Install an OAU 2A on a wall or pole.
• Determine whether to install an OAU 2A on a wall or pole based on
actual conditions.
• If an OAU 2A needs to be installed on a tower, it is recommended that
you install it at the foot of the tower to facilitate maintenance.

Install an outdoor fiber or network cable.
The GE1(e) or GE2(e) port can be used
to transmit/receive electrical services,
and the GE3(o) or COMBO port can be
used to transmit/receive optical services.
In this example, the GE3(o) port is used.
• Connect an outdoor fiber or network cable to a port in the
maintenance compartment.
• 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.
4
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.

Connect the IF ports of the OAU 2A and each XMC ODU using an IF
cable.

Installation procedure
Before installing a cable, bind the cable section that links the cable connector
to the pole. This will protect the cable connector from damage. Ensure that
the length of cable running from the binding point to the OAU 2A is sufficient
to attach the cable connector to a service port on the OAU 2A.
