6.6 Installing Interconnection Cable at Control Plane
Context
It implements the connection from control plane of internal resource shelf & switching shelf
to CHUB of control shelf via Ethernet interface.
Its cable structure is shown in
Figure 6-18 Structure of Control-plane tandem cable
The cable is FTP CAT5E shielded data cable, with DB44 pins at end A and 8P8C straight
cable crimping connector at end B.
Steps
1.
Connect End A of the cable.
l
When using 040501 version of CHUB rear board, end A of the cable connects
one of FE1-8, FE9-16, FE17-24, FE25-32, FE33-40, and FE41-46 on rear board
RCHB1 or RCHB2.
l
When using 040502 version of CHUB rear board, end A of a cable connects one
of Odd FE1~15, Odd FE17~31, and Odd FE33~45 on rear board RCHB1, and
end A of the other cable connects one of Even FE2-16, Even FE18-32, and Even
FE34-46 on RCHB2. That is, if end A of a cable connects with Odd FE1~15 on
RCHB1, end A of the other cable connects Even FE2-16 on RCHB2, as so on.
2.
Connect End B of the cable.
l
When using 040501 version of CHUB rear board, end B1~B8 are divided into four
groups. End B2n-1 and End B2n (n=1~4) are in the same group. Each group can
connect to a shelf, providing two physical interfaces.
Taking end B1 and B2 as an example, there are 3 cases as follows.
à
In case of being connected with a resource shelf, end B1 is physically located
at the silk-screen identifier FE-C1/2 on one RUIM1 board, while end B2 is
