Power Supply - NEC Express5800 Serie Precauciones De Uso

• 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.

Power supply

• 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
• Wait for at least 30 seconds before turning on the server after connecting the power cord to the
outlet.
• If a UPS is connected, set the schedule to wait for at least 30 seconds before turning on the
server.
• Do not press POWER switch to turn on the server before the Module POWER LED on the front
blinks in green.
• Do not power off or reset the server, nor disconnect the power cord before POST completes.
• Make sure that the access LED is off before turning off the power or ejecting an optical disk.
• 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.
Optional devices
• We do not guarantee reproduction of copy-protected DVDs and CDs using reproduction
equipment if such disks do not comply with the relevant standards.
• If this server, internal optional devices, and media used as backup devices (tape cartridges) are
moved from a cold place to a warm place in a short period of time, condensation may occur,
causing malfunction or failure when these devices are next used. To protect important stored
data and assets, make sure to wait for a sufficient period before using the server and components
in the operating environment.
Reference: Time effective for avoiding condensation in winter (more than 10°C difference
between the room temperature and atmospheric temperature)
Disk devices: Approximately 2 to 3 hours, Tape media: Approximately 1 day
• For optional devices, we recommend you use NEC products. Even if they are successfully
installed or connected, installation of unsupported devices can cause the server to malfunction
or fail. You will be charged to repair failures or damage caused by the use of such products even
if it is within the warranty period.
