5. Rotate the transceiver until the bolts slide out of the four
grooves in the antenna bracket. (The direction of rotation
depends on the orientation of the antenna bracket—to the
right or left.) If the mounting bolts will not slide into the
grooves, loosen the bolts. See figure 10-2.
6. Cover the transceiver coupling (center hole) with a plastic
coupling plug (if available) or tape to prevent
contamination.
Installing the replacement transceiver
7. To install the replacement transceiver, follow the steps in
section 4.10 (page 4–27).
8. Connect the IFL cable to the IFL connector on the
transceiver.
9. Ground the ODU, as explained in section 4.11 (page 4–30).
10. After you replace the transceiver:
- Go to the next subsection (Replacing the antenna) only
if you need to replace the antenna.
- Apply power to the IDU chassis power supply.
- Use the CCM LCD to check the ODU status. (For
details, see section 6.10).
- Notify the EMS operator that the HT is ready to
resume service.
If you are replacing the transceiver only, you should not need to
realign the antenna.
