Handling precautions
(
for proper operations
)
Be sure to observe the following precautions for the proper functioning of the server. Ignoring the
precautions
may cause server malfunction or failure.
Installation site
Install the server in an appropriate place. Refer to
Chapter 2 Preparations (2. Installation and
Connection)
.
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.
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.)
When you store the server for a long time period, keep it under storage environment conditions
(Temperature: –10 to 55°C, Humidity: 20 to 80%, non-condensing).
Turn off the server and unplug the power cord before moving it.
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 to 35°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.
Power suply
Connect the provided power cord to a 100 VAC outlet.
Connect the dedicated power cord to a 200 VAC outlet.
Momentary voltage drop may occur due to lightning strike. To prevent this, use of UPS is
recommended.
The server does not support UPS connection via serial port (RS-232C) and power control by
PowerChute Plus.
Power-on/Power-off
Wait for at least 30 seconds before turning on the server after connecting the power cord to the
outlet.
If a Uninterruptible Power Supply unit is connected, set it to wait for at least 30 seconds before
turning on the server.
Do not press the POWER switch to turn on the server before the POWER LED (amber) is unlit.
Do not power off or reset the server, nor disconnect the power cord before POST completes.
Make sure that the access LED 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.
When disconnecting power cord from outlet, wait at least 30 seconds before connecting the power
cord.
For stable operation, it is recommended to restart OS after the system has been duplexed.
