Safety Notices
!

Caution: To reduce the risk of electric shock which could cause personal
injury, follow all safety notices. The symbols shown are used in your
documentation and on your equipment to indicate safety hazards.

Warning: Lithium batteries can be dangerous. Improper handling of lithium
batteries may result in an explosion. Dispose of lithium batteries as required
by local ordinance or as normal waste if no local ordinance exists.

Warning: The detachable power supply cord is intended to serve as the
disconnect device.

Warning: This equipment has a 3-wire, grounded power cord. To prevent
electrical hazards, do not remove or defeat the ground prong on the power
cord. Replace the power cord if it gets damaged. Contact your dealer for an
exact replacement.

Warning: The DC push-button on/off switch on the front panel does not turn
off the system AC power. Also, +5vdc is present on the system board
whenever the AC power cord is connected between the system and an AC
outlet. Before doing the procedures in this manual, make sure that your
system is powered off and unplug the AC power cord from the back of the
chassis. Failure to disconnect power before opening your system can result in
personal injury and equipment damage.
In the U.S.A. and Canada, the power cord must be a UL-listed detachable power
cord (in Canada, CSA-certified), type ST or SJT, 16 AWG, 3-conductor,
provided with a molded-on NEMA type 5-15 P plug cap at one end and a
molded-on cord connector body at the other end. The cord length must not
exceed 9 feet (2.7 meters).
Outside the U.S.A. and Canada, the plug must be rated for 250 VAC, 10 amp
minimum, and must display an international agency approval marking. The cord
must be suitable for use in the end-user country. Consult your dealer or the local
electrical authorities if you are unsure of the type of power cord to use in your
country. The voltage change occurs via a switch in the power supply.

Warning: Under no circumstances should the user attempt to disassemble the
power supply. The power supply has no user-replaceable parts. Inside the
power supply are hazardous voltages that can cause serious personal injury. A
defective power supply must be returned to your dealer.
Safety Notices for Users Outside of the U.S.A. and Canada

Preface - vii

PELV (Protected Extra-Low Voltage) Integrity: To ensure the extra-low
voltage integrity of the equipment, connect only equipment with mains-
protected electrically-compatible circuits to the external ports.

Remote Earths: To prevent electrical shock, connect all local (individual
office) computers and computer support equipment to the same electrical
circuit of the building wiring. If you are unsure, check the building wiring to
avoid remote earth conditions.

Earth Bonding: For safe operation, only connect the equipment to a building
supply that is in accordance with current wiring regulations in your country.
In the U.K., those regulations are the IEE.

Preface - viii

STATUS INDICATORS
This section explains the indication and meanings of the server lamps.
ACT Lamp ( )
The ACT lamp is green while the server is connected to the LAN. The lamp flashes while the
server is accessed via the LAN (during transmission/reception of packets). The number next to
the icon indicates the network port number on the rear panel of the server.
POWER Lamp ( )
The green POWER lamp lights to indicate normal operation while the server is powered.
When the server is off-powered, the POWER lamp stays unlit.
The POWER lamp indicates that the server is running in the power-saving mode (sleep mode).
If the OS supports the power-saving mode such as Windows 2000, running a command blinks
the POWER lamp in green and place the server in the power-saving mode. Press the POWER
switch to turn out the POWER lamp and place the server back in the normal mode.
The power-saving mode is only available when the OS supports the power-saving feature.
Some OS's allow you to set the server to automatically turn in the power-saving mode when no
access is made to the server for a certain period of time or to select the power-saving mode with
a command.
STATUS Lamp ( )
The STATUS lamp is on (green) while the server is operating normally. (The rear panel also
has the STATUS lamp on it.) If the STATUS lamp is off or turns amber and flashes, it indicates
that the server is in abnormal state.
The table below explains the STATUS lamp indication, the meanings, and the procedures.
NOTES:
 If NEC ESMPRO or the offline maintenance utility is installed, you
can confirm the cause of a failure by referring to the error log.
 If shutdown processing can be performed through the operating
system when you want to restart the system after turning the power
off, restart the system by performing shutdown processing. If
shutdown processing cannot be performed, restart the system by
resetting, forcibly turning the power off, or disconnecting and then
connecting the power cord.

10 System Overview
