Handling Precautions (For Proper Operations) - NEC express5800 A2010b 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 phone or PHS 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 about the installation location, refer to Chapter 2
Preparations (2. Installation and Connection).
•
Before connecting/removing cables to/from peripheral devices, make sure that the server is off and unplug
the power cord, if they are non plug-and-play 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 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. (Refer to Chapter 1 Maintenance (2. Daily
Maintenance) in "Maintenance Guide" for details about cleaning.)
•
Momentary voltage drop may occur due to lightning strike. To prevent this, use of UPS is recommended.
•
We do not guarantee that any copy-protected CD that does not conform to standards will play on the
server's optical disk drive.
•
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: 10 to 40°C; humidity: 20% to 80%).
•
Check the system clock approximately once per month. Use of a time server (NTP server) is recommended
if high accuracy timing is required by the system.
•
In order to get the server and internal devices to work properly, we recommend you store the server at
room temperature.
Observe the storage conditions (Temperature: −10°C to 55°C, Humidity: 20% to 80%, No condensation of
moisture) to store the server.
•
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 10°C 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.
