12.6 Restoring the Default IP Address for 1RU (3200).
12.6.1 Resetting IP address using USB Cable
The Switch+MMI module control can be accessed via Ethernet over USB. A USB A/A cable
(standard-A type connector in both ends) should be connected between a PC and the MMI
module.
To access the MMI a driver for RNDIS Ethernet gadget must be installed.
On a Windows PC the driver can be installed automatically over Windows Update, or it can be
downloaded manually. The Switch+MMI module can then be accessed directly from a web
browser, using the IP address 169.254.254.254.
All MMI functionality is supported over this interface.
12.6.2 Resetting IP address with DIP switch:
It is possible to restore to the factory-configured IP address on the Switch+MMI module. This
can be useful if the software-configured IP address is lost. The restore is done by setting DIP
switch 2 to ‘ON’ on the Switch+MMI card. When the setting has been applied, the MMI will be
configured according to the tables below regardless of what is stored in memory.
The default IP settings are:
IP Address
192.168.1.100
Subnet Mask
255.255.255.0
Default Gateway
192.168.1.1
After setting the DIP switch the MMI card has to be rebooted. The factory default IP settings will
be active as long as the setting is present. While the DIP switch on, all IP parameters in
memory can be changed and saved via the web interface. Once the DIP switch is changed
back to OFF and the card is rebooted, the IP settings in memory will be activated.
In order to remove the module, the following procedure must be followed:
1. Loosen the thumb screws for the fan assembly and remove the fans
2. Loosen the thumb screws on the MMI module
3. Press on the Switch-MMI module to come out little.
4. Take out complete Switch-MMI module.
5. Set DIP Switch 2 = ON
6. Replace both MMI and fan assembly
