3.4.3 Configuring master/slave mode

Using the sat-nms LFTX/RX in master/slave mode provides the possibility to synchronize two chassis. In this mode, the states and values of the slave is displayed on the master's website and front panel display. And on the slave's website and front panel display the master's values and settings are displayed as well.

It is possible to change the slave's settings via the master unit and vice versa.

For using the redundancy switching option, the units must run in master slave mode in order to ensure the correct function of the redundancy function of the optical link.

To configure the master/slave mode, you have to consider the following order of setup-steps:

Slave unit :

Set the slave unit to the desired IP address. How to do this is written in chapter Setting the IP address .
Set the parameter 'Chassis Type' of the future slave unit to 'Slave' see Setup-Page .
Now select the communication type between master and slave (RS232 or HTTP, see Setup-Page ).
Type in the IP or RS232 address of the corresponding master unit. see Setup-Page

Master unit :

Set the master unit to the desired IP address. How to do this is written in chapter Setting the IP address .
Set the parameter "Chassis Type" of the future master unit to "Master". see Setup-Page .
Now select the communication type between master and slave (RS232 or HTTP, see Setup-Page ).
Type in the IP or RS232 address of the corresponding master unit. see Setup-Page

General :

Now connect both chassis via IP network or via RS232 cable. The communication fault will no more be displayed. Instead of the communication fault, you can see the settings and the parameters of the corresponding chassis on the website and on the front panel display.
After that you can do the required configuration of both units. The configuration of the slave will be saved on the slave unit and on the master unit as well.

ATTENTION : If you change the configuration of the slave unit without an existing connection to the master unit, all these settings will be over-written by the Master unit on accomplishing the Master/Slave communication the next time.
