When using this procedure to replace or remove the transmit filter, the warning applies and you
must power down the site before starting the replacement procedure if the entire site is connected to the
Transmit filter being removed. Powering down the site causes any affiliated subscribers to relocate to
another channel at an adjacent site. It is recommended that you disable the channels before powering down
so that the system does not attribute the loss of channel to a failure. You can disable a channel using the
Unified Event Manager, or the Configuration/Service Software (CSS).
