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.
Cables of Category 5e (enhanced) or higher specification is used for connecting the RHUB
and pRRU. With the internal PoE module providing power, the distance of the pRRU and
RHUB can be extended by the Extender up to a total distance of 100 m. With the Extender,
the distance of the pRRU and RHUB can be extended by the Extender up to a total distance
of 200 m.
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.
Provides Wi-Fi services for the pRRU when the cable connects the GE port on the pRRU
with three transmission ports to the AC.
NOTE
l A pRRU can have two transmission ports or three transmission ports, requiring the same installation
operations. This section uses the pRRU with three transmission ports as an example.
l Using the CPRI_E1 port on the pRRU has the same Ethernet cable connection to the RHUB as using
the CPRI_E0 port. The following section describes the connection using the CPRI_E0 port.
Remove the dustproof cap of the CPRI_E0 port on the pRRU.
Connect the RJ45 connector at one end of the Ethernet cable to the CPRI_E0 port on the
pRRU panel.
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.
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
5-39.
Remove the dustproof cap of the GE port on the pRRU.
Connect the RJ45 connector at one end of the Ethernet cable to the GE port on the pRRU
panel.
