Juniper Networks G10 CMTS Getting Started
This section describes how to interconnect up to two NIC Access Modules to multiple HFC
Connector Modules in a non-redundant configuration. The procedure assumes that a NIC
Module only supports the DOCSIS Modules installed in the same domain of the chassis.
Therefore, if five or more DOCSIS Modules are installed in the system, then two NIC Modules
are installed to support them. In addition, the procedure assumes that DOCSIS Modules are
installed in the following slot order: 1, 2, 3, 4, 10, 11, 12, 13.
In this particular procedure, the RJ-45 ports of the CCM
Access Module labeled "Eth0" and "Eth1" are unused.
The NIC Access Module cables are used to interconnect the Fast Ethernet ports of the HFC
Connector Modules to the NIC Access Module. The 12 RJ-45 connectors on the NIC Access
Module cable plugged into the connector labeled "2" on the NIC Access Module can be used
as general purpose switched FastEthernet ports. Refer to Table 1 on page 18 for details.
It is recommended that the following procedure be
followed to allow for future wiring considerations.
1.
If applicable, remove the protective cover that is inserted into the RJ-21 end of the NIC
Access Module cable.
2.
Firmly insert the RJ-21 end of the cable into the connector labeled "1" on the NIC Access
Module in slot 5 (refer to Figure 14 on page 26).
3.
Tighten the two cable retainer screws by applying 4 in lb of torque to each of the screws.
4.
Locate the RJ-45 connectors of the NIC Access Module cable labeled "PORT 5" and
"PORT 6" and plug them into the RJ-45 ports of the HFC Connector Module in slot 1
labeled "Eth0" and "Eth1," respectively (refer to Figure 12 on page 22 for port labeling).
If an HFC Connector Module is installed in slot 2, proceed to Step 5; otherwise, jump
ahead to Step 15.
5.
Locate the RJ-45 connectors of the NIC Access Module cable labeled "PORT 7" and
"PORT 8" and plug them into the RJ-45 ports of the HFC Connector Module in slot 2
labeled "Eth0" and "Eth1," respectively. If an HFC Connector Module is installed in slot
3, proceed to Step 6; otherwise, jump ahead to Step 15.
6.
Locate the RJ-45 connectors of the NIC Access Module cable labeled "PORT 9" and
"PORT 10" and plug them into the RJ-45 ports of the HFC Connector Module in slot 3
labeled "Eth0" and "Eth1," respectively. If an HFC Connector Module is installed in slot
4, proceed to Step 7; otherwise, jump ahead to Step 15.
7.
Locate the RJ-45 connectors of the NIC Access Module cable labeled "PORT 11" and
"PORT 12" and plug them into the RJ-45 ports of the HFC Connector Module in slot 4
labeled "Eth0" and "Eth1," respectively. If an HFC Connector Module is installed in slot
10, proceed to Step 8; otherwise, jump ahead to Step 15.
