Chapter 1 Maintenance
1.
Transfer, Movement, and Disposal
1.1
Transfer to a Third Party
Observe the following precautions when you transfer (or sell) the server or software provided with the server
to a third party.
•Server
When transferring (or selling) the server to a third party, be sure to provide the server’s instructions
(including electronic manuals) to the third party.
•Data on hard disk drives
Be sure to erase the data stored in hard disk drives to prevent the leakage of sensitive data (such as
customer information or company management information) to any third parties. It is the user’s responsibility
to erase the data.
Important NEC assumes no liability for data leakage should the product be transferred
to a third party without erasing the data.
Data seems to be erased when you empty "Recycle Bin" of Windows or execute the "format" command of
the operating system. However, the actual data remains on the hard disk drive. Data not erased completely
might be restored by special software and used for unexpected purposes.
•Bundled software
Observe the following precautions when transferring (selling) the bundled software to a third party.
−Transfer them with the server.
−All provided media and documents must be transferred and no backup copies must be retained.
−Transfer requirements listed in "Software License Agreement" that comes with each software application
must be satisfied.
−Software on client PC must be uninstalled before transferring.

1. Transfer, Movement, and Disposal
Scalable Modular Server DX2000 Maintenance Guide 13
Chapter 1 Maintenance
1.2
Disposal of the Server and Consumables
•Dispose of this server, hard disk drives, option boards, and batteries according to laws and regulations of
the central and/or local government. Also dispose of the power cord attached to this product together with
the server to prevent diversion to other products.
Note •For disposal (or replacement) of the battery in the server module and CSC
module, consult with your sales representative.
•It is the user’s responsibility to completely erase all data stored on storage
devices such as hard disk drives, backup data cartridges, or any other media
(such as CD-R/CD-RW) so that the data cannot be restored by a third party.
•Some components including fans and solid state drives (SSD) work for a limited period of time and require
replacement. For stable operation of the server, NEC recommends you regularly replace these
components. Contact your sales representative for information on replacement or the lifetime of
components. The replacement service of SSDs that reached their end of life will be charged.
1.3
Regarding the Transportation of This Server
This server and/or some of the associated optional devices uses lithium metal batteries. Regulations for
air/ocean transportation apply when transporting lithium batteries. Conform to the regulations if you
want to transport this server or optional devices by air or ship.
1.4
Moving and Storing
Follow the steps below when you move or store this server.
WARNING
Be sure to observe the following precautions to use the server safety. Failure to
observe the precautions may cause death or serious injury. For details, refer to

Chapter 1 Maintenance
CAUTION
Be sure to observe the following precautions to use the server safely. Failure to
observe the precautions may cause burns, injury, and property damage. For
details, refer to Safety precautions in Precautions for Use in User’s Guide.
•Make sure to complete installation.
•Do not get your fingers caught.
•Be careful of handling internal components that may be at high temperatures.
Note •If the server needs to be relocated or stored due to a change in the floor
layout to a great extent, contact your sales representative.
•If the server has hard disk drives, move the server while being careful not to
damage the drive.
•When storing the server, monitor the environmental conditions of the storage
area (temperature: −10°C to 55°C, humidity: 20% to 80%). (No dew
condensation is permitted)
Tips Make backup copies of important data stored in the hard disk drives.
1. Shut down all the server modules installed in this server.
2. Unplug the power cord of the server from the power outlet.
3. Confirm that the POWER LED is off.
4. Disconnect all the cables from the server.
Pull out the server from the rack slowly, withthree or more people. For the procedure, refer to Chapter 2,
Installation and Connection in DX2000 User’s Guide.
5. Pack the server securely to protect from damage, shock, and vibration.
Important If this server is suddenly moved from a cold place to a warm place,
condensation will occur and cause malfunctions and failures when the
server is used in such a state. Wait for a sufficient period of time before
using the server in the operating environment.
Note •Check and adjust the system clock before operating after relocating or storing
the server.
•If the system clock time is significantly delayed or advanced over time in spite of
adjustment, contact your sales representative.

2. Daily Maintenance
Scalable Modular Server DX2000 Maintenance Guide 15
Chapter 1 Maintenance
2.
Daily Maintenance
To use the server under good conditions at all times, periodically check and perform maintenance as follows. If
abnormalities are found, ask your sales representative, avoiding impossible operation.
2.1
Monitoring CSC modules
We strongly recommend that you monitor CSC modules remotely during normal system operation.
If not, CSC module’s faults might not be detected.
The user needs to prepare a monitoring program.
To monitor CMM from a management terminal, use an IPMI command such as sensor list.
2.2
Alerting from BMC and CSC modules
When running the system, we strongly recommend that you use PET alert features to monitor your system.
The BMC and CSC modules can send a PET alert when abnormality such as a hardware error occurs. For
how to configure alert features, refer to Chapter 1 (7.3.1 SNMP trap setting command). For a list of alerts,
refer to Chapter 1 (4. Troubleshooting).
Platform event trap (PET) events are SNMP trap events compliant with the Intelligent Platform Management
Interface (IPMI). The user needs to prepare a program for receiving traps.
2.3
Checking STATUS LED
Check the STATUS LED on the front of the server. For the functions and descriptions of the LED, refer to
Chapter 1 (3. Names and Functions of Parts) in DX2000 User’s Guide. If the indicator shows the server
abnormality, contact your sales representative.
2.4
Backup
We recommend that you periodically back up the data on the hard disk drives, as well as NW switch settings.
For a storage device for back up and a backup tool suitable for your system, contact your sales
representative.
Refer to NEC Scalable Modular Server DX2000 LAN Switch Software Configuration Guide for more
information about backing up NW switch settings.

4.1 From Power On to When the NW Switch Module Starts
Operating
[?] Fail to power on the server
Is the server properly supplied with power?
Check that the AC POWER LED on the rear of the server lights green.
Check if the power cord is connected to the power outlet that meets the power specifications for the
server.
Use the power cord that comes with the server. Additionally, check the power cord for broken shield or
bent plugs.
