1-20 Precautions for Use

Advice for Your Health

Prolonged use of a computer may affect your health. Keep in mind the following to reduce stresses on your body:

Sit in a good posture

Sit on your chair with your back straight. If the desk height is appropriate, you will slightly look down at the screen and your forearms will be parallel to the floor. This “good” work posture can minimize muscle tension caused by sedentary work.

If you sit in a “bad” posture—for example, sit round-shouldered or with you face too close to the display—you may easily suffer fatigue or have your eyesight affected.

Adjust the installation angle of Display

Most types of displays allow you to adjust the angle vertically and horizontally. This adjustment is very important to prevent the reflection of light as well as to make the screen more comfortable to see. Without this adjustment, it is difficult to maintain a “good” work posture and may get tired soon. Be sure to adjust the angle before using the display.

Adjust Brightness and Contrast

Displays allow you to adjust brightness and contrast. Optimum brightness and contrast vary depending on the individual, age, brightness of the room, etc; you need to make an adjustment accordingly. If the screen is too bright or too dark, it is bad for your eyes.

Adjust the installation angle of Keyboard

Some types of keyboards allow you to adjust the angle. If you adjust the angle to make the keyboard more comfortable to use, you can greatly reduce stresses on your shoulders, arms, and fingers.

Clean the Equipment

Cleanliness of the equipment is very important not only for reasons of appearance but also from the viewpoints of function and safety. Especially, you need to regularly clean the display, which gets unclear due to the accumulation of dirt.

Take a break when you get tired

If you feel tired, you are recommended to refresh yourself by taking a short break or doing a light exercise.

Standard product

NEC Express5800/ft series is a highly fault-tolerant Windows server that achieves continuous computing operations, data storage mirror, and continuous network connection. It allows you to run Windows Server 2003-based applications.

NEC Express5800/ft series achieves continuous computing operations for the Windows server and server-based applications with its redundant CPU processing and redundant memory. It assures data redundancy through duplication of server data on an independent storage system. These features eliminate server downtime that is usually caused by network disconnection or trouble with the I/O controller, Eth e rnet ada pt e r o r disk d ri ve, and su pp ort o per ati on of the network and server applications continuously. While being transparent to application software, NEC Express5800/ft series achieves high fault-tolerance.

NEC Express5800/ft series detects status changes, errors and other events and notifies the Windows Event Log of these events. If you use an alarm notification tool, yo u can configure NEC Express5800/ft series to notify you when certain events occur.

NEC ESMPRO is installed on the system as a server management solution. NEC ESMPRO, a GUI-based management tool, allows you to monitor, view, and configure NEC Express5800/ft series. This tool also supports both local and remote management of NEC Express5800/ft series.

2-4 General Description

NEC Express5800/ft series mainly provides the following advantages:

 Highly fault-tolerant processing and I/O subsystems

NEC Express5800/ft series use redundant hardware and software to assure server operation even if one module suffers trouble with its processor, me mory, I/O (including trouble related to the I/O controller), disk drive, or Ethernet adapter.

 Continuous network connection

NEC Express5800/ft series maintains continuous network connection by detecting any trouble with the network adapter, connection, etc. If trouble occurs, the standby network connection will take over all network traffic processing and thus securely maintain the network system connection of NEC Express5800/ft series without losing network traffic or client connection.

 Support of multiple network connections

Since NEC Express5800/ft series can support multiple Ethernet connections, you can add network redundant control or network tr affic cont rol.

 Industry standard hardware platform

NEC Express5800/ft series uses IA (Intel Architecture)-based system hardware.

 No need to modify applications

You can run Windows Server 2003-compliant applications on NEC Express5800/ft series. Thus, unlike other highly fault-tolerant products, special API or scripts are not necessary.

 Automatic mi rroring

NEC Express5800/ft series automatically maintains data as the current data.

 Automatic detection and notification of faults

NEC Express5800/ft series detects and sorts out all events such as general status changes and faults, and notifies Windows Event Log of these events.

 Transparent migration

NEC Express5800/ft series constantly monitors events. If trouble occurs on NEC Express5800/ft series’ server module, it will transparently use a redundant module of the failed module. This feature maintains data and user access without losing application service.

 Automatic reconfiguration

When the failed module restarts after the trouble is corrected, NEC Express5800/ft series will perform reconfiguration automatically, and if necessary, resynchronize the affected modules. Reconfiguration can include CPU processing (e.g., CPU memory), server's operating system (and related applications), and system data stored on the hard disks. In most cases, NEC Express5800/ft series automatically restores redundancy of the server modules after recovery.

General Description 2-5

 Local and remote management

NEC Express5800/ft series uses NEC ESMPRO as a server management tool. This tool uses a GUI that enables monitoring and setting of NEC Express5800/ft series. NEC ESMPRO can be used both locally and remotely on work station PCs or server PCs.

 Event notification function

When trouble or other events are detected on NEC Express5800/ft series, they will be notified to Windows Event Log and saved. Therefore, you can view the log items locally or remotely by a usual Windows procedure. Since an NEC Express5800/ft series events use unique IDs, they are easy to distinguish.

 In-service repairing

You can repair or replace a failed module even if NEC Express5800/ft series is operating.

 Partition structure

On this product, the first logical drive will be in the following state when the setup by NEC EXPRESSBUILDER is complete:

The system will be powered off automatically. (No te: the POWER LED on the primary side will remain illuminating when AC power is supplied.)

2. Power off all peripheral devices.

2-32 General Description

POST Check

POST (power-on self test) is a self-test function stored on the motherboard of NEC Express5800/ft series.

When you power on the server, POST will start automatically to check the motherboard, ECC memory modules, CPU modules, keyboard, mouse, etc. It also shows startup messages for various BIOS setup utilities.

According to the factory default settings, the “NEC” logo appears on the display while POST is being performed. (To view POST’s details, press

Esc.)

TIPS:

 You can view POST details from the beginning without the need to press Esc when the

BIOS menu is displayed: select [System Configuration] - [Advanced], and set [Boot-time Diagnostic Screen] to "Enabled" (see Chapter 4).

 You can view the test items and details from a management PC where NEC ESMPRO

Manager or NEC MWA is installed.

You don't always need to check POST details. You will need to check messages when:

 You install a new NEC Express5800/ft series.  A failure is suspected.  You hear several beeps between the time of the power-on and OS start-up.  The display unit or the LCD* shows an error message.

*For details, see “Error Messages on LCD” in Chapter 7.

TIPS: Although there is no LCD on the front of NEC Express5800/ft series, you

can check error messages using NEC MWA or NEC ESMPRO Manager. For details, see Chapter 7.

General Description 2-33

Flow of POST

This section walks you through how POST is performed.

1. When you power on the system, one selected CPU/PCI module will start up.

POST will be performed on this selected CPU/PCI module.

2. Memory check starts.

A message appears at the upper left of the screen to show that the basic and expanded memories are being counted. The memory check may take a few minutes to complete depending on the server’s memory size. Likewise, it may take about one minute for the screen to appear when the server is rebooted.

Note that if you have replaced the PCI module, the server will perform a reset of the MAC address, then reboot itself before the memory check.

3. The server starts processor check, IO check, and initialization.

Several messages appear: they show the ID of the selected CPU/PCI modules, in formation on the processor, detection of the keyboard and mouse, etc.

4. A message appears at the lower left of the screen, prompting for startup of the BIOS setup

utility “SETUP.”

Press <F2> to enter SETUP

You will need to start it when you want modify the configuration for using the server. Unless this message appears together with an error message, you don't need to start the utility to modify the configuration. (If you wait for a few seconds, POST will go on automatically.)

To start the SETUP utility, press parameter functions, see the section of BIOS setup.

When SETUP is completed, the server will reboot itself automatically and perform POST.

F2 while the above message is displayed. For setting and

5. A message appears prompting for startup of SCSI BIOS setup utility.

When a built-in SCSI controller is detected, a message will appear prompting for startup of SCSI BIOS setup utility. (If you wait for a few seconds, POST will go on automatically.)

If you press functions, see the section on SCSI setup.

You will need to use this utility, for example, when you have changed the server’s internal SCSI device connections. However, you usually don’t need to use it.

When SETUP is complete, the server will reboot automatically and perform POST again. If multiple SCSI controller boards are mounted on the PCI bus, the SCSI BIOS startup

message will appear for these boards in numerical order (PCI #1, PCI #2, PCI #3…).

Ctrl + Q, the SCSI BIOS setup utility will start. For setting and parameter

6. The screen shows SCSI ID numbers used by the connected SCSI devices.

2-34 General Description

7. Upon completion of POST, the password entry screen appears prior to OS startup.

The password entry screen will appear after the normal termination of POST only if you have set a password in the BIOS setup utility “SETUP.”

You can enter a password up to three times. If you enter an incorrect password three times, the startup will be unsuccessful. In this case, turn off the power and then turn it on again after waiting 30 seconds to boot the server.

IMPORTANT: Do not set a password before installing the OS.

8. Upon completion of POST, the OS will start up.

Behavior at Occurrence of Error

If POST or OS startup does not finish normally, the server will reboot itself automatically. At the time of reboot, it will select the other CPU/PCI module and run POST or OS startup. In this manner, the server retries POST or OS startup with different combinations of CPU/PCI

modules. If POST does not finish normally with any combinations, the server will stop with the state of DC OFF .

While performing retries, the server displays or registers the error types.

For details of error messages, see Chapter 7 “Troubleshooting.”

POST Error Messages

When the server detects an error during POST, it will notify you of the occurrence in the following manners:

 Displays an error message on the display unit.  Displays an error message on the LCD*.  Makes a beepin g sound.

*For details, see “Error Messages on LCD” in Chapter 7.

These notification methods are described in “POST Error Messages” in Chapter 7.

IMPORTANT: Before you contact your sales agent, write do wn the error messages and

patterns of the beeping sound. They will serve as helpful information at the time of maintenance.

General Description 2-35

Floppy Disk Drive

A USB floppy disk drive is attached to the main unit. It allows you to read and write (save) data using floppy disks.

The USB floppy disk drive accepts the following types of floppy disks:

 2HD floppy disk (1.44MB)  2DD floppy disk (720KB)

Drive letter of floppy disk drive

The drive letter will change when the primary PCI module is switched to the standby PCI module while the Windows operating system is in operation. The drive letter of the floppy disk will be determined as follows:

“A” will be assigned to the floppy disk drive for the PCI module that is operating as the primary PCI module during Windows operating system boot-up. “B” will be assigned to the floppy disk drive for the standby PCI module.

Ex) If a floppy disk drive was connected for the first time while the primary PCI module is group 1. Primary PCI module PCI module (f or gro u p 1): A drive PCI module (for group 2): B drive

IMPORTANT: In the event that the active PCI module switches to the standby PCI module

due to a failure while the system is in operation, the floppy disk drive letter will change at the point PCI module switches to the standby module.

2-36 General Description

Insert/Remove Floppy Disk

Before inserting a floppy disk into the drive, make sure that NEC Express5800/ft series is on and that the drive’s USB cable is connected to the USB connector at the back of the server.

Insert a floppy disk into the drive firmly with the label side up and its protective shutter facing the drive.

TIPS:

 If you insert an unformatted disk, you will see a message that the disk cannot be read or that

needs formatting. To format a floppy disk, see your OS manual.

 If you power on or restart NEC Express5800/ft series with a floppy disk left in the driv e, the

server will access the floppy disk to start the system. Unless a system exits on the FD, the server will be unable to start.

To remove a floppy disk from the drive, press the eject butto n.

TIPS: Before removing a floppy disk, make sure that the access LED is off. If you eject a floppy

Disk Operations Using the RDR (Rapid Disk Resync) Function

RDR (Rapid Disk Resync)

Models supporting the RDR function secure reliability by mak ing disks duplex ed per disk using the ft control software’s RDR function. Duplexing disks by the RDR function enables the disks to be resynchronized in a short period of time when their mirror has been broken due to causes such as PCI module replacement

Setting RDR to disks duplicates the disks of paired slots as shown in the figure below and Windows (ex. Disk Management and Device Manager) recognizes a paired disks as a single virtual disk.

[Paired slots]

Corresponding slots Virtual disk name given by the RDR

Utility

PCI module#1 Slot 1 Ù PCI module#2 Slot 1 PCI module#1 Slot 2 Ù PCI module#2 Slot 2 PCI module#1 Slot 3 Ù PCI module#2 Slot 3

Note: In the above table, the PCI module names correspond to the following modules:

PCI module (for Group1): PCI module#1 PCI module (for Group2): PCI module#2

[Cautions for using the RDR function]

RDR V i rtual Disk 1 RDR V i rtual Disk 2 RDR V i rtual Disk 3

1. RDR can be set only to the disks inserted into the built-in slots of NEC Express5800/ft series.

2. Be sure to specify RDR to all disks inserted to the built-in slots and make duplex settings.

3. RDR can be set only to basic disks.

If a span volume or stripe volume is needed, make settings of RDR to a basic disk and then change the disk to a dynamic disk from [Disk Management].

4. The disks to set RDR must have the same capacity and must be new or physically formatted.

(For physical format, refer to “SCSI BIOS ~ Fast!UTIL ~” in Chapter 4 “System Configuration” and perform Low-Level Format using SCSI Disk Utility.)

3-16 Windows Setup and Operation

5. The disks which RDR has been set can only be used in the system with the ft control software

ver.3.0 or later.

6. Insert or replace the HDD while the server is powered on if the RDR function is used.

If a new HDD (non-formatted HDD on Windows OS ) is inserted to the slot corr esponding to the slot with the disk you specified RDR when the server is powered off, the OS may not be able to start or the HDD mirroring may not be completed properly.

Configuring and Removing Duplexed Setting of Disks by the RDR Function

This section describes how to make disks duplex and how to remove the settings by using the RDR function. To use th e RDR function, use [RDR Utility].

6. On the left tree on [RDR Utility], right-click the disk which was inserted in the previous

step and click [Add RDR Virtual Disk].

IMPORTANT:

If the inserted disk has not been initialized on Windows, RDR is set and synchronization starts automatically, so this step is not required. Skip to the next step and check the duplex status.

7. Click [Logical Disk Information] and then [RDR Virtual Disk x](x=1,2,3) to confirm

that the synchronization is started.

IMPORTANT:

 The time required for synchronization varies depending on the partition size on

the disk. For 18GB partition, it takes about 16 minutes. When there is no partition, synchronization may be completed in a short period of time after RDR is set and the status may change to what is described in the step 8.

 The percentage changes from 0 to 25, 50, 75 depending on the synchronization

process progresses.

 If the system is rebooted during synchronization, the process cannot be

completed. Do not restart the system until the synchronization is completed.

When the [Op State: State] of [RDR Virtual Disk x](x=1,2,3) becomes [Duplex] and [Status] becomes [None], the disk synchronization is completed.

IMPORTANT:

 When a new partition is created on the disk where RDR is set, the created

partition area is synchronized automatically.

 When the disk where RDR is set is converted to a dynamic disk, the area which

has not been synchronized (the area that no partition exists) will be synchronized.

 When the system is shut down without shutting down Windows properly, for

example, by pressing the power button, the entire area of the synchronized disks will be resynchronized after the system is restarted.
