Before any changes can be done to the Ethernet configuration, a
proper Ethernet password has to be configured.
First read the "Ethernet security disclaimer" which gives access to
configure a password that must meet the following requirements:
•
minimum 8 characters
•
minimum 1 non-alphabetic character
•
minimum 1 upper case alphabetic character
•
minimum 1 lower case alphabetic character.
When a password has been created, the Ethernet can be enabled
and the IP configuration can be accessed.

Ethernet configuration
The Ethernet setup can be made in two ways:
•
Automatic DHCP
•
Manual.
DHCP configuration
A host must be entered in this display. The host name is used when
establishing an internet connection. Enter the host name in the web
browser address line.
DHCP must be enabled to establish an internet connection. The
browser will now connect to CU 362.
The user can choose to run DHCP automatically or to assign an IP
address.
Example
"Host name" is set to "CU362", and DHCP is disabled.
The IP address is 192.168.0.2, the subnet mask is 255.255.255.0,
and the standard gateway is set to 192.255.0.1.
The MAC address is 00 14 44 12 34 56.
A password is required to establish a VNC connection to CU 362.
The password can be reset.
Both username and password are factory set to "admin".

Grundfos recommends that the system administrator is
contacted to arrange security protection for the CU 362
connection.
In order to use the web server, the user must know the IP address
of CU 362. All network units must have a unique IP address to
communicate with each other. The IP address of CU 362 from
factory is 192.168.0.2.
Alternatively to the factory-set IP address, it is possible to use a
dynamic assignment of IP address. This is possible by
activating DHCP (Dynamic Host Configuration Protocol) either
directly in CU 362 or via the web server. See section about
Ethernet.
Dynamic assignment of an IP address for CU 362 requires a DHCP
server in the network. The DHCP server assigns a number of IP
addresses to the electrical units and makes sure that two units do
not receive the same IP address.
A standard internet browser is used for connection to the web
server of CU 362.
If the user wants to use the factory-set IP address, no changes are
required in the menu display. Open the internet browser and enter
the IP address of CU 362. See section about Ethernet.
Now open the browser, and enter the CU 362 "Host name" instead
of the IP address. The internet browser tries to connect to CU 362.
The host name can be read in the display, but can only be changed
using a PC Tool or via a web browser.
See section about change of network settings.
DHCP requires a host name.
