1-12 Precautions for Use
For Proper Operation
Observe the following instructions for successful operation of the server. Failure to observe them
could lead to malfunction or breakdown.
Perform installation in a place where the system can operate correctly. For details, see the
separate volume “User’s Guide (Setup).”
Before turning off the power or ejecting a disk, make sure that the access LED is off.
When you have just turned off the power, wait at least 30 seconds before turning it on again.
Once you have turned on the server, do not turn it off until the "NEC" logo appears on the
screen.
Plug the attached cord in the outlet whose AC input voltage is 100V.
After plugging in the power cord, do not turn on the power of the equipment for 30 seconds.
Before you move the equipment, turn off the power and unplug the cord.
This server shall not assure reproduction of copy-protect CDs using reproduction equipment
if such disks do not comply with CD standards.
Clean the equipment regularly. (For procedures, see Chapter 6.) Regular cleaning is effective
in preventing various types of trouble.
Lightning may cause voltage sag. As a preventive measure, it is recommended to use UPS
(uninterruptible power supply).
This equipment does not support the connection through an UPS serial port (RS-232C) or the
control using PowerChutePlus.
Check and adjust the system clock before operation in the following conditions:
- After transporting the equipment
- After storing the equipment
- After the equipment halt under the conditions which is out of the guranteed
environment conditions (Temperature: 10 to 35
°C, Humidity: 20 to 80%).
Check the system clock once in a month. It is recommended to operate the system clock
using a time server (NTP server) if it is installed on the system which requires high level of
time accuracy. If the system clock goes out of alignment remarkably as time goes by, though
the system clock adjustment is performed, contact your sales agent.
When you store the equipment, keep it under storage environment conditions (Temperature:
-10 to 55°C, Humidity: 20 to 80%, non-condensing).
If NEC Express5800/ft series, the built-in optional devices, and the 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 breakdown when these are used in such
state. In order to protect important stored data and assets, make sure to wait for a sufficient
period of time to use the server or components in the operating environment.
Reference: Length of the time effective at avoiding condensation in winter (more than 10°C
differences between room temperature and atmospheric temperature)
Disk devices: Approximately 2-3 hours
Tape media: Approximately 1 day
