CAUTION
Do not attempt to install the server yourself.
To avoid a risk of injuries, users should not attempt to install the equipment into
a rack. Installation should be performed by trained maintenance personnel.
< For Maintenance Personnel Only >
Do not remove and carry the equipment with modules mounted.
When you remove this product from the rack and carry it, remove all modules
that are mounted first.
Do not install the equipment in such a manner that its weight is imposed on a
single place.
To distribute the weight, attach stabilizers or install two or more racks. It may
fall down to cause injuries.
Do not assemble parts alone.
It takes at least two people to mount doors and trays to a rack. You may drop
some parts to cause a breakage or injuries.
Do not pull a device out of the rack if it is unstable.
Before pulling out a device, make sure that the rack is fixed (by stabilizers or
quake-resistant engineering).
Do not leave two or more devices pulled out from the rack.
If you pull out two or more devices the rack may fall down. You can only pull out
one device at a time.
Do not install excessive wiring.
To prevent burns, fires, and damage to the equipment, make sure that the rated
load of the power branch circuit is not exceeded. For more information on
installation and wiring of power-related facilities, contact your electrician or local
power company.

For Proper Operation
Observe the following instructions for successful operation of the server. Failure to observe them
could lead to malfunction or breakdown.
Perform installation in a place where the system can operate correctly. For details, see the
separate volume “User’s Guide (Setup)”.
Before turning off the power or ejecting a disk, make sure that the access LED is off.
When you have just turned off the power, wait at least 30 seconds before turning it on again.
Once you have turned on the server, do not turn it off until the "NEC" logo appears on the
screen.
Before you move the equipment, turn off the power and unplug the cord.
This server shall not assure reproduction of copy-protect CDs using reproduction equipment
if such disks do not comply with CD standards.
Clean the equipment regularly. (For procedures, see Chapter 6.) Regular cleaning is effective
in preventing various types of trouble.
Lightning may cause voltage sag. As a preventive measure, it is recommended to use UPS
(uninterruptible power supply).
This equipment does not support the connection through an UPS serial port (RS-232C) or the
control using PowerChutePlus.
Check and adjust the system clock before operation in the following conditions:
- After transporting the equipment
- After storing the equipment
- After the equipment halt under the conditions which is out of the guranteed
environment conditions (Temperature: 10 to 35
°C, Humidity: 20 to 80%).
Check the system clock once in a month. It is recommended to operate the system clock using
a time server (NTP server) if it is installed on the system which requires high level of time
accuracy. If the system clock goes out of alignment remarkably as time goes by, though the
system clock adjustment is performed, contact your sales agent.
When you store the equipment, keep it under storage environment conditions (Temperature:
-10 to 55°C, Humidity: 20 to 80%, non-condensing).
If NEC Express5800/ft series, the built-in optional devices, and the media set for the backup
devices (tape cartridges) are moved from a cold place to a warm place in a short time,
condensation will occur and cause malfunctions and breakdown when these are used in such
state. In order to protect important stored data and assets, make sure to wait for a sufficient
period of time to use the server or components in the operating environment.
Reference: Length of the time effective at avoiding condensation in winter (more than 10°C
differences between room temperature and atmospheric temperature)
Disk devices: Approximately 2-3 hours
Tape media: Approximately 1 day
Make sure that the optional devices are attachable and connectable to the equipment. There
is a risk of malfunctions that could lead to a breakdown of the equipment even if you could
attach and connect.
