Page 20
1-4 Compaq ProLiant ML750 Servers Setup and Installation Guide
PCI Hot Plug
PCI Hot Plug provides the ability to remove, replace, upgrade, and add PCI
expansion boards without powering down the server. Any PCI board can be
placed in a PCI Hot Plug slot. PCI Hot Plug device drivers and operating
system support, however, are required to enable PCI Hot Plug.
The PCI Hot Plug button allows for PCI Hot Plug access directly at each PCI
slot. A PCI Hot Plug button is located above each PCI slot, providing PCI
Hot Plug control directly at the server without the use of the PCI Hot Plug
utility software.
NOTE: To optimize the management features of the Remote Insight Board/PCI, it is not
hot-pluggable.
For more information about PCI Hot Plug, refer to the server Documentation
CD.
Redundant Hot-Plug Power Supplies

WARNING: Hot-plug power supplies are not designed to be installed with AC
current connected to the power supply. To prevent personal injury or damage to
the equipment, be sure to disconnect the power supply from AC current prior to
its removal or installation.
Power supplies are load-balancing and have microcontroller monitoring
for advanced health and configuration management.
Supports up to three power supplies. Depending upon the system load
configuration, more than one power supply may be required to power
the system. See the section, “Power Requirements,” in Chapter 2 to
determine power supply requirements.
A power supply security bar and a padlock provide additional security.
Page 21
Introduction 1-5
Hot-Plug Redundant Fans
ProLiant ML750 servers include hot-plug redundant fans that provide high-
level thermal protection. A failed fan generates a system alert and triggers the
secondary (or redundant) fan to take over automatically. Hot-plug redundant
fans protect the various server components from overheating and the system
from possible interruption.
Internal Hot-Plug Drive Bays
The ProLiant ML750 server supports up to three ProLiant ML750
Ultra3 SCSI internal drive cages.
The ProLiant ML750 internal drive cage is capable of supporting a
maximum of seven 1-inch Ultra3 hot-plug drives (totaling 21 drives
with all three 1-inch drive cages installed).
Hot-plug drives may be any storage capacity of 9.1 GB or greater.
Internal Removable Media Drive Bays
Supports three non-hot plug removable media drive bays:
One third-height drive bay occupied by a slimline 3.5-inch diskette/IDE
CD-ROM drive combination
Two half-height 5.25-inch drive bays available
Disk Controllers
Supported disk controllers include:
Up to two Smart Array 4250ES Controllers or other Compaq array
controllers with Extended SCSI. A Compaq array controller with
Extended SCSI provides high performance and RAID fault tolerance.
The Compaq array controller with Extended SCSI is cableless and
connects to the three Ultra3 SCSI buses on the I/O board for use with
internal mass storage. SCSI cables are preinstalled between Ultra3 SCSI
connectors on the I/O board and each internal drive cage installed.
Adding a redundant Compaq array controller with Extended SCSI
allows the server to continue functioning in the event of an array
controller failure.
Page 22
1-6 Compaq ProLiant ML750 Servers Setup and Installation Guide
One or more Smart Array 3200 or 4200 Controllers, which may be
installed in any slot. The Smart Array Controller supports up to two
internal drive cages or external mass storage devices and requires a
SCSI cable connection between the controller and the drive cages or
external mass storage devices.
One or more Dual-Channel Ultra2 Controller cards for use with internal
removable media drive bays, internal drive cages, or external mass
storage devices.
NOTE: The ProLiant ML750 server does not include an integrated SCSI controller.
Network Controllers
Supports a dual-port 10/100 TX UTP controller on a PCI local bus.
Depending on the model, features of the controller may include:
G Two RJ-45 connectors for 10BaseT or 100BaseTX Ethernet
G Upgradable with a daughter card to an additional two ports of
100BaseTX Ethernet, a single port of 100BaseFX, or a single port of
Gigabit Ethernet SX or LX Fiber support
G Auto-Negotiation for hardware selection of the highest operating
speed
Redundant Network Controller software that supports a redundant NIC
configuration is available. This feature may be used with one dual-port,
two dual-port, or two single-port NICs.

System Power Management Guidelines
Unless the server is operating with two 1150/500-W power supplies (three for
N+1 redundancy) at 220-V, it may be necessary to make trade-offs with
respect to which options can be added and powered with the installed power
supplies. Use the following guidelines when evaluating these trade-offs.
NOTE: The following guidelines are general. Use the Windows NT Power Supply Viewer
Utility or Novell NetWare Compaq Power Subsystem Utility and option documentation to
obtain the most accurate power capacity and assessment of power margin.
Comparing processor and hard drive power: Two processors draw as
much current as five to six hard drives.
Comparing memory and 3.3-V-powered PCI expansion board power:
Each additional 512 MB draws approximately as much current as one to
two PCI boards.
Comparing 5-V-powered PCI expansion board and hard drive power:
One PCI card draws as much current as two to five hard drives.
In general, PCI array controllers draw more current than PCI NICs.
For example, if the available capacity of the installed power supplies permits
adding two processors, you have the option of adding:
Two processors, or
One processor and three hard drives, or
Up to six hard drives
Grounding Requirements
For proper operation and safety, proper grounding of this equipment in
accordance with NFPA 70-1993 (National Electric Code), Article 250, as well
as any local and regional building codes, is required. All power distribution
devices, branch wiring, and receptacles must be listed grounding-type devices.
Due to the higher ground-leakage currents associated with the equipment,
Compaq recommends the use of a Power Distribution Unit (PDU) that
provides a supplementary ground conductor. This supplementary ground
conductor should be permanently connected to a suitable building ground
terminal. The use of common power outlet strips for this equipment is not
recommended.
Page 37
2-6 Compaq ProLiant ML750 Servers Setup and Installation Guide
In Canada, the equipment should be installed in accordance with Canadian
Standards Association, CSA C22.1, Canadian Electrical Code. In all other
countries the installation should follow any regional or national electrical
wiring codes such as the International Electrotechnical Commission
(IEC) 364, parts 1 through 7. All power distribution devices used in the
installation, including branch wiring, receptacles, and so on, should be listed
or certified grounding-type devices.
WARNING: To reduce the risk of electric shock or damage to the equipment:
Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
Plug the power cord into a grounded (earthed) electrical outlet that is
easily accessible at all times.
Disconnect power from the server by unplugging the power cord from
either the electrical outlet or the server.
When using power strips for electrical distribution, make sure that ground
integrity is maintained for each connection made. Plug each component into a
reliably grounded outlet.
Temperature Requirements
To ensure continued safe and reliable operation of the equipment, install/place
the system in a well-ventilated, climate-controlled environment.
The Compaq Maximum Recommended Ambient Operating Temperature
(TMRA) for most server products is 35°C (95°F). The temperature in the room
where the rack is located should not exceed 35°C (95°F).
Page 38
Server Installation 2-7
The operating temperature inside the rack will always be higher than the room
temperature and is dependent on the configuration of equipment in your rack.
The TMRA for each piece of equipment should be checked before installation.
The maximum internal rack temperature for your configuration should not
exceed the values shown in Table 2-2.
Table 2-2
Rack Internal Temperature Maximums
Equipment Included Maximum Internal Rack Temperature
Rack-Mountable ProLiant servers 43°C/122°F
Compaq Rack-Mountable options 40°C/104°F
Other manufacturers’ options See other manufacturers’ specifications
Note: All temperature ratings shown are for sea level. There is an altitude derating of 1.8°F
per 1,000 ft to 10,000 ft (1°C per 300 m to 3,000 m).
CAUTION: To reduce the risk of damage to the equipment when installing
third-party options:
Make sure that the optional equipment does not impede airflow to the
rack-mountable ProLiant servers or increase the internal rack temperature
beyond the Compaq-specified maximum rating.
Make sure that the Manufacturer’s Maximum Recommended Ambient
Operating Temperature of the optional equipment is not exceeded when
the options are installed in the rack.
Page 39
2-8 Compaq ProLiant ML750 Servers Setup and Installation Guide
Airflow Requirements
The Compaq ProLiant ML750 server draws cool air in through the front door
and exhausts warm air out the rear door. Therefore, the front door of the rack
must be adequately ventilated to allow ambient room air to enter the cabinet,
and the rear door must be ventilated adequately to allow the warm air to
escape from the cabinet. Do not block the ventilation apertures.
CAUTION: If a third-party rack is used, the following minimum requirements
should be observed to ensure adequate airflow and to prevent damage to the
equipment:
Front: The rack door should have 120 square inches (305 cm
2
) of holes
evenly distributed from top to bottom to permit adequate airflow.
Side: The clearance between the installed module and the side panels of
the rack should be a minimum of 2.75 inches (7 cm).
Rear: The clearance between the back of the rack and the wall should be a
minimum of 30 inches (76 cm), and the equipment should be operating
without a rear door.
CAUTION: If all of the vertical space in the rack is not filled by components, the
gaps left will cause a change in airflow through the rack and across the
components. These gaps must be covered with blanking panels.
High Airflow Rack Door Insert
The increased power of new processor technology requires increased cooling
efficiency for rack-mounted servers. The new Compaq Rack 9000 series
provides enhanced airflow for maximum cooling, allowing these racks to be
fully loaded with servers using the latest processors.
When installing this server in Compaq Rack 7000 and 4000 series the new
processor technology requires the installation of a new Compaq High Airflow
Rack Door Insert, if the rack has a LEXAN front door.

System Power
The system power in the ProLiant ML750 server does not shut off completely
with the front panel Power On/Standby switch. The two modes of the power
switch are ON and STANDBY, rather than ON and OFF. The STANDBY
position removes power from most of the electronics and the drives, but
portions of the power supply, the Integrated Management Display (IMD), the
system interlock circuitry and some internal circuitry remain active.
To remove all power from the system completely, you must disconnect all
power cords from the server.
WARNING: To reduce the risk of electric shock or damage to the equipment:
Do not disable the power cord grounding plug. The grounding plug is an
important safety feature.
Plug the power cord into a grounded (earthed) electrical outlet that is
easily accessible at all times.
Disconnect power from the server by unplugging the power cord from
either the electrical outlet or the server.
CAUTION: Electrostatic discharge can damage electronic components. Be sure
you are properly grounded before beginning any installation procedure. See
Appendix B, “Electrostatic Discharge,” for more information.
Powering Up the Server
You can now bring your ProLiant ML750 server online in accordance with
your network and operating system procedures. When you power on the
server, it should go through the following sequence. Record any discrepancies
and any error messages that appear.
1. Verify that system interlocks are met. See “System Interlocks” later in
the chapter.
2. Press and release the Power On/Standby switch. The front panel system
LED will blink as the power supplies initialize. If the LED does not
blink, there is no power to the system. When the power comes on, the
LED will remain lit.
A steady green system LED indicates that the server is powered on. If
the system LED is amber, the system interlock chain is not complete.
See the “System Interlocks” section later in the chapter for further
instructions. If the system LED blinks once every 10-20 seconds, the
system is trying to start but may have a short.
Page 63
Server Operation 3-3
3. Check the power supplies. The following settings indicate that the
power switch is on and the power supply is in a “power on” delay mode:
G Top LED begins flashing (green). If the top power supply LED does
not begin flashing (the server will not power on), refer to the
“System Interlocks” section later in the chapter.
G Bottom LED ON (solid green).
4. When the top LED turns solid green, listen for the fans to start. Watch
for the following:
G The hard drive LEDs should blink. If the LEDs do not light, power
down the server and check the cable connection to the hard drive
cages. Also, check connections between the hard drive and its drive
cage.
G The green LEDs on the external fans should be on. If the LEDs do
not light, there is no power to the fans. Ensure that the fan cables are
properly installed at the fans, fan boards, processor board, and I/O
board.
If you have an IMD, check the following. If you have a monitor, check for the
steps listing monitor displays.
5. Check the IMD for messages about the:
G Server name
G LCD firmware
G System initialization
G PCI auto configuration
G Processors
6. Check the IMD video message. If there is a monitor connected, you
should see the Compaq initialization screen.
7. Check for the IMD memory test message. The monitor shows the
memory count and the memory initialization.
8. Observe the memory count displayed.
9. Check for the IMD BIOS message. The monitor shows the number of
processors, their speed, and their cache size.
10. Check the IMD for messages about:

Server Operation 3-5
Powering Down the Server
The system power in the ProLiant ML750 server does not shut off completely
with the front panel Power On/Standby switch. The two power states of the
switch function as ON and Standby, rather than ON and OFF. The Standby
power state removes power from most of the electronics and the drives, but
portions of the power supply, the Integrated Management Display (IMD), the
system interlock circuitry, and some internal circuitry remain active. To
completely remove all power from the system, disconnect all power cords
from the server.
WARNING: To reduce the risk of electric shock or damage to
the equipment, disconnect power from the server by
unplugging all power cords from either the electrical outlet or
the server.
To completely remove power from the server:

Installing a Pentium III Xeon Processor
and Redundant Processor Power Module
The ProLiant ML750 server is capable of supporting up to eight processors
and Processor Power Modules. An additional processor board Processor Power
Module is installed to power the processor board.
CAUTION: Handle the processor only by the ejectors and, only if necessary, lay
the processor on its back (the plastic side with the hologram) to prevent damage
to the heat pipes and fins.
CAUTION: The redundant Processor Power Module must be installed before the
corresponding processor. Attempting to install the Processor Power Module
after the processor has been installed could damage the Processor Power
Module.
IMPORTANT: For best performance, install the first four processors in Processor
Slots 1 through 4. Cache Accelerators must be used if processors are installed on both
buses.
Operating the server with processors installed in both buses but without the Cache
Accelerators will prevent the system from booting and cause an error message to be
displayed. See the “Installing Cache Accelerators” section later in this chapter for more
information.
NOTE: Be sure to keep processor terminator boards as processors are added. The
processor terminator boards can be used in the event of a processor failure so that the
server will run with the remaining processors.

When installing new processors, it is important to follow these guidelines:
All processors must be Intel Pentium III Xeon processors. The
ProLiant ML750 server does not support Pentium II Xeon processors.
Processors must be installed starting from the slot closest to the rear of
the server (Slot 1).
Each pair of processor slots must contain processors of the same cache
size (processor slot pairs are: Slots 1 and 2, Slots 3 and 4, Slots 5 and 6,
Slots 7 and 8). If there is no match for a processor, the second slot in the
pair must be filled with a processor terminator board.
The processor pair with the lowest cache size should be installed closest
to the rear of the server. If a second pair of processors has a larger cache
size, it should be installed in the next pair of slots.
CAUTION: The server will not boot if the Intel Pentium III Xeon processors are
not the same speed.

With the bus/core ratio switches in the default position, the system ROM will
automatically detect the speed of processors installed on both processor buses.
The processors will automatically run at the speed of the slowest processor
installed in the server.
The default setting for the bus/core ratio switches is all switches OFF. Compaq
recommends that the bus/core ratio switches remain on the default setting to
allow the system ROM to automatically detect the correct speed.

Installing Cache Accelerators
Cache Accelerators must be added when processors are installed on more than
one processor bus. If both buses are populated but Cache Accelerators are not
installed, the system will not boot and an error message will be displayed. The
Cache Accelerators are available in the Cache Accelerator option kit
(part number 328819-B21). To install the Cache Accelerators, follow the
directions below.
CAUTION: The Cache Accelerators are susceptible to damage from electrostatic
discharge. Follow the guidelines in Appendix B for preventing electrostatic
discharge.

SDRAM Memory
You can expand computer memory by installing industry-standard Dual Inline
Memory Modules (DIMMs) into the memory expansion boards. Be aware of
the following when installing additional memory:
Server supports 100-MHz SDRAM 128-MB, 256-MB, 512-MB, or
1-GB DIMMs.
Memory is expandable to 16 GB (16 × 1-GB DIMMs).
Groups of two DIMMs of the same size, type, and speed must be
installed or removed at a time (the eight groups on the memory
expansion board are referred to as Banks 1 through 8).
CAUTION: Compaq recommends the use of Compaq DIMMs. DIMMs from other
sources may adversely affect data integrity.
Page 99
Installing Hardware Options 4-19
IMPORTANT: Memory must be installed in identical pairs. Ensure all modules in a logical
bank of two have the same 9-digit Compaq part number. Populate bank 1 (slots 1 and 2)
first. Continue populating the memory banks in sequential order. Populate bank 8 last. If
the memory is not matched as stated, then the server will experience POST Error 207.
To install more memory, refer to one of the following installation sources:
For an illustrated overview of the installation procedure, refer to the
