CAUTION For Jupiter-controlled routers, replacing an HO-33120 output board
that is part of a protected path scheme will cause a momentary loss of
video on the active output. In other words, video will be lost on the
board not being replaced.This interruption will continue for several
seconds. Maintenance personnel should therefore plan on such replace-
ment only when the protected output is not being used on air.
