For Proper Operation - NEC NovaScale R480 E1 User Manual

FOR PROPER OPERATION

Observe the following notes for successful operation of the server. Using the server while ignoring the notes will cause
malfunctions or failures of the server.
Install the server in a place that meets the requirements for successful operation. For more information, 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.
Make sure that the access LED on the server is unlit before turning off the server or ejecting the floppy disk.
The server management logic on your system board monitors and logs system voltage changes. When
plugging the power cord to the system, you may experience a 10 seconds delay between power on and the
time you pressed the POWER/SLEEP switch on the front panel. This is normal system operation and is
required by the server management logic.
If you power off the server, wait at least 30 seconds before powering it back on.
Do not power off the server until characters following the full screen logo have appeared on the screen. It may
take one to five minutes depending on your configuration.
Power off the power and unplug the power cord from the outlet before relocating the server.
Some software include a command allowing you to eject the CD-RW/DVD-ROM drive tray. Make sure that
the front bezel is removed before running the command. Running this command with the front bezel installed
may cause the CD-RW/DVD-ROM drive tray or the media to hit the front bezel, resulting in a failure of the
server
Clean the server on a regular basis. (See Chapter 7 for cleaning.) Regular cleaning proactively can prevent
various failures of the server.
Lightning may cause a momentary voltage drop. To prevent this problem, we recommend you use an
uninterruptible power supply unit.
Check and adjust the system clock before the operation if any of the following conditions is applicable.
– After carrying of the server
– After storage of the server
– After the server entered into the pause state under the following environmental conditions (temperature:
10°C - 35°C, humidity: 20% - 80%)
Check the system clock roughly once per month. If the system clock is installed in a system requiring high
time precision, we recommended you use a time server (NTP server).
If the system clock is delayed or advanced as time goes by in spite of adjustment, contact your sales agent and
request a maintenance operation.
Store the unit under the approved storage conditions (temperature: -10°C - 55°C, humidity: 20% - 80%,
without condensation) to allow the built-in devices and the unit to operate correctly in the next operation.
Make sure to use the 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.
We recommend you use our genuine products. Some third-party products claim that they support our server.
However, repairing the server due to a failure or damage resulting from the use of such third-party products
will be charged.
Playback of disks which do not conform to the CD or DVD standard is not guaranteed.
Power off any cellular phone or pager. Radio interferences may cause malfunctions of the server.
