Handling precautions
(
for proper operations
)
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. Ideal Location and Connection).
Before connecting/removing cables to/from peripheral devices, make sure that the server is off and
unplug the power cord.
Connect the provided power cord to a 100 VAC outlet. If an optional cable is used, you may connect
to a 100 or 200 VAC power system.
Make sure that the access LED on the server is off before turning off the power or ejecting an optical
disk.
After connecting power cord to power outlet, do not press the POWER switch to turn on the server
before the POWER LED (amber) is unlit.
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.
Wait for at least 30 seconds before connecting power cord after disconnecting it from power outlet.
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
C 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.
If you notice that the system clock runs significantly faster or slower over time even after adjustment,
contact the store where you purchased the product or your maintenance service company for repair.
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.
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 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.
