Coaxial Cable Installation
Procedure: Install Coaxial Cable With High-Density BNC Connectors
Step 1 Place the BNC cable connector over the desired connection point on the backplane.
Step 2 Using the insertions tool, position the cable connector so that the slot in the connector is over the
corresponding notch at the backplane connection point.
Step 3 Gently push the connector down until the notch backplane connector slides into the slot on the cable
connector.
Step 4 Turn the cable connector until the notch clicks into place.
Step 5 Tie wrap or lace the cables to the EIA according to Telcordia standards (GR-1275-CORE) or local site
practice.
Step 6 Route the cables to the nearest side of the shelf assembly through the side cutouts according to local site
practice.
The rubber coated edges of the side cutouts prevent the cables from chafing.
1.10.3 SMB Connector Installation
The SMB backplane cover is similar to the BNC cover. For further detail, see the “SMB EIA” section
on page 1-19. The SMB connectors on the EIA are AMP 415504-3 (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 (over 50 feet). Range does not affect loopback testing.
For information about attaching ferrites to SMB/BNC connectors, see the “Ferrite Installation” section
on page 1-61.
Procedure: Install Coaxial Cable with SMB Connectors
Refer to Figure 1-26 when performing the following steps.
Step 1 Place the SMB cable connector over the desired connection point on the backplane.
Step 2 Gently push the connector until it clicks into place.
Step 3 Tie wrap or lace the cables to the EIA according to Telcordia standards (GR-1275-CORE) or local site
practice.
Step 4 Route the cables to the nearest side of the shelf assembly into rack runs according to local site practice.
