DUKE HS2 PHUs – DHCP or STATIC ASSIGNMENT

Below are the two processes to set a PHU to either DHCP or assign STATIC details.  Determination of what to use depends on if the Chef and PHUs are on a DHCP server or a managed network.

STATIC IP

• Save the file “SSI_CMD.XML” file to a root directory of a blank USB drive.
• Open “SSI_CMD.XML” file on laptop/PC with NOTEPAD or text editor.
• Edit file to change the IP, GATEWAY, and NETMASK to the desired settings such that the PHU will be recognized on your network.  This will need to be on the same network as CHEF.

Here is an example of the editable contents of the SSI_CMD.XML file (filename should NOT change from SSI_CMD.XML):

<REQ><TYPE>SSI</TYPE><IP>192.168.1.100</IP><SM>255.255.255.0</SM><SG>192.168.1.1</SG></REQ>

Legend:

IP ADDRESS – Input PHU IP

NETMASK – Same as CHEF NETMASK

GATEWAY – Same as CHEF GATEWAY

• Save the edited “SSI_CMD.XML” file to the root directory of the blank USB drive.
• Disconnect Cat5 cable from PHU.
• Turn PHU on.
• Allow displays to move beyond “spinning bars” and display either temperature or product names.
• Insert USB drive.
• Within 20 seconds, displays should go to “spinning bars”.
• Remove USB drive.
• Delete any files other than SSI_CMD.XML that may have written to the USB drive. 
• EDIT details on the SSI_CMD.XML file and repeat load for the next PHU.

DHCP Mode

• Save the file “SSI_CMD.XML” file to a root directory of a blank USB drive.
• Open “SSI_CMD.XML” file on laptop/PC with NOTEPAD or text editor.
• Set IP to 255.255.255.255 for DHCP 
• Save the edited “SSI_CMD.XML” file to the root directory of the blank USB drive.
• Disconnect Cat5 cable from PHU.
• Turn PHU on.
• Allow displays to move beyond “spinning bars” and display either temperature or product names.
• Insert USB drive 
• Within 20 seconds, displays should go to “spinning bars”.
• Remove USB drive.
• Delete any files other than SSI_CMD.XML that may have written to the USB drive. 
• Repeat for each remaining PHU at the restaurant that requires DHCP.

Regardless if PHUs are set to DHCP or STATIC, after performing the above, the PHU should be able to be seen on a network scan.  IPs or MAC addresses can then be input into the PHU setup on the Chef Portal.

Duke PHUs will have one of the 4 starting MAC address ranges:
