Handling Precautions - NEC EXP339 User Manual

Handling precautions

Be sure to observe the following precautions for the proper functioning of the server. Ignoring the precautions
may cause server malfunction or failure.

Do not use any cell phones and switch off them near the server. Electric waves from such devices can cause
server to malfunction.

Install the server in an appropriate place. For details, see Chapter 2 (2. Installation and Connection).

If a peripheral device is a not plug-and-play device, make sure that the server is off and unplug the power
cord before connecting/removing cables to/from the devices.

Connect the provided power cord to a 100/200 VAC outlet.

Make sure that the access LED on the server is off before turning off the power or ejecting an optical disk.

Wait for at least 30 seconds before turning on the server after turning off the server. If any Uninterruptible
Power Supply (UPS) unit is connected, set it to wait for at least 30 seconds before turning on the server after
power off.

Do not press the POWER switch to turn on the server before the STATUS LED (amber) is unlit.

Turn off the server and unplug the power cord before moving it.

Regularly clean the server to prevent various types of failure. See Chapter 1 Maintenance (2. Daily
Maintenance) in Maintenance Guide for details.

Momentary voltage drop may occur due to lightning strike. To prevent this, use of UPS is recommended.

We do not guarantee that the server's optical disk drive will play a copy-protected CD that does not conform
to standards.

In the following cases, check and adjust the system clock before operation.
 After transportation
 After storage
 After the server is used following a period of disuse, in which storage conditions did not conform to
those that guarantee server operations (temperature: 5C to 40C (when the high-temperature
environment is set: 5 to 48°C (it's subject to composition restrictions.)); humidity: 10% to 85% (10% to
80% (when internal LTO is installed)).

Check the system clock approximately once per month.

We recommend you store the server at room temperature. Keep the following storage conditions.
Temperature: 10C to 55C, Humidity: 10% to 85% (10% to 80% (when internal LTO is installed), No
condensation of moisture)

Do not power off or reset the server, nor disconnect the power cord before POST completes.

If this server, internal optional devices, and media set for the backup devices (tape cartridges) are moved
from a cold place to a warm place in a short time, condensation will occur and cause malfunctions and failures
when these are used in such state. To protect important stored data and property, make sure to wait for a
sufficient period to use the server and components in the operating environment.
Reference: Time effective at avoiding condensation in winter (more than 5C or more differences between
the room temperature and atmospheric temperature)
Disk devices: Approximately 2 to 3 hours

For optional devices, we recommend you use our NEC products. Even if they are successfully installed or
connected, installation of unsupported devices can cause the server to malfunction or even failure. You will
be charged to repair failure or damage caused by use of such products even within warranty period.
