FOR PROPER OPERATION

Observe the following notes for successful operation of the server. Use of the server ignoring these notes will cause
malfunctions or failures of the server.

Install the server in a place that meets requirements for successful operation. For details, see Chapter 3,
"Setting Up Your Server."

Do not delete the hard disk partition exclusively provided for maintenance of the server although it may
appear on the operating system.

Make sure to power off the server before connecting or disconnecting cables between the server and
peripheral devices.

Verify that the access lamp on the server is unlit before turning off the server or ejecting the floppy disk.

The server management logic on your system board monitors and logs system voltage changes. When
plugging the power cord to the system, you may experience 10 seconds delay from the time you press the
POWER switch on the front panel. This is normal system operation and is required by the server management
logic.

When you have just turned off the server, wait at least 30 seconds before turning it back on.

Do not turn off the server until characters following our logo appear on the screen.

Turn off the power and unplug the power cord from the outlet before relocating the server.

Some software includes a command to eject the CD-ROM tray. Make sure that the front door is opened before
running the command. Running this command with the front door closed may cause the CD-ROM tray or the
media to hit against the front door, resulting in a failure of the server.

Clean the server on a regular basis. (See Chapter 7 for cleaning.) Regular cleaning proactively prevents
various failures of the server.

Lightning may cause a momentary voltage drop. To prevent this problem, it is recommended to use an
uninterruptible power supply unit.

Check and adjust the system clock before the operation if any of the following conditions is applicable.

–

After transport of the server

–

After storage of the server

–

After the server is entered into the pause state under the environmental condition enduring the server
operation (temperature: 10°C to 35°C, humidity: 20% to 80%)

Check the system clock at the rough rate of once per month. When the system clock is installed in a system
requiring high time precision, it is recommended to use a time server (NTP server).
If the system clock is remarkably delayed or advanced as the passage of time in spite of adjustment, contact
your service representative to ask for maintenance.

Store the unit under the storage condition (temperature: -10°C to 55°C, humidity: 20% to 80%, without
condensation) to allow built-in devices and the unit to operate correctly in the next operation.

Make sure to use optional devices supported by the server. Some non-supported devices may be physically
installed/connected but cause failures of the server as well as malfunctions of the server.

We recommend you use our genuine products. Some third-party products claim that they support the server.
However, repair of the server due to a failure or damage resulting from use of such third-party products will
be charged.
