Security Note
Using a network controllable product with its default password may raise a serious risk as it may be hacked by
some malicious third person. If a product is supplanted by a malware, it will face possibilities of not only
information leakages, but also system damages obstructing its availability and/or integrity. Even if it does not
cause damage to own system, the product may be used as a botnet to make a cyber-attack to some other
systems.
The default password on our product is provided only for the purpose of changing initial setting during its installation
service. In first change of initial setting, please be sure to change the password. NEC Platforms, Ltd. shall not take
any liability and responsibility for any damages arising from illegal access.
If the new password is not strong (too short) or easily guessed (such as "123456789", "abcdefg", "password",
"Administrator"), illegal access cannot be prevented. Please be sure to use a strong password (use 8 digits or
longer, and including numerals, capital letters and small letters).
<<How to change your password>>
Refer to P11 2.8 Changing Password section.

1. Introduction
1.1 NW Switch Module Diagram
Two NW Switch modules are installed in a chassis. Each NW Switch module consists of external interfaces
(40Gbps QSFP+ x8ports) and internal interfaces (for each CPU Slot 10Gbps x1).
The figure below shows the NW Switch Module Diagram.
The number 1 to 79, “mgmt” and “internal” show the physical ports. For more details, please refer to the next page.
Note:
Each NW Switch modules works individually. These NW Switch modules are not stackable.
The NW Switch module doesn’t support Direct Attach Cable.

2. System Configuration
DX2000 NW Switch Configuration Guide 9
2. System Configuration
2.1 Saving a system configuration
You can save the current configuration using the following command.
Switch>enable
Switch#write
Building configuration...
[OK]
Reboot or shutdown the NW Switch Module without saving will discard the changes.
2.2 Restore initial configuration
To restore the default configuration, use the following commands.
Switch>enable
Switch#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Switch(config)#system restore default-config
This task requires reboot system,
do you want to continue? (y/n):y
Note: This command will automatically reboot the NW Switch Module.
2.3 Exporting Switch Configuration
You can export saved configuration from the NW Switch Module to an external server by TFTP using the following
commands.
(Save the configuration (execute “write”) before exporting the configuration.)
Example:
To export configuration file named “startup-config” to TFTP server (IP address 192.168.7.254),
Switch>enable
Switch#copy startup-config tftp
Enter IP:192.168.7.254
Enter port [69]:69
Enter filename:startup-config
* User can also use the command below
copy startup-config tftp tftp://192.168.7.254/startup-config
2. System Configuration
DX2000 NW Switch Configuration Guide 10
2.4 Importing Switch Configuration

Enter IP:192.168.7.254
Enter port [69]:69
Enter filename: startup-config
Copy Success...
You need to reboot the NW Switch Module (“reload” command) to enable the new configuration.
* User can also use the command below
