user completes the system configuration.
For example, chassis-specific FRU information, such as chassis part number, must be configured
when the system is configured. For these reasons, it is important to run the FRU/SDR Load Utility
as part of the system setup process. You should also run the FRU/SDR Load Utility whenever you
change the number of fans, processors, or power supplies in the server.
System Event Log
The BMC manages a system event log (SEL), where it records significant or critical system events.
These events include temperatures and voltages out of range, fan failures, and other sensor-related
events. The BIOS, software, and other devices can also log events by sending messages to the
BMC. The SEL is stored in nonvolatile storage.
You can view the current contents of the SEL by using the System Setup Utility.
Platform Event Management
Events can trigger alerts and other actions by the BMC. The server is configured with the
following set of standard events:
• Temperature sensor out of range
• Voltage sensor out of range
• Fan failure
• Chassis intrusion
• Power supply failure
• Memory error
• POST error
• Processor fault resilient booting (FRB) failure
• Fatal nonmaskable interrupt (NMI) from a source other than the front panel switch
• Watchdog timer reset, power down, or power cycle
• System restart (reboot)
Description 23
Alerts can take either of these forms:
• Platform Event Pages – the BMC dials a paging service and sends a predefined paging string.
To use platform event paging (PEP), you must attach an external modem to the emergency
management port (Serial B). Use the Server Configuration Wizard to configure the pager and
emergency management port information.
• BMC LAN alerts – the BMC sends an alert to a predefined destination on the LAN.
You can configure PEP and BMC LAN alerts by using the Server Configuration Wizard or the
System Setup Utility.
Emergency Management Port
The emergency management port (EMP) refers to the use of the Serial B port, with either an
external modem or direct serial connection, for remote management. The BMC controls the port
and interfaces with remote access software, such as the Direct Platform Control or the Client
System Setup Utility applications in Intel Server Management.
You can configure the EMP by using the Server Configuration Wizard or the System Setup Utility.
EMP and Serial Over LAN
The Serial B port 10-pin header on the board can be configured in several different ways: as a
standard serial port, as an Emergency Management Port, or for serial output redirection over a
LAN. You can configure these settings using either the System Setup Utility or the Server
Configuration Wizard.
✏✏ NOTES
SC5200 Server Chassis considerations: If you have configured the Serial
B port for use as an emergency management port and set it to be “always
available”, the Serial B port will be accessible only by remote server
management software. The operating system will never be able to access the
port.
If you have configured the Serial B port for Serial Over LAN, the port’s
functionality will be impacted only when there is an active Serial Over LAN
session from a remote console. At all other times either the operating system
or the EMP will control the port, depending on your configuration.
24 Intel Server Board SE7501BR2 Product Guide
Intel?? Server Management
Intel Server Management (ISM) version 5.5 is a system management package that is included on
the ISM CD. ISM applications interact with the integrated hardware system management features
of the server to allow you to monitor and manage a server. Version 5.5 provides integrated in-band
(operating system up) and out-of-band (operating system down) remote management, event alerting
and logging, including e-mail notification, and proactive fault management. Some of the features
provided are:
• The ability to connect to the server from a Windows†-based client workstation over a LAN
over a modem, or over a direct serial connection to the server, permitting you to manage the
server from a remote location.
• Real-time monitoring and alerting for server hardware sensors.
• Emergency management when the server is off (but still connected to AC power) lets you
verify the state of the server, diagnose hardware problems, and power on/off or reset the server.
• The ability to run the Client System Setup Utility to change the configuration of the managed
server.
ISM can use an optional service partition on the managed server. The service partition is a special
disk partition on the system drive that contains a ROM-DOS† operating system and DOS-based
utilities, including the System Setup Utility, FRU/SDR Load Utility, and other diagnostics
packages you might choose to install. The server can be booted to the service partition, either
locally or remotely, to provide access to the utilities.
The service partition must be installed before the operating system is installed. Instructions for
creating a service partition are available on the Quick Start Users guide.
For more information on Intel Server Management and the individual ISM applications, see the
Intel Server Management Installation and User’s Guide on the ISM CD.

26 Intel Server Board SE7501BR2 Product Guide
Secure Mode
Secure mode refers to a system state where many of the external inputs and outputs are disabled to
prevent tampering. These include PS/2 ports, floppy and on-board video. When secure mode is in
effect, you must enter a password before the system will accept any keyboard or mouse input,
except for the password entry. When secure mode is in effect, you cannot turn off the system
power or reset the server from the front panel switches.
Secure mode has no effect on functions enabled via remote server management or power control
via the watchdog timer.
Taking the system out of secure mode does not change the state of system power. In other words, if
you press and release the power button while secure mode is in effect, the system will not be
powered down when secure mode is later removed. However, if the front panel power button
remains depressed while secure mode is removed, the server will be powered off.
Secure mode is configured through the BIOS setup options or through the System Setup Utility.
Hot Key Activation
A hot key combination allows the user to activate secure mode immediately instead of waiting for
the configured inactivity time-out to expire. The hot key combination is configured through Setup.
Either Ctrl-Alt-L or Ctrl-Alt-Z can be configured as valid hot keys.
✏ NOTE
Hot keys work only with PS/2 keyboards.
Secure Boot Mode (Unattended Start)
The Secure Boot mode allows the system to boot and run the operating system without requiring
the user password, even if the user password is set. However, until the user password is entered,
mouse and keyboard input is not accepted (except for password entry). If Secure Boot is enabled,
secure mode is enabled shortly before boot. To prevent unauthorized tampering with any option
ROM based setup utilities, enable the “Option ROM Menu Mask” setting in the security menu.
Using Secure Boot
When secure mode is in effect:
• You can boot the server and the operating system will run, but you must enter the user
password to use the keyboard or mouse.
• You cannot turn off system power or reset the server from the front panel switches.
Secure mode has no effect on functions enabled via the Server Manager Module or power control
via the real time clock.
Description 27
Password Protection
The BIOS uses passwords to prevent unauthorized tampering with the system.
Entering the user password permits the modification of the time, date, language, user password, and
password on boot setup fields. When a user password is configured, the server can be booted into
secure mode. See the Secure Boot Mode (Unattended Start) section above. Other setup fields can
be modified only if the administrator password is entered.
If a wrong password is entered three times in a row, the BIOS stops validating passwords and the
BIOS security engine returns a failure for any further password validation attempt. If the user
enters three wrong passwords in a row during the boot sequence (i.e., when entering Setup), the
system is placed into a halt state. This feature makes is difficult to break the password by the “trial
and error” method. When entering a password, the backspace key is accepted as a character of the
password. Pressing the backspace key to replace a mistyped character will result in a wrong
password.
If the user or administrator password is lost or forgotten, the password clear jumper can be used to
clear both passwords. See Chapter 5 under “Clearing the Passwords with the Password Clear
Jumper.”
If only the administrator password is set, you:
• Must enter the administrator password to enter BIOS Setup.
• Must enter the administrator password to boot the server if Password on Boot is enabled in the
BIOS Setup.
• Must enter the administrator password to exit secure mode.
If both passwords are set, you:
• May enter the user password to enter BIOS Setup. However, you will not be able to change
many of the options.
• Must enter the administrator password if you want to enter BIOS Setup and have access to all
of the options.
• May enter either password to boot the server if Password on Boot is enabled in the BIOS Setup.
• May enter either password to exit secure mode.
Setting Passwords
Each password can be independently set or cleared in the BIOS setu
