IMPORTANT
Ensure that the redundant mod/demod installation is complete prior to activating any
traffic mods/demods, because an active unit is going to be polled regularly by the
switch.
1 Go to the CONFIG, ACTIVE menu.
2 Activate all desired traffic Mods/Demods.
After ENTER is pressed, the Switch Status LED briefly turns red. The switch then polls each
of the activated Mods/Demods, and programs the bridged Mod/Demod configuration into the
redundant Mod/Demod.
Once the programming is completed successfully, the red LED turns green.
Note: The Demod takes several seconds to configure. If the LED remains red, check the
communication status using the (MONITOR: COMM-STATE) menu.

The LEDs are arranged in columns corresponding to each modulator and demodulator,
and should accurately reflect the status of each.
1 Verify that the Status LED for each modulator and demodulator shows a green light,
indicating no faults.
2 Verify that the Online LED is lit for all connected TMIs.
3 Verify that the Online LED is not lit for the redundant Mod/Demod (for systems not using the
CRS-280 IF switch).
4 Verify that the Bridge LED is lit for only one traffic Mod/Demod.
