Replacing a Module in a Live Environment
Grass Valley recommends that the mains connections are removed before performing the
operations described above. However, in a live environment this may not be possible, so the
modules are designed to be removed and installed without switching the power off.
:
Note:
Ensure that the mains power connection at the rear of the unit is
removed before these operations are performed.
Note:
Ensure that the mains power connection at the rear of the unit is

without first powering down the enclosure.
