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.
 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.
 Playback of disks which do not conform to the CD or DVD standard is not guaranteed.
 Power 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 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.
 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.
 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.
 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.
 Power off any cellular phone or pager. Radio interferences may cause malfunctions of the server.
