about find it?
Chapter 1
Server startup errors You are provided with step-by-step instructions on what to try
and where to go for help, for the most common problems
encountered during the initial Power-On Self-Test. The server
must complete this test each time you power up your server,
before the server can load the operating system and start
running software applications.
Chapter 1
Server installation Once your server has passed the Power-On Self-Test, you
errors may still encounter errors, such as an inability to load your
operating system. You are provided with instructions on what
to try and where to go for help, when you encounter errors
after the server completes the Power-On Self-Test.
Chapter 2
Status indicators There are several status LEDs located on the front and rear of
your server. These LEDs can communicate the current status
of varying aspects of your server components and operations,
thus aiding you in diagnosing the problem. You are provided
with an illustration of the location of each LED on your server,
as well as an explanation of uses and possible status.
Switch settings There are three switch banks in your server. Some of these Chapter 3
may need to be changed from time to time and can cause
problems if they are not set correctly, and some should not
be changed for any reason. You are provided with a list of all
switches, a description of what each setting means, and an
illustration of where each may be found inside your server.
Minimum hardware Compliance with the minimum hardware configuration for Appendix A
specifications your ProLiant ML570 server is required to power up the
server and run an operating system. This is often a good
place to start diagnosis after you have changed your
hardware configuration.
Supported operating It is possible to encounter errors when using an operating Appendix A
systems system that is not compatible with your server. Look here for
the name and version of each operating system supported for
your server.

Chapter
Server Startup and Operation Errors
This chapter provides step-by-step instructions on what to try and where to go
for help for the most common problems encountered during the initial
Power-On Self-Test. The server must complete this test each time you power
up your server, before the server can load the operating system and start
running software applications.
When the Server Does Not Start
Complete these steps if the server does not start.
1. Verify that the computer and monitor are plugged into a working outlet.
2. Make sure your power source is working properly.
G Check status using the Power On/Standby LED. See Chapter 2 for
the location of the system status LEDs.
G Was the Power On/Standby switch pressed firmly?
Refer to the "Power Source" section in the Compaq Servers
Troubleshooting Guide for details on what else to check.
3. Make sure the power supplies are working properly.
G Check status using the power supply diagnostic LEDs. See the
"Power Supply Diagnostic LED Indicators" section in Chapter 2 for
the location of these LEDs, and an explanation of statuses.
G Also refer to the "Power Source" section in the Compaq Servers
Troubleshooting Guide.

4. If the system does not complete the Power-On Self-Test (POST) or start
loading an operating system, refer to the "General Loose Connections"
section in the Compaq Servers Troubleshooting Guide.
5. If the server is power cycling, verify that the system is not rebooting due
to an Automatic Server Recovery-2 (ASR-2) reboot caused by another
problem.
In the Compaq Servers Troubleshooting Guide, refer to:
G "Automatic Server Recovery-2 (ASR-2)"
G "System Short" for other reasons for power cycling
NOTE: ASR-2 can be enabled to restart your server, automatically loading the operating
system. Should a critical error occur, ASR-2 will log the error in the Integrated
Management Log (IML) and restart the server. The system ROM will then page the
designated administrator and execute the normal restart process.
6. Restart the server, and see "Normal Power-up Sequence," immediately
following, to verify that your system starts correctly.
7. If this does not solve the problem, continue with the following section
"Diagnosis Steps."

CAUTION: Opening the access panel for an extended period of time when the
server is on interferes with proper airflow and will cause a temperature
violation. It is appropriate to open the server access panel briefly during server
operation to view the Internal Diagnostic Display (IDD) during problem diagnosis
or to replace a redundant hot-plug power supply or hot-plug fan. If you feel that
you will need to keep the access panel open for an extended period of time,
prior to opening the unit:
1. Close all applications.
2. Bring down the operating system.
3. Press the Power On/Standby switch to place the server in standby mode.

CAUTION: Opening the access panel for an extended period of time when the
server is on interferes with proper airflow and will cause a temperature
violation. It is appropriate to open the server access panel briefly during server
operation to view the Internal Diagnostic Display (IDD) during problem diagnosis
or to replace a redundant hot-plug power supply or hot-plug fan. If you feel that
you will need to keep the access panel open for an extended period of time,
prior to opening the unit:
1. Close all applications.
2. Bring down the operating system.
3. Press the Power On/Standby switch to place the server in standby mode.
Internal Diagnostic Display (IDD)
The Internal Diagnostic Display (IDD) indicates the failure of a memory

Chapter
Switch Settings
When a component is added, removed or not functioning properly, the server
switch settings must be checked. In some cases the switch settings must be
reconfigured for the server to recognize these changes. If the system
configuration is incorrect, your server may not work properly and you may
receive error messages on the screen. Setting and verifying the system board
switches is part of the troubleshooting process.
The ProLiant ML570 server has three switch banks:
I SW1, a six-position system maintenance switch on the peripheral board
I SW4, a four-position processor configuration switch on the system
board
I SW6, a four position service switch on the system board
This chapter provides figures and tables to show the locations, positions,
functions, and settings for these switches.
System Maintenance Switch (SW1)
The system maintenance switch (SW1) is used to:
I Disable the embedded video in the system.
I Lock system nonvolatile RAM from accepting configuration changes.
I Designate rack-mount or tower configuration.
I Enable or disable the diskette boot option.

CAUTION: When maintenance mode is turned on (the maintenance switch is set to on/closed) and the

Enabling ROMPaq Disaster Recovery Mode
A corrupted system ROM will require that you re-create the ROM BIOS by
using the ROM flash. This can be accomplished only when the system is in
disaster recovery mode. Set configuration switches 1, 4, 5, and 6 on the system
maintenance switch block to on to enable disaster mode.
IMPORTANT: Prior to performing this operation, refer to the Compaq Servers
Troubleshooting Guide for complete instructions on disaster recovery.
