Chapter 3 Installation
3.8.2 High Power Amplifier (HPA)
Always install the high power amplifiers with the aid of a second
handler. The high power amplifier weighs approximately 55 lbs.
The HPA compartment frame includes eight (8) slots for the HPA’s. Please refer to Figure
3-24
, Figure 3-26 or drawings SX03-31000-02-D01 or SX03-32000-02-D01 for the mounting
position of the HPA’s.
The HPA’s should be installed in the following sequence:
1. Remove the eight (8) magnetic plates from the HPA compartment frame by
loosening the 10-32 slotted screw used to secure each plate in place.
2. Using two handlers, one located on each side of the HPA, lift the HPA and position it
level to the top-left most open space in the HPA compartment frame.
3. Carefully line up the HPA sliders (1 located on the top and 1 located on the bottom of
the HPA) with the slide rails mounted in the HPA compartment frame – see Figure
3-31
.
4. Slowly push the HPA into the HPA compartment frame until it stops.
5. There are three (3) blind mate connectors located on the HPA rear panel which are
aligned with corresponding connectors on the HPA compartment frame backplane –
see Figure 3-30
.
6. Ensure that the connectors are aligned properly and slowly push the HPA into the
backplane until it stops. At this point, the back side of the HPA front panel should be
flush with the HPA compartment frame.
7. Secure the HPA in place by tightening the 10-32 Slotted captive screw (located at the
top of the HPA front panel) with a torque rating of 15.5 Inch Lbs. – see Figure 3-31
.
8. Place the magnetic plate at the bottom of the HPA front panel and tighten the 10-32
Slotted captive screw with a torque rating of 15.5 Inch Lbs. Note: The magnetic plate
must be installed in order for the HPA to power up later on.
9. Repeat steps 2 through 8 for the remaining seven (7) HPA’s.
NOTE: Each HPA will be marked indicating which HPA compartment slot (0, 1, 2, 3, 4, 5, 6,
or 7) it should be installed in. Ensure that the HPA is installed in the correct slot.
