Chapter 3 Installing a Cisco 6260 with a POTS Splitter Configuration
Installation Procedures
See
Figure 1-4
for an illustration of an E1 subtending network configuration.
3.2.15.3 Connect the OC-3c Subtending Network Configuration
Connections for OC-3c subtending are made from the faceplate of the OC-3c/OC-3c NI-2 card installed
in the subtending host chassis to the faceplate of the OC-3c/OC-3c NI-2 card installed in the subtended
node chassis. See
Figure 1-18
for the location of theOC-3c subtending connectors on the faceplate of the
NI-2 card.
To cable the Cisco 6260 system for OC-3c subtending, complete the following steps:
Step 1
Locate the TRNK 1 network interface connectors (TX and RX) and the subtend (SBTD) 2 interface
connectors (TX and RX) on the front of each OC-3c/OC-3c NI-2 card.
Step 2
Attach an OC-3c fiber-optic cable to the SBTD 2 TX interface connector on the NI-2 card installed in
the subtending host chassis.
Step 3
Attach the other end of the cable to the TRNK 1 RX interface connector on the NI-2 card installed in the
subtended node chassis.
Step 4
Attach an OC-3c fiber-optic cable to the SBTD 2 RX interface connector on the NI-2 card installed in
the subtending host chassis.
Step 5
Attach the other end of the cable to the TRNK 1 TX interface connector on the NI-2 card installed in the
subtended node chassis.
Step 6
To cable your system for APS link redundancy, repeat
Step 1
through
Step 5
for the secondary NI-2 cards
installed in slot 11 of each host and subtending chassis.
See
Figure 1-5
for an illustration of an OC-3c subtending network configuration.
3.2.16 Connect the Ethernet to the Management Network
Warning
The ports labeled "ENET," "CNSL," and "AUX" are safety extra-low voltage (SELV) circuits. SELV
circuits should be connected only to other SELV circuits. Because the DSL circuits are treated like
telephone-network voltage, avoid connecting the SELV circuit to the telephone network voltage (TNV)
circuits.
Timesaver
We recommend that you label each data cable at both ends to identify its destination.
Complete the following steps to connect the Ethernet to the management network:
Step 1
Connect the Ethernet cable to the NI-2 card ENET receptacle (see
Figure 1-18
for the location of the
ENET receptacle on the faceplate of the NI-2 card).
Note
See
Table 2-4 on page 2-16
for cable and ferrite requirements.
