Configuration
8.1
General
Basic configuration of the Liquid Cooling Package,
particularly the (one-off) adjustment of the network
settings, may be carried out in various ways:
1. HTTP connection via the Ethernet interface
2. Telnet connection via the Ethernet interface
3. Serial connection via a USB cable
The settings are generally made via an HTTP connec-
tion. If this is not possible, for example because ac-
cess via HTTP or HTTPS has been deactivated, we
recommend access via a Telnet connection. To this
end, as with access via an HTTP connection, the IP
address of the CMC III processing unit (hereafter re-
ferred to as CMC III PU) integrated into the Liquid
Cooling Package must be known. If this address is not
known, the device may be accessed directly via the
USB/serial interface on the front.
The following descriptions assume that the Liquid
Cooling Package, and in particular the CMC III PU,
are in their delivered state, i.e. that no changes have
been made to the basic configuration. In particular,
the connection types "HTTP" and "Telnet" must not be
blocked.

HTTP connection
8.2.1
Making the connection
Using a network cable, connect the device to your
computer via the Ethernet interface.
Change your computer's IP address to any address
within the range 192.168.0.xxx, e.g.
192.168.0.191
.
The device's preset address
192.168.0.190
must
not be used.
Set the subnet mask to the value
255.255.255.0
.
If applicable, switch off the proxy server in the
browser to facilitate a direct connection to the de-
vice.
In the browser, enter the address
http://
192.168.0.190
(fig. 48, item 1). The log-on dialogue
for registering the device will appear.

8.2.2
Changing the network settings
As a general rule, during the course of commission-
ing, the network settings of the CMC III PU will only
need to be changed once, so that it is linked into your
network structure.
In the left-hand section of the overview window, click
on the
Processing Unit
entry (fig. 49, item 3) and in
the right-hand section, click on the
Configuration
tab (fig. 49, item 4).

, click on the

but-
ton (fig. 49, item 5).
Note:
The assembly and operating instructions
for the CMC III PU contain detailed informa-
tion on how to connect via a Telnet or serial
connection.
Note:
Depending on your computer, you may
need to use a crossover cable.
