Configuring a CMM4

Attribute
Meaning
Default
Gateway
This is the default gateway of the CMM4 (controller board). The EtherWAN
Switch has a separate default gateway setting that is set using the Ethernet
Switch web or serial interface.
The default for this parameter is 169.254.0.0.
Since both the controller board and the 14-port EtherWAN switch have the
same default IP address, either may respond when using IP address 169.254.1.1
from your PC. You can configure first whichever unit responds first, as easily
determined by the distinctive web pages of the controller board or the
EtherWAN switch, or you can use
to more deterministically access
and configure the EtherWAN switch’s and controller board’s IP addresses.
Procedure 7 Configuring EtherWAN switch and Controller Board IP Addresses
1
Connect an Ethernet cable between your PC and the EtherWAN switch.
2
Disconnect the patch cable between the controller board management port and the
EtherWAN switch.
3
Enter the EtherWAN switch’s web pages using your browser and IP address
169.254.1.1 and proceed to configure the EtherWAN switch.
4
Reconnect the patch cable between the controller board management port and the
EtherWAN switch.
5
Enter the controller board’s web pages using your browser and IP address
169.254.1.1 and proceed to configure the CMM4 controller board.
6
Disconnect your PC from the EtherWAN switch.
Overriding Forgotten IP Addresses, Usernames, or Passwords
By using the toggle switch on the CMM4 controller board, you can temporarily override a lost or
unknown IP address, username, or password as follows:
•
When the toggle switch is in the “Default” position (up or towards the operator), a power
cycle causes the CMM4 to boot with the default IP address and no username or password
required. The CMM GUI displays a message indicating that the unit has been powered up in
default mode.
•
When the toggle switch is in the “Normal” position (down or away from the operator) a power
cycle causes the CMM4 to boot with your operator-set IP address, username(s) and
password(s).
