Installing an RF power module
1. If possible, turn off the transmitter before installing an RF power module. 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. Verify the RF power module is fully inserted by ensuring the
faceplate of the RF power module is touching the transmitter chassis that it mates
with.
3. Install both mounting screws in the RF power module’s front panel.
4. Connect the PDM cable (RJ45 connector) to the front of the RF power module.
5. If the RF power module was disabled through the AUI, enable it as follows:
• From the Meters page, click on the Modules - Rack information (i) button. The
Power Module status screen (see Figure 1.5 on page 1-52 ) should appear. Click on
the associated RF power module’s Front Panel Inhibit icon. The icon colour
should change from red to green, indicating the RF power module is enabled.
You should hear a relay in the back of the transmitter pick up (energize).
6. If the RF power module being installed is a replacement, upgrade the subsystem
software using the AUI’s
Upgrade Software
page under the
System Settings
menu by
running an upgrade using the existing .tgz file already installed on the transmitter. See
the NX50 Operations and Maintenance Manual for detailed instructions
