Embedded PoE Switch Management

The DW Blackjack CX is an Ubuntu Linux based recording server that features an embedded PoE switch that has been integrated with the system. Through the embedded PoE switch, users can connect and power IP cameras directly from the server hardware.

Because the DW Blackjack CX has more than one network segment within a logical network, an IP bridge is used to separate the computer from the cameras on the PoE switch.

This article will outline how to change the bridge IP address, adjust the DHCP IP range of the PoE switch, how to check the status of the DHCP server and power cycle the PoE switch.

 

Supported/Affected Devices:

• DW Blackjack CX Server Series

 

PoE Switch IP Bridge and DHCP Management

Part 1: Changing the Bridge IP Address

The bridge IP address is the address that is assigned to the embedded PoE switch to identify within the logical network. Like all IP addresses, it is important that this address is not duplicated and occupied by any other devices to avoid encountering an IP address conflict. While not always necessary, there may be scenarios where the address of the bridge may need to be altered.

To change the Bridge IP address:

1. From the Ubuntu desktop, open the Terminal application (CTRL+ALT+T) and enter the command:

 

2. The Network Connections editor will display.

Double-click on “Bridge connection 1”.

 

3. Select the “IPv4 Settings” tab

4. Customize the “Address” and “Gateway” fields as needed for your network. For example, if your network used a subnet of 192.168.1.x, you would set the IP bridge address accordingly.

 

5. Click the Save button to save the changes.

 

Part 2: Restart the Bridge

After changing the bridge IP configuration, use the Terminal application (CTRL+ALT+T) to restart the bridge with the command:

 

Part 3: Setting the DHCP IP Address Range

To adjust the DHCP range of IP addresses that are assigned to IP cameras that are directly connected to the embedded PoE switch:

1. In the Terminal application (CTRL+ALT+T) enter the command:

Enter the sudo password to the system:

• • Default dwuser root password: Dw5pectrum

 

2. The nano editor will display. You can change the DHCP range by editing the three lines below.

**NOTE: The configuration may vary depending on your local network. Consult with your network administrator if you are unfamiliar with the network requirements.

 

 

3. After editing the IP range and DHCP settings, press the CTRL+O keys to save the file then press the ENTER key.

 

4. Press the CTRL+X keys to exit.

 

Part 4: Restart the DHCP Server

After making changes to the DHCP Server, use the Terminal application (CTRL+ALT+T) to restart the DHCP Server with the command:

 

Part 5: Check the DHCP Server Status

To check the status of the DHCP Server:

1. Using the Terminal application (CTRL+ALT+T) enter the command:

 

2. The DHCP service should show as “active”.

 

Part 6: Power Cycle the PoE Switch with the PoE Utility

To power cycle the PoE switch:

1. Locate and open the “PoE_Utility” folder located on the desktop.

Open the PoEUtility shortcut.

 

2. In the “Group 1” tab, click on the “Reset power for all ports” button to cycle power for all PoE ports in the embedded switch.

The status of each port should change from “on” to “off”, then back to “on”.

 

3. Select the “Group 2” tab and repeat the previous step.

 

This completes the IP bridge and DHCP management guide for the DW Blackjack CX.
