Test set overview
3.3.2 Ethernet port ETH1
Depending on the interface board of your CMC test set, the PoE Ethernet ( P ower o ver E thernet)
port ETH1 is of one of the following types:
• 10/100Base-TX (twisted pair) Ethernet port (at NET-1C board)
• 10/100/1000Base-TX (twisted pair) Ethernet port (at NET-2 board)
They support auto crossing (auto MDI/MDIX). This means you can use a standard cable or a
cross-over Ethernet patch cable.
→ Section 4.6 "Technical data of the communication ports" on page 34.
The yellow and green LEDs at the ETH port reflect the port’s operational status. Depending on your NET-
x interface board, their behavior slightly varies.

3.3.3 ! button
The ! button enables you to recover from unsuccessful software image downloads or other issues.
To start a new software image download, press the ! button with a pointed tool or a paper clip while
powering up the CMC . In that case, the test set will not start as usual but wait for a new software
image download.
3.3.4 Associate button
The Associate button has the following functions:
• Association with controlling computer
An Ethernet communication port enables you to communicate with any CMC available on the
network. This may lead to dangerous situations where a user accidentally connects to a device
located on a desk of somebody else, emitting unsafe voltages and endangering the person working
there.
To prevent such a situation, a mechanism is integrated into the
CMC test set that allows only
"authorized" clients to control the test set. If you use the Associate button, the test set is registered
for use with a specific host computer.
The association process can be initiated via the control software.
► For more details about this process, refer to the according help.
For the association, the CMC test set remembers the Ethernet hardware address (MAC) of the
connected port of the controlling device. Should the port change, a re-association is necessary.
• Reset IP configuration
If the Associate button is pressed while powering up the CMC test set, the IP configuration of the
network interfaces is reset to factory default, which is DHCP/AutoIP for both network interfaces. This
may be necessary to recover from settings with conflicting static IP addresses.
