Install the joining kit on the XMC ODU.
Install the XMC ODU on the OAU 2F.
3
Install the joining modules of the XMC ODU and
OAU 2F on the antenna.
When the XMC-3/3H ODU is used, first install the
joining modules of the XMC ODU and OAU 2F on
the hybrid coupler together with the other XMC
ODU, and then install the coupler on the antenna.
When the XMC-5D ODU is used, install the
joining modules of the XMC ODU and OAU 2F on
the dual coupler, and the install the dual coupler
on the antenna.
In the example integrated installation, the XMC-5D
ODU is used.
4
Install an IF cable. Connect the IF ports of the OAU 2F and XMC ODU using an IF cable.
For the method of making and laying out an IF cable, see the RTN XMC ODU Quick Installation
Guide.
Do not remove or insert an IF cable connector from or to the OAU 2F with power on. Otherwise,
human injuries may be caused.
Install an outdoor fiber or network cable.
5
Connect an outdoor fiber or network cable to a port.
Lay out the outdoor fiber or network cable.
Attach a yellow label to the fiber or network cable, and write a number on the label
according to the plan.
6
Install a DC power cable.
Connect a DC power cable to the DC power port in the maintenance compartment.
Lay out the DC power cable.
Select ground points for the DC power cable, and install ground clips.
Attach a matte white label to the DC power cable.
