Handling Precautions - NEC Express5800 Series 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 not plug-and-play device, make sure that the server is off and unplug the power
cord before connecting/removing cables to/from the device.

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.

Turn off the server and unplug the power cord before moving it.

Regularly clean the server to prevent various types of failure. For details, see Chapter 1 (2. Daily
Maintenance) in "Maintenance Guide".

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 the storage conditions did not conform to
the conditions that guarantee server operations (temperature: 5 to 40°C (when High Temperature
Resistant Kit is installed: 5 to 48°C (it's subject to composition restrictions.)); humidity: 10% to 85%).

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% (No condensation of moisture)

Do not use the server, or removable/backup media such as tape cartridges when moving them from a cold
place to a warm place. The condensation will occur and cause malfunctions and failures when these are
used in such state. Use the server after waiting sufficiently.
Reference: Time effective at avoiding condensation in winter (5C or more differences between the room
temperature and atmospheric temperature)
 Disk devices: Approximately 2 to 3 hours
 Tape media: Approximately 1 day

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.
