Cable a NIC Access Module

Cable a NIC Access Module
This section describes how to interconnect up to two NIC Access Modules to multiple HFC
Connector Modules or SIMs. The procedure assumes that a NIC Module supports only the
DOCSIS Modules installed in the same domain of the chassis. Therefore, if five or more
DOCSIS Modules are installed in the system, two NIC Modules are needed 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.
The NIC Access Module cables are used to interconnect the Fast Ethernet ports of the HFC
Connector Modules or SIMs to the NIC Access Module.
You can use four of the RJ-45 connectors on the NIC Access Module cable plugged into
connector
2 on the NIC Access Module as Fast Ethernet interfaces. See Table 39 on page 118
for more information.
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 (see Figure 17 on page 49).
3. Tighten the two cable retainer screws by applying 4 in-lb of torque to each of the screws.
4. Locate the PORT 5 and PORT 6 connectors of the NIC Access Module cable and plug
them into the Eth0 and Eth1 ports of the HFC Connector Module or SIM in slot 1 (see
Figure 18 on page 51 and Figure 20 on page 54 for port labeling). If an HFC Connector
Module or SIM is installed in slot 2, proceed to step 5; otherwise, proceed to step 15.
5. Locate the PORT 7 and PORT 8 connectors of the NIC Access Module cable and plug
them into the Eth0 and Eth1 ports of the HFC Connector Module or SIM in slot 2. If an
HFC Connector Module or SIM is installed in slot 3, proceed to step 6; otherwise,
proceed to step 15.
6. Locate the PORT 9 and PORT 10 connectors of the NIC Access Module cable and plug
them into the Eth0 and Eth1 ports of the HFC Connector Module or SIM in slot 3. If an
HFC Connector Module or SIM is installed in slot 4, proceed to step 7; otherwise,
proceed to step 15.
7. Locate the PORT 11 and PORT 12 connectors of the NIC Access Module cable and plug
them into the Eth0 and Eth1 ports of the HFC Connector Module or SIM in slot 4. If an
HFC Connector Module or SIM is installed in slot 10, proceed to step 8; otherwise,
proceed to step 15.
If you are using internal chassis Fast Ethernet wiring (using
a version 2 chassis and SIMs), do not attach any cables to
the NIC Access Module.
We recommend you follow this procedure to allow for
future wiring considerations.
