Notes on Using Your Server 1-13
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 disc.
„
When you have just turned off the server, wait at least 10 seconds before turning it back
on. If the server is connected to the UPS, set at least 10 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 9 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 standard, the playback of such a disc with the
optical disk drive is not guaranteed.
„
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 internal devices and the unit to operate correctly in
the next operation.
„
It is recommended that the server, the internal devices, and media (such as tape cartridge)
should be stored in a place where the room temperature can be maintained. It is important
for the server or internal devices to work normally after storage. Store the device in the
place where temperature ranges between -10 to 55°C and humidity ranges between 20 to
80%, without dew condensation.
