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)
.
Before connecting or removing the cable to or from a peripheral device that does not support the Plug and
Play function, make sure that the power to the server is off and remove the power cord from the outlet.
Switch off all cell phones in the proximity of the server. Electric waves from these devices can cause the
server to malfunction.
Regularly clean the server to prevent failure. See
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 operations (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.
The voltage may drop momentarily, for example, due to a lightning strike. To take measures against this, it
is recommended to use an uninterruptible power supply (UPS).
Power supply
Be sure to use this server within the rated current and voltage.
Power supply cord is not provided as a standard accessory with this server. Be sure to use power supply
cord specified by our company based on the power supply voltage and current depending on the
environment for use.
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.
Power-on/Power-off
Do not turn on the server after connecting the power cord to the outlet before the Module POWER LED on
the front of the device (see
Chapter 1 (4.8 LEDs)
) blinks in green (90 seconds).
If an uninterruptible power supply (UPS) is connected, set the schedule to wait for at least 90 seconds
before turning on the server.
Do not power off or reset the server, nor disconnect the power cord before POST completes.
Make sure that the DISK ACCESS LED or Optical DISK ACCESS LED is off before turning off the power or
ejecting media from a hard disk drive or an optical disk.
Allow 30 seconds or more to elapse when turning ON the power of the unit again after turning it to OFF.
When disconnecting power cord from the outlet, wait at least 30 seconds before connecting the power cord
again.
For stable operation, it is recommended to restart the OS after the system has been duplexed.
