Use one of the following methods to define the TCP/IP settings for the Rack Monitor 250 for IPv4.

Device IP Configuration Wizard

The Device IP Configuration Wizard can discover the Rack Monitor 250 if it does not have an IP address assigned. Once discovered, you can configure its IP address settings.

System requirements

The Wizard runs on Microsoft Windows 2000, Windows Server® 2003, Windows Server 2012 and on both 32- and 64-bit versions of Windows XP, Windows Vista, Windows 2008, Windows 7, Windows 8 and Windows 10 operating systems.
This Wizard supports cards that have firmware version 3.0.x or higher and is for IPv4 only.

NOTE: Administrator access is required to run the Device IP Configuration Wizard.


To install the Wizard from a downloaded executable file:

  1. Go to
  2. Filter by Software Upgrades - Wizards and Configurators.
  3. Select and download the Network Management Device IP Configuration Wizard.
  4. Open the folder where you downloaded the Wizard, and run the executable file.

When installed, the Wizard is available through the Windows “Start Menu” option.

DHCP and BOOTP configuration

The default TCP/IP configuration setting, DHCP, assumes a properly configured DHCP server is available to provide TCP/IP settings to the Rack Monitor 250. You can also configure the setting for BOOTP.

A user configuration (.ini) file can function as a BOOTP or DHCP boot file. For more information, see the TCP/IP configuration section of the Rack Monitor 250 User Guide, available on the APC web site,

If neither of these servers is available, use the Device IP Configuration Wizard to configure the needed TCP/IP settings.


For the Rack Monitor 250 to use a BOOTP server to configure its TCP/IP settings, it must find a properly configured RFC951-compliant BOOTP server.

In the BOOTPTAB file of the BOOTP server, enter the MAC address of the Rack Monitor 250, IP address, subnet mask, and default gateway, and, optionally, a bootup file name. Look for the MAC address on the bottom of the Rack Monitor 250 or on the Quality Assurance slip included in the package.

When the Rack Monitor 250 reboots, the BOOTP server provides it with the TCP/IP settings.
• If you specified a bootup file name, the Rack Monitor 250 attempts to transfer that file from the BOOTP server using TFTP or FTP. The Rack Monitor 250 assumes all settings specified in the bootup file.
• If you did not specify a bootup file name, you can configure the other settings of the Rack Monitor 250 remotely through its Web interface or command line interface; the user name and password are both apc, by default.

To create a bootup file, see your BOOTP server documentation.


You can use an RFC2131/RFC2132-compliant DHCP server to configure the TCP/IP settings for the Rack Monitor 250.

This section summarizes the Rack Monitor 250 communication with a DHCP server. For more detail about how a DHCP server can configure the network settings for a Rack Monitor 250, see the Rack Monitor 250 User Guide.

  • The Rack Monitor 250 sends out a DHCP request that uses the following to identify itself:

- A Vendor Class Identifier (APC by default)

- A Client Identifier (by default, the MAC address of the Rack Monitor 250)

- A User Class Identifier (by default, the identification of the application firmware installed on the Rack Monitor 250) 

  • A properly configured DHCP server responds with a DHCP offer that includes all the settings the Rack Monitor 250 needs for network communication.

The DHCP offer also includes the Vendor Specific Information option (DHCP option 43). The Rack Monitor 250 can be configured to ignore DHCP offers that do not encapsulate the APC cookie in DHCP option 43 using the following hexadecimal format. The Rack Monitor 250 does not require this cookie by default.

Option 43 = 01 04 31 41 50 43


- the first byte (01) is the code.

- the second byte (04) is the length.

- the remaining bytes (31 41 50 43) are the APC cookie.

See your DHCP server documentation to add code to the Vendor Specific Information option.

The Rack Monitor 250 web interface has options to use vendor-specific data to require the DHCP server to provide an “APC” cookie. See the Rack Monitor 250 User Guide.

Local access to the command line interface

For local access, connect a computer to the Rack Monitor 250 to access the command line interface.

NOTICE: If you are unable to access the appliance using the console port, you may need to install a serial-to-USB virtual COM port driver. The USB vendor is FTDI; the driver type is VCP. Driver downloads are available on the FTDI Chip web site.

1. Select a USB port at the computer, and disable any service that uses that port.

2. Connect the provided USB A-USB mini B configuration cable from the selected port on the computer to the console port on the Rack Monitor 250.

3. Run a terminal program (e.g. 3rd party terminal emulator programs like HyperTerminal, PuTTy, or Tera Term) and configure the selected port for 9600 bps, 8 data bits, no parity, 1 stop bit, and noflow control. Save the changes.

4. Press ENTER, repeatedly if necessary, to display the User Name prompt.

5. Use apc for the user name and password.

Remote access to the command line interface

From any computer on the same network as the Rack Monitor 250, you can use ARP and Ping to assign an IP address to the Rack Monitor 250, and then use Telnet to access its command line interface and configure the other TCP/IP settings.

After the Rack Monitor 250 has its IP address configured, you can use Telnet, without first using ARP and Ping, to access that Rack Monitor 250.

1. Use the MAC address of the Rack Monitor 250 in the ARP command to define the IP address.

Note: Look for the MAC address on the bottom of the Rack Monitor 250 or on the Quality Assurance slip included in the package.

For example, to define as the IP address of a Rack Monitor 250 with 00 c0 b7 63 9f 67 as its MAC address, use one of the following commands:

– Windows command format:

arp -s 00-c0-b7-63-9f-67

– LINUX command format:

arp -s 00:c0:b7:63:9f:67

2. Use Ping with a size of 113 bytes to assign the IP address defined by the ARP command. For the

IP address defined in step 1, use one of the following commands:

– Windows command format:

ping -l 113

– LINUX command format:

ping -s 113

3. Use Telnet to access the Rack Monitor 250 at its newly assigned IP address. For example:


4. Use apc for both user name and password.

Command line interface

After you log on at the command line interface, you can manually configure network settings.

1. Contact your network administrator to obtain the IP address, subnet mask, and default gateway for the Rack Monitor 250.

2. Use this command to configure network settings.


-i yourIPaddress

-s yourSubnetMask

-g yourDefaultGateway

For each variable, type a numeric value that has the format

The command can be entered on one line. For example, to set a system IP address of, a Subnet Mask of and a default gateway of, type the following command and press ENTER:

tcpip -i -s -g

3. Type reboot. The Rack Monitor 250 restarts to apply the changes.

.INI file utility

You can use the .INI file export utility to export .INI file settings from configured Rack Monitor 250s to one or more unconfigured Rack Monitor 250s. The utility and documentation are available in FAQ article FA156117 on the APC by Schneider Electric website,
