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.
Installation site
Install the server in an appropriate place. See
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 supply
Connect the provided power cord to a 100 VAC outlet.
Connect the dedicated power cord to a 200 VAC outlet.
Uninterruptible Power Supply (UPS) is used for preventing the momentary voltage drop. The server does not
support UPS connection through the serial port (RS-232C) and power control by PowerChute Plus.

Wait for at least 30 seconds before turning on the server after connecting the power cord to the outlet.
If UPS is connected, set the schedule to wait for at least 30 seconds before turning on the server.
Do not press POWER Switch to turn on the server while POWER LED lights amber.
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.
