Overview of Express5800/320Ma 3.2
The following sections provide an overview of Express5800/320Ma 3.2 GHz, 3.6 GHz,
and Dual-Core systems:
• “System Design” on page 1-1
• “System Features” on page 1-2
• “System Components and CRUs” on page 1-3
System Design
The design of Express5800/320Ma 3.2 GHz, 3.6 GHz, and Dual-Core systems
includes the following:
• Fault-tolerant architecture
Critical components are redundant (duplexed). If one duplexed component fails,
the system continues to operate with the redundant component in simplex mode
until you can remove an enclosure or the system from service to replace the failed
component.
GHz, 3.6 GHz, and Dual-Core Systems
1-
• Customer-replaceable units (CRUs), parts that you can replace on-site with
minimal training or tools
Some CRUs are hot-pluggable. You can replace them without interrupting system
operation.
• Fault-hardened drivers that enhance application reliability and availability
• Optional support by the ActiveService Network (ASN)
This support provides remote service and incident management of the system by
NEC Technical Support, or your authorized service representative. Connectivity to
the ASN is through a pair of remote management adapters — Virtual Technician
Modules (VTMs) — and a modem, only through a modem, or over the Internet.

See the following for information about the basic operation of Express5800/320Ma 3.2
GHz, 3.6 GHz, and Dual-Core systems:
• “Standby Power” on page 2-1
• “System Power” on page 2-1
• “Starting Up the System” on page 2-2
• “Shutting Down the System” on page 2-2
• “Fan Speed” on page 2-3
See the vendor documentation for information about operating optional equipment.
Standby Power
When one or both of the system power cords are connected to live AC power outlets,
low-level standby power is present in the system. Standby power enables the primary
BMC controller to monitor the status of system components, even when the system
power is off.
Hardware Operation
2-
Standby power also allows for continuous operation of the VTMs and the modem
assembly; therefore, while the system power is off, administrators can still connect to
the system through the VTMs or the modem assembly to diagnose problems, or to turn
system power on and off from a remote location.
Standby power remains present even after the system has been powered down. To
remove power to the standby devices, remove the power cords.
System Power
Express5800/320Ma 3.2 GHz, 3.6 GHz, and Dual-Core systems have two power
buttons, one on each CPU- I ⁄ O enclosure. Because only one enclosure is the primary
or active enclosure, only one power button is the active button: the one whose LED is
lit (assuming the system has standby power). This button, which you press to start the
system, indicates the primary CPU- I⁄ Oenclosure.
Hardware Operation 2-1
Starting Up the System
The system power button is located on the front of the system and functions as follows:
• If the system power is off and standby power is on, pressing the power button turns
the system on and boots the operating system.
• If the system power is on and the operating system or BIOS is starting, stopping,
or running, pressing the power button for several seconds shuts down the system
in the same way as the shut down option from Windows. (Standby power remains
on.)
• If the operating system hangs or a hardware failure occurs, pressing the power
button for several seconds shuts down the system power. (Standby power remains
on.)
NOTE
If you do not want to risk loss of data that might occur from
this action, and if the system contains VTM adapters, you
can attempt less severe actions to restart the system. See
the Express5800/320Ma Virtual Technician Module
User’s Guide for more information.
Starting Up the System
Make sure the system power cords are plugged into live AC outlets.
To boot a system and start the operating system
1. Turn on the monitor and any other peripheral devices.
2. On the CPU- I⁄ O enclosure whose power-button LED is lit, lift the plastic cover that
shields the system power button (number 2 in Figure 1-2) and press the button.
Shutting Down the System
Exit from all applications before shutting down a system.
To shut down a system
1. Click the Start button on the Windows desktop, and then click Shut Down.
2. In the Shut Down Windows dialog box, select Shut Down in the drop-down list,
and then click OK.
3. Turn off power to the monitor and any peripheral devices.
2-2 Express5800/320Ma: Operation and Maintenance Guide
Fan Speed
You might notice fan-speed increases in high-temperature environments, during high
system activity periods, or while performing an IPL (loading the operating system
software), shutting down the system, or restarting Windows. The increase in fan speed
ensures adequate cooling under these conditions and is normal behavior.
Fan Speed
NOTE
The system’s standby devices have power even after the
system has been powered down. To remove power to the
standby devices, you must remove the power cords.

• “Using the Dump Button to Create a Dump File” on page 3-15
System LEDs
System LEDs are located on the front and rear of each CPU-I ⁄ O enclosure.
The LEDs can be single-color or bicolor:
• Single-color LEDs are green, amber, or white.
• Bicolor LEDs can be green or amber.
Troubleshooting the Hardware
3-
At any time, the LEDs can also have one of three different states:
• Unlit, or OFF
• Steady on, or ON
• Blinking
You can determine the state of a particular component by interpreting the combinations
of LED colors and states. For example, you can determine if system components are
operating in duplex or simplex mode. Duplex mode means that the components are
partnered and the partner is operating properly. Simplex mode means that the partner
failed or was removed.
Ta bl e 3- 1 describes the general meaning of the LED colors and states.

For information about LEDs in optional components, see the vendor documentation.
3-2 Express5800/320Ma: Operation and Maintenance Guide
CPU-I/O Enclosure Status LEDs
Each CPU- I ⁄ O enclosure contains three LEDs that describe the status of the
components in the enclosure, including the CPU, BMC, VTM, PCI adapters, and SATA
disk drives. These LEDs, which are located on the front and rear of each enclosure, are
green, amber, and white. The CPU-I ⁄ O enclosure status LEDs are shown in
Figure 3-1 and described in Tab le 3- 2.
NOTE
During the boot process, the BMC verifies that all devices
in the CPU- I ⁄ O enclosures are present and performing
normally before the BMC activates that enclosure. If a
component has failed, the BMC removes power from that
enclosure. As a result, the LEDs on an enclosure might
turn on briefly and then turn off, or the LEDs might not turn
on at all, indicating a failed component of the enclosure.

System LEDs
If system is on (steady green LEDs), removing the enclosure will crash
the system because no partner is available.
If system power is off (green blinking LED), either the BMC or the VTM is
operating in simplex mode. If you remove the enclosure, you cannot
power the system on, or access the system remotely.
Action: Return the offline partner component to service.

Action: Verify that the drive is properly installed. Verify the connection
by removing and replacing the drive.
Refer to ftSMC for information about the failure and attempt to correct
the failure in the operating system. For help in interpreting the
information displayed in ftSMC, see the Help for ftSMC and

– If the drive is part of a Rapid Disk Resync (RDR) drive pair, the
partner drive is unavailable.
Action: Reinsert the partner drive to restore duplex operation.
Verify that the partner drive is functioning normally.
– If the drive is not part of an RDR pair, a non-mirrored volume
exists on the drive. Or, a mirrored volume exists on the drive, but its
partner volume is unavailable.
Action: If the drive contains a mirrored volume, reinsert the drive
that contains its partner volume to restore duplex operation. If the
drive is not mirrored, consider creating an RDR drive pair or
another type of mirrored set to increase fault tolerance.
– If the drive is part of an RDR drive pair or it contains part of a
mirrored volume pair, the drive or volume is resynchronizing.
Action: Wait for the process to complete.
For information about RDR and mirrored volumes, see the
Express5800/320Ma: System Administrator’s Guide.
See “General Disk Drive Problems and Solutions” on page 3-12 for additional
troubleshooting information.
