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.
●
General
–
Do not block air vents of the CPU blades, Blade Enclosures, power supply units, and additional fan units.
–
The CPU blade and internal option devices contain precision component that is easily affected by drastic
temperature change. If the device is used after storage or relocation, make sure that the device is fully
adapted to the operating environment.
–
Do not touch the CPU blade terminals or on-board components by a bare hand nor place the CPU blade
directly on the desk.
–
It is recommended to use options provided by NEC. Some memory devices and solid state drives of
other vendors are designed to be available for the server. If such an option causes the server to be
defected or damaged, you will be charged for the repair within the warranty period.
–
Turn off the cellular phone or pager around the server. Radio interference may cause malfunctions of the
server.
●
CPU blade
–
N8400-230F/231F/232F/233F/234F/236F CPU blade should be installed in the Blade Enclosure
(SIGMABLADE).
–
Install or remove CPU blades one by one.
–
Hold the portions covered with metal plates when a CPU blade is installed or removed. To carry a CPU
blade, put it into the case in which the CPU blade was contained at the purchase and pack it into the
package.
–
Check and adjust the system clock before the operation if any of the following conditions is applicable.
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 at the rough rate of once per month. When the system clock is installed in a
system requiring high time precision, it is recommended to use a time server (NTP server).
If the system clock is remarkably delayed or advanced as the passage of time in spite of adjustment,
contact your sales representative to ask maintenance.
–
Store the unit under the storage condition (temperature: –10°C to 55°C, humidity: 20% to 80%, without
condensation).
–
Turn on the power of each CPU blade by pressing the POWER switch or the remote power-on operation
after the period of 60 seconds or longer has passed from the supply of power (the POWER LED of the
CPU blade goes on amber). The power of the CPU blade may not be turned on if the power-on operation
is done within the period of less than 60 seconds from the supply of power. After making sure that the
power is supplied to every CPU blade, turn on the power of each CPU blade by pressing the POWER
switch.
