Inserting an RHU/AO Module in to QX Chassis I P/N 709C011101 I Page 14
3.3 Inserting an RHU/AO Module in to QX Chassis
The QX chassis and Remote Hub Unit (RHU) and Add-On (AO) modules are provided separately,
whereas the modules must be inserted in to the chassis. This requires opening the QX chassis
front panel door and inserting the modules into their respective slots.
The RHU/AO modules are hot swappable and can be inserted either before or after the system
installation.
To insert an RHU/AO Module
1. Open the QX door, by unscrewing the two captive screws.
QX Front Door Screws Figure 3-1
2. Referring to the slot allocation labels inside of the chassis door, position the service module
in the relevant slot with the handle facing front. Refer to Figure
3-2.
IMPORTANT!
Dummy modules must be inserted in unoccupied slots for termination.
Slot Allocations for Service Modules Figure 3-2
NOTE 1: Termination modules are required for unoccupied slots – ordered separately.
NOTE 2: When installing an LTE AO unit, an indication of the use of an internal or external filter must be
selected – via the GUI.
3. Slide the module towards the back of the unit and fit the module ejectors in to the side
notches of the slot (verify that the screws are unscrewed). Refer to Figure
3-3.
