1.5.6 SMB EIA
The ONS 15454 SMB EIA supports AMP 415484-1 75-ohm 4-leg connectors. Right-angle mating
connectors for the connecting cable are AMP 415484-2 (75-ohm) connectors. Use RG-179/U cable to
connect to the ONS 15454 EIA. Cisco recommends these cables for connection to a patch panel; they
are not designed for long runs. Range does not affect loopback testing.
You can use SMB EIAs with DS-1, DS-3 (including the DS3XM-6 and DS3XM-12), and EC-1 cards. If
you use DS-1 cards, use the DS-1 electrical interface adapter (balun) to terminate the twisted pair DS-1
cable to the SMB EIA (see the “1.7.2 Electrical Interface Adapters” section on page 1-38). SMB EIAs
support 14 ports per slot when used with a DS-1 card, 12 ports per slot when used with a DS-3 or EC-1
card, and 6 ports per slot when used with a DS3XM-6 card.
Figure 1-18 shows the ONS 15454 with preinstalled SMB EIAs and the sheet metal cover and screw
locations for the EIA. The SMB connectors on the EIA are AMP 415504-3 (75-ohm) 4-leg connectors.
To install SMB connectors, refer to the “Install Shelf and Backplane Cable” chapter in the Cisco ONS
15454 Procedure Guide.
