Chapter 1 Overview
SMB Cables
Ordering Cables
You must order cables separately with the 6E3 line card when you order a Cisco 7304 router. Cables are
not automatically included with the 6E3 line card. Be sure to specify the type of cable you want shipped
with your card,
• 2CBLE-SMB-BNC-M [male]
• 2CBLE-SMB-BNC-F [female])
Building Your Own Cables
You can build your own cables for the 6E3 line card by using the cable components listed in Table 1-3.
All three cables have an SMB connector at one end to connect to the 6E3 line card. The two
SMB-to-BNC cables in Table 1-3 differ only in that one terminates in a male BNC connector, while the
other terminates in a female BNC connector. You can use the back-to-back cable for directly connecting
two closely-spaced 6E3 line cards back-to-back. These cables should be shielded and have SMB
connectors on both ends.
Note Back-to-back configurations, (6E3 line card serial port-to-6E3 line card serial port configurations)
require a specially built SMB-to-SMB cable. Table 1-3 provides cable connector specifications. Or you
can use the 2CBLE-SMB-BNC-M 10-foot (3.048 meters) shielded cable and the 2CBLE-SMB-BNC-F
10-foot (3.048 meters) shielded cable connected together.
You can order the SMB-to-BNC cables from Cisco as product numbers 2CBLE-SMB-BNC-M (male) or
2CBLE-SMB-BNC-F (female) BNC terminations, respectively. Cisco does not sell the SMB-to-SMB
cable.
Caution Cisco assumes no responsibility for system operation with other than Cisco-supplied adapter cables. The
customer is responsible for ensuring that any customer-built cables meet all of the applicable compliance
requirements (see the “Related Documentation” section on page viii.
