LDM-MR19.2
The card’s RPF circuitry will detect this tone, light the card’s RPF LED, and stop
the card from making any further attempts to communicate with the standalone.
When you see that the card’s RPF LED is lit, check the remote site; when power
has been restored, push the card’s RPF button to turn the LED off and to reset
the card for normal operation.
Only point-to-point, standalone-to-card applications can benefit from this
feature; even if RPF is enabled in card-to-card or standalone-to-standalone
applications, it will have no effect. RPF should be disabled in multipoint
applications, because it can take down the whole LDM-MR19.2 network
without pinpointing where the failure has occurred.
5.5 Turning the Unit OFF
To turn OFF the LDM-MR19.2, unplug its AC power cord (standalone units)
or turn OFF or unplug the RackNest 2/14 (card units).
5.6 Reconfiguration
If at some point you need to reconfigure the LDM-MR19.2 to operate differently—
with a new data rate or new clock source, for example—you can change the
settings of the unit’s configuration controls. Standalones: Unplug the unit, then
follow the procedure in Section 3.4. Refer to Table 3-2 on pages 22 and 23 for the
possible settings of these controls. Cards: Turn OFF or unplug the RackNest 2/14,
slide the card out of the Nest, then follow the procedure in Section 4.4. Refer to
Table 4-2 on pages 32 and 33 for the possible settings of these controls.
