7.4 Establishing connection to the webserver
You can configure CIM 500 using the built-in webserver. To
establish a connection from a PC to CIM 500, the following steps
are required:
• Connect the PC and CIM 500 using an Ethernet cable.
• Configure the PC Ethernet port to the same subnetwork as
CIM 500, for example 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 61.
• Open a standard internet browser and type 192.168.1.100 in
the URL field.
• Log in to the webserver:

For further information on how to use the webserver, see section
A.3 Login on page 62.
7.5 Status LEDs
The CIM 500 Ethernet module has two status LEDs: LED1 and
LED2. See fig. 24.
• Red and green status LED1 for Ethernet communication
• Red and green status LED2 for internal communication
between CIM 500 and the Grundfos product.

7.6 DATA and LINK LEDs
The CIM 500 Ethernet module has two connectivity LEDs related
to each RJ45 connector. See fig. 24.
DATA1 and DATA2
These yellow LEDs indicate data traffic activity.
LINK1 and LINK2
These green LEDs show whether the Ethernet cable is properly
connected.
Username Default: admin
Password Default: Grundfos
Username and password may have been changed

You can use both ETH1 and ETH2 to establish a
connection to the webserver.
You can access the webserver while the selected
Industrial Ethernet protocol is active.
