diagnostics. Refer to Chapter 3, “Dia gnostic Tools,” for more information.

Safety Considerations

Electrostatic Discharge Information

2

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. Use a wrist strap connected
to the work surface and properly grounded tools and equipment.

•

Keep the work area free of nonconductive materials such as ordinary plastic assembly
aids and foam packing.

•

CAUTION: Always match the local I/O cable labeled with the I/O icon to the I/O port also
labeled with the I/O icon. The Diagnostic cable and port have no labels. Mismatched cables
prevent proper connection.

Use either the diagnostic cable or the local I/O cable to perform some server blade
configuration and diagnostic procedures. Depending on the model, the server blade will have
either a diagnostic port or an I/O port. The I/O port only accepts the local I/O cable, and the
diagnostic port only accepts the diagnostic cable. If the server blade has an I/O icon next to
the I/O port on the front of the server blade, use the local I/O cable. If the port has no icon,

LEDs provide activity, online, and fault status for each corresponding drive when configured
as a part of an array and attached to a powered-on Smart Array controller. Their behavior
may vary depending on the status of other drives in the array. Use Figure 4-7 and Table 4-5 to
identify LED locations and functions.

Use the following sections to identify the locations and functions of push-button and system
switches.

Buttons

Use the “Power On/Standby Button” section to identify push-button switches on the system
hardware.

Power On/Standby Button

Setting the server blade Power On/Standby button to the standby position removes power
from most areas of the server blade. This process may take 30 seconds, during which time
some internal circuitry remains active.

Use Figure 4-8 to identify the button location.

NMI Switch

Crash dump analysis is an essential part of eliminating reliability problems such as hangs or
crashes in operating systems, device drivers, and applications. Crashes can freeze a system,
requiring you to do a hard reset. Resetting the system erases any information that supports
root cause analysis.

Systems running Microsoft Windows 2000 experience a blue screen trap when the
operating system crashes. When this happens, Microsoft recommends that system
administrators perform an NMI event by pressing a dump switch. The NMI event allows a
hung system to become responsive.

The ProLiant BL20p G2 server blade is equipped with an NMI switch that, when pushed,
performs a memory dump before performing a hard reset. The NMI switch is for use by
trained service personnel only.

System Configuration Switch Procedures

When you perform troubleshooting steps, this guide may instruct you to perform the
following procedures:

• • Clear the system configuration.

Access the redundant ROM.

To complete these procedures, you must change physical settings on the system configuration
switch (SW1).

Clearing the System Configuration

To clear the system configuration:

1. Power down the server blade:
— Press the Power On/Standby button on the front of the server blade.
— Use the virtual power button feature in the iLO remote console.

2. Disconnect the server blade from all power sources:
— Remove the server blade from the enclosure and set it on a flat, level surface.
— Disconnect the server blade from the diagnostic station.

3. Remove the access panel. Refer to the “ Access Panel” section in Chapter 2, “Removal
and Replacement Procedures.”

4. Change position 6 of SW4 to on.

5. Install the access panel. Refer to the “Acc ess Panel” section in Chapter 2, “Remo val and
Replacement Procedures.”

6. Connect the server blade to system power:
— Install the server blade in the enclosure.
— Connect the server blade to the diagnostic station.

7. Power up the server blade:

— Press the Power On/Standby button on the front of the server blade.
— Use the virtual power button feature in the iLO remote console.

8. Wait for the POST message that prompts you to change the switch setting:

Maintenance switch detected in the "On" position.
Power off the server and turn switch to the "Off" position.

9. Repeat steps 1 through 3.

10. Change position 6 of SW4 to off.

11. Repeat steps 5 through 7.

IMPORTANT: When the server blade boots after NVRAM is cleared, a delay of up to 2 minutes is
normal. During this delay, the system appears non-functional. Do not attempt any procedures during the
delay.

— Disconnect the server blade from the diagnostic station.

3. Remove the access panel. Refer to the “A ccess Panel” section in Chapter 2, “Removal
and Replacement Procedures.”

4. Change positions 1, 5, and 6 of SW4 to on.

5. Install the access panel. Refer to the “Acce ss Panel” section in Chapter 2, “Removal and
Replacement Procedures.”

6. Connect the server blade to system power:
— Install the server blade in the enclosure.
— Connect the server blade to the diagnostic station.

7. Power up the server blade:
— Press the Power On/Standby button on the front of the server blade.
— Use the virtual power button feature in the iLO remote console.

8. As soon as the server blade powers up, it emits two beeps.

9. Repeat steps 1 through 3.

10. Change positions 1, 5, and 6 of SW4 to off.

11. Repeat steps 5 through 7.

If both the current and backup versions of the ROM are corrupt, you must return the system
board for a service replacement. For spare part numbers, refer to Chapter 1, “Illustrated Parts
Catalog.”
