3.2.8 FL IF MEM 2TX-D
The interface module has two twisted pair interfaces in addition to the parameterization
memory. To distinguish it from other 2TX interface modules, it is supplied in charcoal-gray
housing. The parameterization memory is used to store device data, which is modified by
the user and stored retentively.
3.2.8.1 Parameterization Memory Default Upon Delivery
By default upon delivery, the parameterization memory is empty (see "Default Upon
Delivery/Default Settings" on page 3-1).
3.2.8.2 Twisted Pair Interface Default Upon Delivery
When the interface modules are inserted, the auto negotiation and auto crossing functions
are activated. Link monitoring for the twisted pair ports is not activated.
3.2.8.3 Function of the Memory Module
– When saving data to the Flash memory of the device, the data is also transmitted to a
plugged-in memory module.
– Data is stored to the Flash memory of the head station and in the memory module:
- After a system startup
- On request by the user
Make sure that only one memory module is inserted. If more than one module is inserted,
the switch indicates error code "87" on the display. Remove all but one of the memory
modules and restart the switch.
The memory module is supported by firmware Version 2.03 or later. Firmware
Versions < 2.03 treat the memory module as a "standard" FL IF 2TX VS-RJ.
The use of memory modules requires the application of system bus firmware 4.20 or later
in the head station. The system bus firmware for your head station is displayed on the
"Device Information/General" web page.
Hot plugging
When inserting and removing interface modules, you do not have to switch off the supply
voltage. The interface modules are detected automatically and logged to the network
management.
If the module is removed when saving, the configuration is not saved. The saving
procedure is finished as soon as the display no longer indicates "SC" or when the status
"Current Configuration was saved" is indicated on the "Configuration Management"
web page.
If an interface module is inserted in an MMS that has already been parameterized, the
existing configuration remains active.
If the user resets the module to the settings default upon delivery, the configuration is
also saved on the memory module. See "Default Upon Delivery/Default Settings" on
page 3-1.
