The COM46 cards take between 2 and 3 minutes to reach a fully functional state after a reboot
or power-up. The status of the card can be tracked during this time by observing the behavior of
the LEDs.
Normal LED behavior during startup is listed below in Figure 73.

Note: It is normal for the Tuner LEDs to turn on and off during guide acquisition as they
register with the SWiM. If a Tuner LED (other than 9) is flashing, the tuner is locked to a
transport but is unable to stream video. Check the configuration settings.
If the guide acquisition state lasts longer than expected without the Tuner LEDs turning on, then
the system is probably having difficulty acquiring the APG (Advance Program Guide). In this
case, it is recommended that the installer verify proper and healthy RF levels being fed into the
RF Distribution panel. The card may appear to "forget" its old settings during this time, but they
should reappear once the situation has been remedied.
Upon successful boot-up, a COM46 will revert to its previously configured channel lineup. The
lineup is specified either by the external control server (if applicable) or automatically from the
cards themselves if the persistence setting was left enabled when the system was configured
(persistence is enabled by default).
