1-8 Notes on Using Your Server
FOR PROPER OPERATION
Observe the following notes for successful operation of the server. Use of the server ignoring the
notes will cause malfunctions or failures of the server.
„
Install the server in a place that meets requirements for successful operation. For details,
see Chapter 3, "Setting Up Your Server."
„
Make sure to power off the server before connecting or disconnecting cables between the
server and peripheral devices.
„
When you have just turned off the server, wait at least 10 seconds before turning it on
again. If the server is connected to the UPS, set at least 10 seconds delay in the power-on
schedule.
„
For the disk which does not conform to the CD standard, the playback of such a disk with
the optical disk drive is not guaranteed.
„
Turn off the power and unplug the power cord from the outlet before relocating the server.
„
Clean the server on a regular basis. (See Chapter 7 for cleaning.) Regular cleaning
proactively prevents various failures of the server.
„
Lightning may cause a momentary voltage drop. To prevent this problem, it is
recommended to use an uninterruptible power supply unit.
„
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.
„
Check and adjust the system clock before the operation in any of the following conditions:
– After carriage of device
– After storage of device
– After the pause state of the device placed in the environment beyond the specified
range of condition for adequate operation (temperature: 10°C - 35°C, humidity: 20% -
80%)
„
Check the system clock about 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 remarkably delays or gains in spite of the adjustment, contact your
service representative for maintenance.
„
Store the unit under the adequate storage condition (temperature: –10°C - 55°C, humidity:
20% - 80%, without condensation) to allow built-in devices and the unit to work correctly
in the next operation.
„
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 the use of such third-party products will be charged.
„
Turn off the cellular phone or pager. Radio interference may cause malfunctions of the
server.
