Handling precautions
(
for proper operations
)
Observe the following notes for successful operation of the workstation. Use of the workstation ignoring the notes
will cause malfunctions or failures of the workstation.
•
To connect the workstation to the power receptacle that accepts 200 VAC, use the separately priced power
cord for 200 VAC.
•
Verify that the access LED on the workstation is unlit before turning off the workstation.
•
When you have just turned off the workstation, wait at least 10 seconds before turning it back on. If the
workstation is connected to UPS, set 10-second delay in time schedule.
•
Powering off the workstation by pressing the POWER/SLEEP switch for several seconds on the screen other
than OS (POST, BIOS SETUP, or Windows) may restart the workstation.
•
Momentary voltage drop may occur due to lightning strike. To prevent this, use of UPS is recommended.
•
If you installed the optional graphics accelerator board, install the display driver according to the manual
provided with the graphics accelerator board.
•
If you specify 9KB for Jumbo Frame size in LAN configuration, expected performance may not be obtained
due to running condition or network environment. In this case, specify 4KB for Jumbo Frame size.
•
If this workstation, internal optional devices, and media set for the backup devices (tape cartridges) are
moved from a cold place to a warm place in a short time, condensation will occur and cause malfunctions and
failures when these are used in such state. To protect important stored data and property, make sure to wait
for a sufficient period to use the workstation and components in the operating environment.
Reference: Time effective at avoiding condensation in winter (more than 10
°
C differences between the
room temperature and atmospheric temperature)
Hard disk drive: Approximately 2 to 3 hours
Tape media: Approximately 1 day
•
For optional devices, we recommend you use our NEC genuine products. Even if they are successfully
installed or connected, installation of unsupported devices can cause the workstation to malfunction or even
failure. You will be charged to repair failure or damage caused by use of such products even within warranty
period.
•
Be sure to turn off the cell phone or PHS near the workstation. Electric waves from such devices can cause
workstation to malfunction.
•
When you have just removed the USB device, wait at least 5 seconds before inserting it.
