7.4 Establish connection to the Web server
The CIM 500 module can be configured using the built-in Web
server. To establish a connection from a PC to CIM 500 the
following steps are required:
• Connect the PC and the CIM 500 module using an Ethernet
cable.
• Configure the PC Ethernet port to the same subnetwork as the
CIM 500, e.g. 192.168.1.101, and the subnet mask to
255.255.255.0. See section A.1 How to configure an IP
address on your PC on page 90.
• Open a standard Internet browser and type 192.168.1.100 in
the URL field.
• Log in to the Web server using:

For further information how to use the Web server, see section
A.2 Web server configuration on page 90.
7.5 Status LEDs
The CIM 500 Ethernet module has two Status LEDs, (LED1 and
LED2).
See fig. 15.
• Red/green status LED (LED1) for Ethernet communication
• Red/green status LED (LED2) for internal communication
between the CIM 500 and the Grundfos product.

LED2
7.6 DATA and LINK LEDs
The CIM 500 Ethernet module has two connectivity LEDs related
to each RJ45 connector. See fig. 15.
DATA1 and DATA2
These yellow LEDs indicate data traffic activity.
LINK1 and LINK2
These green LEDs shows whether the ethernet cable is properly
connected.
User Default: admin.
Password Default: Grundfos
User and password may have been changed from
their factory default values.
TM05 6436 4712
Both ETH1 and ETH2 can be used to establish a
connection to the Web server.
The web server can be accessed while the selected
Industrial Ethernet protocol is active.
