4.4.6 Installing an Ethernet Cable
This section describes how to install an Ethernet cable.
Prerequisites
l
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.
l
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.
Context
The Ethernet cable has the following functions:
l
Provides power supply for the pRRU when connected to the CPRI_E0 port on the pRRU.
l
Transmits CPRI signals between an RHUB and a pRRU.
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.
Procedure
Step 1
Remove the dustproof cap of the CPRI_E0 port on the pRRU.
