Replacing a Module in a Live Environment
Grass Valley recommends that the power supply is switched off and the mains connections are
removed before performing the previous operations. However, in a live environment, this may
not be possible and you can remove and install modules without switching the power off.
Replacement of the Cooling Fan Assembly
The cooling fan assembly is located on the rear panel of the 3U enclosure and may be easily
replaced without removing the rack from its mounting position or removing any cable
connections.
To replace the fan assembly:
1 Switch off the unit’s power supplies and remove the IEC power cables.
2 Remove the two 70 mm x 4 mm posi-pan retaining screws.
Note:
Ensure that the power supply is switched OFF and the mains
power connection at the rear of the unit is removed before this operation
is performed.
Note:
It cannot be guaranteed that there will be no disturbance to the
operation of other modules in the enclosure when you replace a module
without first powering down the enclosure.
