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 cellphones 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 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 not plug-and-play devices.
•
Connect the provided power cord to a 100/200 VAC outlet.
•
Do not press the POWER switch until the UID LED (lighting in blue) goes out after connecting the
power cord of this machine to an outlet or mounting the server module.
•
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.
•
Wait for at least 20 seconds before inserting a server module after removing it.
•
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.
•
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, see Chapter 1 Maintenance
(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 support 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
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
This server does not support hibernation and standby mode.
•
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.
