Regulatory and Safety Notices

•
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 connecting power cord to power outlet after disconnecting it.
•
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.
•

•
Wait for at least 30 seconds before turning on the server after turning off the server.
•
Turn off the server and unplug the power cord before moving it.
•
Regularly clean the server to prevent various types of failure. For details about cleaning, refer to
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 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.
•
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.
•
Observe the following storage conditions to store the server.
Temperature: −10°C to 55°C, Humidity: 20% to 80%, 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 10°C 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 third party's devices
are successfully installed or connected, installation of unsupported devices can cause the server
