Handling Precautions (For Proper Operations) - NEC Express5800/GT110e EXP280A User Manual

Handling precautions
Be sure to observe the following precautions for the proper functioning of the server. Ignoring the precautions
may cause server malfunction or failure.
• Do not use any cell phone or PHS and switch off them near the server. Electric waves from such
devices can cause server to malfunction.
• Install the server in an appropriate place. For details about the installation location, refer to Chapter 2
Preparations (2. Installation and Connection).
• Before connecting/removing cables to/from peripheral devices, make sure that the server is off and
unplug the power cord, if they are non plug-and-play devices.
• Connect the provided power cord to a 100 VAC outlet. If an optional cable is used, you may connect
to a 100 or 200 VAC power system.
• Make sure that the access LED on the server is off before turning off the power or ejecting an optical
disk.
• Wait for at least 30 seconds before turning on the server after turning off the server. If any
Uninterruptible Power Supply unit is connected, set it to wait for at least 30 seconds before turning
on the server after power off.
• Turn off the server and unplug the power cord before moving it.
• Regularly clean the server to prevent various types of failure. (Refer to Chapter 1 Maintenance (2.
Daily Maintenance) in "Maintenance Guide" for details about cleaning.)
• Momentary voltage drop may occur due to lightning strike. To prevent this, use of UPS is
recommended.
• For some optional devices that can be installed in the optical disk drive or 5.25-inch device bay, it is
possible to eject the tray or media by executing a software command. Before you execute the
software command to eject, make sure that the front door is open. If you execute the command while
the front door is closed, the tray or media hits the door, which can cause not only errors but also
server failure.
• We do not guarantee that any copy-protected CD that does not conform to standards will play on the
CD player.
• Make sure that optional devices you are going to install are supported for use with the server. Even if
they are successfully installed or connected, installation of unsupported devices can cause the
server to malfunction or even failure.
• In the following cases, check and adjust the system clock before operation.
− After transportation
− After storage
− After the server is used following a period of disuse, in which storage conditions did not conform to those
that guarantee server operations (temperature: 10°C to 40°C; humidity: 20% to 80%).
• Check the system clock approximately once per month. Use of a time server (NTP server) is
recommended if high accuracy timing is required by the system.
