Handling precautions

(

for proper operations

)

Be sure to observe the following precautions for the proper functioning of the server. Ignoring the precautions

may cause server malfunction or failure.

• Do not use any cell phone or PHS and switch off them near the server. Electric waves from such

devices can cause server to malfunction.

• Install the server in an appropriate place. For details about the installation location, 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, if they are non plug-and-play devices.

• 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 connecting power cord to power outlet after disconnecting it.

• 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.

• Do not press the POWER switch to turn on the server before the POWER LED (amber) is unlit.

• Wait for at least 30 seconds before turning on the server after turning off the server.

• 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

server’s optical disk drive.

• 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: see the table below; humidity: 20% to 80%).

• 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.

• Observe the storage conditions (Temperature: −10°C to 55°C, Humidity: 20% to 80%, No

condensation of moisture) to store the server.

• Do not power off or reset the server, nor disconnect the power cord before POST completes.

• 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. Even if they are successfully

installed or connected, installation of unsupported devices can cause the server to malfunction or

even failure. You will be charged to repair failure or damage caused by use of such products even

within warranty period.
