FOR PROPER OPERATION
Observe the following notes for successful operation of the server. Use of the server ignoring the
notes will cause malfunctions or failures of the server.
CPU blade
– N8400-110F/114F CPU blade assembly can 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.
– The CPU blade is extremely sensitive to static electricity. Make sure to touch the metal
frame of the server to discharge static electricity from your body before handling the
CPU blade. Do not touch the CPU blade terminals or on-board parts by a bare hand and
place the CPU blade directly on the desk.
– Check and adjust the system clock before the operation if any of the following
conditions is applicable.
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 service representative to ask maintenance.
– Store the unit under the storage condition (temperature: -10°C - 55°C, humidity: 20% -
80%, without condensation) to allow built-in devices and the unit to operate correctly
in the next operation.
– Before turning off the power of a CPU blade, shut down the CPU blade correctly.
– Turn on the power of each CPU blade by the use of the POWER switch or the remote
power-on after the period of 30 seconds or longer has passed from the supply of AC
power (the POWER lamp of the CPU blade goes on amber) to every power unit. The
power of the CPU blade may not be turned on if the power-on operation is done within
the period of less than 30 seconds from the supply of AC power. After making sure that
the AC power is supplied to every power unit, turn on the power of each CPU blade by
using the POWER switch.
– After turning off the power of a CPU blade once, turn on the power again after 30
seconds have passed from the power-off.
– Remove a CPU blade after turning off the power of the CPU blade.
After carriage of device
After storage of device
After the device is entered into the pause state under the environmental
condition enduring device operation (temperature: 10°C - 35°C, humidity:
20% - 80%)
