Compaq Technician Notes
WARNING: To reduce the risk of personal injury from electric shock and hazardous energy
levels, do not exceed the level of repair specified in these procedures. Because of the
complexity of the individual boards and subassemblies, do not attempt to make repairs at the
component level or to make modifications to any printed wiring board. Improper repairs could
create conditions that are hazardous.
WARNING: To reduce the risk of electric shock or damage to the equipment:
■ If the system has multiple power supplies, disconnect power from the system by
unplugging all power cords from the power supplies.
■ 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.
CAUTION: To properly ventilate the system, you must provide at least 30.5 cm (12 inches) of
clearance at the front and back of the computer.
IMPORTANT: Any indications of component replacement or printed wiring board modifications may void
any warranty.
Rack Stability
CAUTION: This unit is designed to be electrically grounded. To ensure proper operation, plug
the AC power cord into a properly grounded (earthed) AC outlet only.
WARNING: To reduce the risk of personal injury or damage to the equipment, be sure that:
■ The leveling jacks are extended to the floor.
■ The full weight of the rack rests on the leveling jacks.
■ The stabilizing feet are attached to the rack if it is a single-rack installation.
■ The racks are coupled together in multiple rack installations.
■ Only one component is extended at a time. A rack may become unstable if more than one
component is extended for any reason.

Electrostatic Discharge Information
A discharge of static electricity can damage static-sensitive devices or microcircuitry. Proper
packaging and grounding techniques are necessary precautions to prevent damage. To prevent
electrostatic damage, observe the following precautions:
■ Transport products in static-safe containers such as conductive tubes, bags, or boxes.
■ Keep electrostatic-sensitive parts in their containers until they arrive at static-free stations.
■ Cover workstations with approved static-dissipating material. Provide a wrist strap
connected to the work surface and properly grounded (earthed) tools and equipment.
■ Keep work area free of nonconductive materials such as ordinary plastic assembly aids
and foam packing.
■ Make sure you are properly grounded (earthed) when touching a static-sensitive
component or assembly.
■ Avoid touching pins, leads, or circuitry.
■ Always place drives PCB assembly-side down.
■ Use nonconductive field service tools.

2-4 Compaq ProLiant ML570 Maintenance and Service Guide
Preparation Procedures
The system power in the ProLiant ML570 server does not completely power down with the
front panel Power On/Standby switch. The switch toggles between On and Standby, rather than
On and Off. The Standby position removes power from most electronics and the drives, but
portions of the power supply and some internal circuitry remain active. To completely remove
all power from the system, you must disconnect all power cords from the server. For more
information about removing power from the system, see “Powering Down the Server” later in
this chapter. See “Server Warnings and Precautions” later in this chapter for further safety
information.
IMPORTANT: Before beginning to remove any serviceable part, determine whether the part is
hot-pluggable or non-hot-pluggable. Hot-pluggable devices in the ProLiant ML570 server include SCSI
hard drives, fans, and power supplies.
Hot-Pluggable Parts
If the part is hot-pluggable, do not perform a power shutdown of the server. The access panel
can be removed without causing system shutdown. Hot-pluggable devices in the
ProLiant ML570 server includes Wide Ultra2 and Ultra3 SCSI hard drives, some expansion
boards, fans, and power supplies.
IMPORTANT: It is not necessary to power down the server to replace hot-pluggable devices such as
power supplies, fans, or PCI Hot Plug boards when they are not in active use.
Non-Hot-Pluggable Parts
If the part is non-hot-pluggable, the server must be shut down. Non-hot-pluggable parts include

Hot-Plug Hard Drives
The following guidelines are to be noted when removing and replacing hot-plug hard drives:
■ Never remove a hot-plug hard drive if the LED icon is green. If several drives are used,
the system boot drive should be installed in the lowest-numbered bay.
■ Never remove more than one hard drive at a time. If the server is set in an array
configuration, and a hard drive is replaced, the controller uses data from the other drives in
the array to reconstruct data on the replacement drive. If more than one hard drive is
removed, a complete data set is not available to reconstruct data on the
replacement drive(s).
■ Never remove a working hard drive when another drive has been marked as failed by the
controller. Permanent data loss occurs. Hard drives that have been failed by the controller
are indicated by the amber drive failure LED icon on the drive tray.
■ Never remove a drive while another drive is being rebuilt. A drive online LED icon
flashes green when it is being rebuilt. A replaced drive is restored from data stored on the
other drives.

servers running Microsoft Windows NT
or Novell NetWare.
If a significant change occurs between
data gathering intervals, previous
information is marked, and the survey
text file is overwritten to reflect the
latest configuration and changes since
last configuration. This allows a
historical record of change events for
server hardware and software.
Diagnostics and utilities are located on a
partition on the hard drive and must be
accessed when a system configuration
error is detected during Power-On
Self-Test (POST). Compaq Diagnostics
software is also available on the Compaq
SmartStart™ and Support Software CD.
A Diagnostics diskette can be created
from the SmartStart and Support
Software CD, and Diagnostics run from

System
Configuration Utility
(SCU)
Utility to easily configure the hardware
installed in or connected to the server.
Specifically, it can:
■ Resolve resource conflicts in areas
such as memory, port addresses,
and interrupts (IRQs)
■ Automatically configure PCI boards
■ Manage installation of processor
upgrades, and mass storage
devices such as hard drives, tape
drives, and diskette drives
■ Store configuration information in
nonvolatile memory
■ Assist in installation of an operating
system
■ Assist in running diagnostic tools
such as Test and INSPECT
■ Assist in reconfiguring a server that
cannot otherwise be restored
If the server has a bootable CD-ROM
drive, run Compaq System Configuration
Utility directly from the Support
Software CD supplied with the Compaq
Smart Array Controller Option Kit, or
SmartStart and the Support Software CD
supplied with server. Use the CD supplied
for the latest version.
If the server does not have a bootable
CD-ROM drive, create diskettes with
latest version of the System
Configuration Utility from the Support
Software CD, or the SmartStart and
Support Software CD.
Page 81
3-4 Compaq ProLiant ML570 Maintenance and Service Guide
Default Configuration
When the system is first powered up, the system ROM detects the unconfigured state of the
hardware and provides default configuration settings for most devices. By providing this
initialization, the system can run Diagnostics and other software applications before running the
normal SmartStart and System Configuration programs.
Default Configuration Messages
IMPORTANT: If you chose to format and partition the boot drive before running SmartStart and the
System Configuration programs, this action prohibits creating a System Partition and the offline remote
management features that it provides. If a System Configuration, Diagnostics, or SmartStart and Support
Software CD is in the CD-ROM drive prior to powering up the server, the system ROM powers up to
that utility.
If the system ROM does not detect one of those CDs, you are prompted for the intended
operating system. The system restarts if any operating system-dependent configurations have
changed with the new operating system selection. If the selected operating system-dependent
configurations are the same as the current configurations, the system starts normally. If you
enter a wrong choice, on subsequent restarts you may change the operating system.
INSPECT
INSPECT provides configuration information such as the contents of the operating system (OS)
startup files, current memory configuration, ROM version, and Integrated Management Log
(IML) information. It operates with MS-DOS and in the MS-DOS emulation mode of MS OS/2.
Running INSPECT
1. Power down the server, then power up, and then press F10 when the cursor displays in the
upper right corner of the screen.
2. At the main menu, select Diagnostics and Utilities.
3. Press Enter.
4. Select Inspect Computer, and then press Enter.
NOTE: If Diagnostics is not installed on the hard drive, System Configuration prompts you to insert the
Diagnostics diskette into drive A.
5. Follow the instructions. The first time the INSPECT displays, select Entire System, and
then press Enter.
Printing the INSPECT Listing
Select Print on the INSPECT screen to print a copy of the INSPECT listing. Keep a copy of the
listing with each server for later reference.

Power-On Self-Test
Power-On Self-Test (POST) is a series of diagnostic tests that automatically run on Compaq
computers when the system is powered up. POST checks the following assemblies to ensure that
the computer system is functioning properly:
■ System ROM
■ Keyboard
■ Power supply
■ System board
■ Memory
■ Memory expansion boards
■ Controllers
■ Diskette drives
■ Hard drives
■ Fans

POST Error Messages
If POST finds an error in the system, an error condition is indicated by an audible and visual
message. If an error code displays on the screen during POST or after resetting the system, use
the instructions in the POST Error Messages table (Table 3-2).
NOTE: Many of the actions listed require you to run Diagnostics or the System Configuration Utility.
Steps for running these utilities are provided following the POST Error Messages tables.
The Recommended Action column in Table 3-2 lists the steps necessary to correct the problem.
After completing each step, run the Diagnostics program to verify whether the error condition
has been corrected. If the error code is redisplayed, perform the next step, and then run the
Diagnostics program again. Follow this procedure until Diagnostics no longer detects an error
condition.

the utility prompts you to test, inspect, upgrade, and diagnose the server.
Diagnostics and Utilities are located on the system partition on the hard drive and must be
accessed when a system configuration error is detected during the Power-On Self-Test (POST).
Diagnostics software is also available on the SmartStart and Support Software CD. You can
create a Diagnostics diskette from the SmartStart and Support Software CD and run Diagnostics
from diskette. See the “Running the Utilities from Diskette” procedure earlier in this chapter.
The following options are available from the Diagnostics and Utilities menu:
■ Test Computer
■ Inspect Computer
■ Upgrade Firmware
■ Remote Utilities
■ Diagnose Drive Array
Diagnostic error codes are generated when the Diagnostics software recognizes a problem.
These error codes help identify possible defective subassemblies.
Steps for Diagnostics
In each case, the Recommended Action column lists the steps necessary to correct the problem.
After completing each step, run the Diagnostics utility to verify that the error condition has been
corrected. If the error code is redisplayed:
1. Perform the next step listed in the table.
2. Run the Diagnostics utility program again.
3. Follow this procedure until the Diagnostics utility program no longer detects an error
condition.
