1-12 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.
Make sure to power off the server before connecting or disconnecting cables between the
server and peripheral devices.
Verify that the access LED on the server is unlit before turning off the server or ejecting
the floppy disk.
When you have just turned off the server, wait at least 30 seconds before turning it back
on.
If the server is connected to the UPS, set at least 30 seconds delay in the power-on
schedule.
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 of an uninterruptible power supply unit.
For the disc which does not conform to the CD standard, the playback of such a disk with
the DVD/CD drive is not guaranteed.
If an additional LAN card is installed in PCI slot, it is hard to push the catch of the
connector with your finger that is connected to the LAN port. Disconnect the connector
pushing the catch with a standard screwdriver. At this time, be very careful for the
screwdriver not to damage the LAN port or other ports.
Check and adjust the system clock before the operation if any of the following conditions
is applicable.
– After carriage of device
– After storage of device
– After the device is entered into the pause state under the environmental condition
enduring device operation (temperature: 10°C - 35°C, humidity: 20% - 80%)
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 built-in devices and the unit to operate 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 use of such third-party products will be charged.
Turn off the cellular phone or pager. Radio interference may cause malfunctions of the
server.
