Handling Precautions (For Proper Operations) - NEC Express5800/R120d-2E User Manual

Handling precautions
Be sure to observe the following precautions for the proper functioning of the server. Ignoring the precautions
may cause server malfunction or failure.
•
To avoid the influence of the electric waves, switch of any cell phone or PHS near the server.
•
Place the server in an appropriate location. For details, refer to Chapter 2 Preparations (2.
Installation and Connection).
•
Before connecting/removing cables to/from peripheral devices, make sure that the server is off and
unplug the power cord.
•
Connect the provided power cord to a 100/200 VAC outlet.
•
Make sure that the access LED on the server is off before turning off the power or ejecting an optical
disk.
•
Wait for at least 30 seconds before turning on the server after turning off the server. If any
Uninterruptible Power Supply unit is connected, set it to wait for at least 30 seconds before turning
on the server after power off.
•
After connecting power cord to the server, do not press the POWER switch/LED before the POWER
LED (amber) is unlit.
•
Turn off the server and unplug the power cord before moving it.
•
Regularly clean the server to prevent various types of failure. (Refer to Chapter 1 Maintenance (2.
Daily Maintenance) in "Maintenance Guide" for details about cleaning.)
•
Momentary voltage drop may occur due to lightning strike. To prevent this, use of UPS is
recommended.
•
We do not guarantee that any copy-protected CD that does not conform to standards will play on the
CD player.
•
In the following cases, check and adjust the system clock before operation.
− 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
Check the system clock approximately once per month. Use of a time server (NTP server) is
recommended if high accuracy timing is required by the system.
*1: 10°C to 35°C when three N8103-153/162 RAID Battery Backup Units are installed.
• Observe the storage conditions (Temperature: −10°C to 55°C, Humidity: 20% to 80%, No
condensation of moisture) to store the server.
•
If this server, internal optional devices, and 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 failures when these are used in such state. To protect important stored data and
property, make sure to wait for a sufficient period to use the server and components in the operating
environment.
Reference: Time effective at avoiding condensation in winter (more than 10°C differences 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 our NEC products. Some memory or hard disk drives
manufactured by other companies are supported for use with this server, however, you will be
charged to repair failure or damage caused by use of such products even within warranty period.
