Procedure
Step 1 Connect the RJ45 connector at one end of the Ethernet cable to the PoE port on the pRRU
panel, and push the cables into the cable clips.
Step 2 Optional: Connect the RJ45 connector at the other end of the Ethernet cable to the output
port of the Extender. Then, connect the RJ45 connector at one end of another Ethernet cable
to the input port of the Extender.
In this scenario, the Ethernet cable is divided into two parts, one between the RHUB and the
Extender and the other between the Extender and the pRRU.
Step 3 Connect the RJ45 connector at the other end of the Ethernet cable to any port ranging from
CPRI_E0 to CPRI_E7 on the RHUB panel based on the engineering design, as shown in
Figure 9-28.

Ethernet cables are not delivered, and they must be prepared onsite. You need to use a
network cable tester to test the Ethernet cable connection.
The Ethernet cable has the following functions:
− Provides power supply for the pRRU when the cable connects the CPRI_E0
port on the pRRU to the RHUB.
− Transmits CPRI signals between an RHUB and a pRRU.
