The parameter "Redundancy Definition" defines which type of redundancy is installed in the chassis. This parameter is a factory setting and should be not changed by the user.
| Parameter Name | Description |
|---|---|
| none | No Redundancy is installed all cards corresponding direct to the rear connectors. |
| intern | 2 x n:1 Redundancy(n=1..4) If the chassis is equipped with these redundancy enhancement, it is possible, to use slot 3 and/or slot 8 as redundant slots. Slot 3 is the redundant link for slot 1, 2, 4 and 5 ("left slot"). Slot 8 is the redundant link for slot 6, 7, 9 and 10 ("right slot"). If redundancy is configured to "off", you can use slot 3 and 8 as normal links. On the "Config" page of the unit, you have to select for each card if it should be integrated into the redundancy switching or not. |
| extern | 2 x n:1 Redundancy(n=1..4) with external switches. This redundancy type acts in the same way as the above described, but uses external switched to perform the redundancy switching. The Chassis provides the controller interface for the switches, like a waveguide or coaxial switch. The external switching is only available on special request. |
| intern2 | The mode "intern2" combines the left and right slots and perform always the same switching of slot 1..5 and slot 6..10 and versa wise. Please refer also to Theory of Operation . |
| extern2 | This redundancy type acts in the same way as "intern2", but uses external switched to perform the redundancy switching. |
| int1to1 | If the chassis is equipped with these redundancy enhancement, it is possible, to use slot 6 to 10 as redundant slots for slot 1 to 5.. |
If the automatically redundancy switching is enabled (auto) the LFTX/RX switches automatically to corresponding redundant slot.
There are 2 switching criteria for an automatic switch-over to the redundant link:
If set the redundancy to 'manual' mode, you can switch a card to the corresponding redundant card by yourself. The automatically switching is disabled.
For the intern, extern, intern2 and extern2 the following setting can be done:
| Parameter Name | Description |
|---|---|
| Red. Manual Slot Left | Select here 1, 2, 4, 5 or none. If you choose none, slot 3 is in standby-state. With selecting 1, 2, 4 or 5 you switch the chosen slot to slot 3. |
| Red. Manual Slot Right | Select here 6, 7, 9, 10 or none. If you choose none, slot 8 is in standby-state. With selecting 6, 7, 9 or 10 you switch the chosen slot to slot 8 |
For the int1to1 the following setting can be done:
| Parameter Name | Description |
|---|---|
| Red. Manual x. Slot | Select here 1 or 2. If you choose 1, slot 1 to 5 is active. With selecting 2 the chosen slot is 6 to 10 depending on the chosen slot is 6 to 10 depending on the number "x." |
