When connected waveguide switches are equipped with inhibit contacts, it is possible to mute different connected HPA`s while a corresponding waveguide-switch is switching.
For configuring this HPA-mute-matrix, 16 DIP switches are located on the top-board of your sat-nms IO-FEP2. You can check actual settings through little windows in the top cover of your sat-nms IO-FEP2's housing. For changing configuration, you have to remove this top cover by releasing 3 screws: 2 screws on top left around RJ45 LAN connector (one above and one below this connector) and one screw on very right side of the top cover. Each of all DIP-switches represents one waveguide switch 1...16. The DIP switches position on the board correlates to the position of each switch interface connector on the mainboard. Additionally each switch is marked with its function on the board, e.g. 'HPA MUTE BY WG-SWITCH 1'. Numbers written on every DIP-switch belong to the numbers of the corresponding HPA. When a switch is in position "on", the corresponding HPA mutes, during switchover of corresponding waveguide switch.
An example: You want to mute HPA 1 or 4 or 8 when waveguide switch 2 changes its condition.
Then you have to configure on the DIP-switch marked with 'HPA MUTE BY WG-SWITCH 2' the switches 1 and 4 and 8 into the "on"-position. All the others have to remain in 'off'-position.
Another example: You want to mute HPA 1 when waveguide switch 2 or 9 or 16 changes its condition. Then you have to configure on each of following DIP-switch switch 1 to 'on'-position: 'HPA MUTE BY WG-SWITCH 2', 'HPA MUTE BY WG-SWITCH 9', and 'HPA MUTE BY WG-SWITCH 16' All the others have to remain in 'off'-position.
This hardware HPA-mute-matrix is always enabled for all 16 waveguide-switch interfaces regardless the quantity of enabled waveguide-switch interfaces by feature codes.
If connected waveguide-switches are not equipped with inhibit-contacts, your sat-nms IO-FEP2 nevertheless provides the possibility to mute connected HPA(s) during switchover triggered by software. Therefore you have to open top cover of sat-nms IO-FEP2 and switch a slide-switch with corresponding number of the HPA to 'SOFTWARE CONTROLLED HPA MUTE' position. These switches are set to 'HARDWARE CONTROLLED HPA MUTE' by factory default. They are located between the DIP switches and are marked with 'HPA 1'...'HPA 10'. This clarifies correlation to the HPA mute outputs. Afterwards you have to configure the software-muting-matrix. How to do this is described in chapter 3.4 Installation Parameters .
Setting of these switches is also displayed on the sat-nms IO-FEP2's webpage: Setup/WG switches right half of the first line shows 'Inhibit' and the numbers of each HPA mute output. When 'HARDWARE CONTROLLED HPA MUTE' is selected, a 'HW' is shown here. If nothing is displayed here, corresponding output is configured to 'SOFTWARE CONTROLLED HPA MUTE'.
This option is only available for waveguide-switch interfaces enabled by feature codes, see chapter 2.4.1 Feature code activation for further information.
A mixed configuration of hardware and software muting is possible. You have to take into account that you have to select per HPA whether to switch by hardware or by software matrix. So it is not possible to mute one HPA with a mixed configuration of hardware and software muting.
If you nevertheless have this challenge to solve, there is a solution available as well: Therefore you have to connect 2 HPA mute outputs as series connection, one triggered by software, the other one triggered by hardware.
