1-14 Notes on Using Your Server
Check the system clock at the rough rate of once per month. When the system clock is
installed in a system requiring high time precision, it is recommended to use a time server
(NTP server).
If the system clock is remarkably delayed or advanced as the passage of time in spite of
adjustment, contact your service representative to ask maintenance.
Store the unit under the storage condition (temperature: –10°C - 55°C, humidity: 20% -
80%, without condensation) to allow internal devices and the unit to operate correctly in
the next operation.
If the server or an internal option device is brought from a cold place to a warm place
suddenly, the dew condensation may be generated resulting in malfunction or failure of
the unit. Leave the unit in the operating environment until it fully adapts to the
surroundings to protect the valuable data or property.
Guideline to eliminate dew condensation in winter time (10 degrees or more temperature
difference from the room temperature exists):
Disk drive: Two or three hours (approx.)
Make sure to use optional devices supported by the server. Some non-supported devices
may be physically installed/connected but cause failures of the server as well as
malfunctions of the server.
NEC recommends you use NEC's genuine products. Some third-party products claim that
they support the server. However, repair of the server due to a failure or damage resulted
from use of such third-party products will be charged.
Do not use a cellular phone or pager around the server. Turn off the cellular phone or
pager. Radio interference may cause malfunctions of the server.
