1.7 Handling precautions
Be sure to observe the following precautions to ensure that the server functions properly. Ignoring
these precautions may cause server malfunction or failure.
Installation site
• Install the server in an appropriate place. See Chapter 2 Preparations (2. Installation and
Connection) in User's Guide.
• Switch off all cell phones and PHS devices in the proximity of the server. Electric waves from
these devices can cause the server to malfunction.
• Regularly clean the server to prevent failure. Refer to Chapter 1 Maintenance (2. Daily
Maintenance) in Maintenance Guide for information about cleaning.
• When storing the server for a long time, be sure to satisfy the 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 the storage conditions did
not conform to the conditions that guarantee server operation (temperature 10 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 highly accurate timing is required by the system.
Power supply
• An uninterruptible power supply (UPS) is used to prevent momentary voltage drops. The server
does not support UPS connection through the serial port (RS-232C) or power control by
PowerChute Plus.
