Removing and reinstalling RF power modules
Removing an RF power module
1. Confirm the location of the RF power module that is being removed. Note the alarm text
includes a Module number (1-2) that is not identified on the RF power module. See
Figure 1.3 on page 1-30 to determine the location for a given RF power module (1 - 2).
2. Set the switch on the front of the RF power module to its ‘down’ position. This inhibits the
module’s associated pair of power supply modules.
3. Remove the two M5 securing screws in the front of the module. If necessary, remove the two
M8 shipping screws in the back of the module (the shipping screws do not need to be
reinstalled, and may have already been removed during installation or previous maintenance).
4. Grasp the handle on the front of the RF power module and carefully pull the RF power
module out of the transmitter. The module weighs 17 kg (38 lbs).
Installing an RF power module
1. Grasp the handle on the front of the RF power module and insert it into the transmitter.
2. Carefully push the RF power module into place so that its card-edge connector mates with
the transmitter.
3. Install both M5 securing screws in the RF power module’s front panel.
4. Set the switch on the front of the RF power module to its ‘up’ position.
5. Press the
Reset button on the AUI to enable the RF power module and its two associated
power supplies.
WARNING:
Rotating parts are present at the bottom of the RF power module. Take
care when removing the module.
