Chapter 1 Hardware Installation
Coaxial Cable Installation
Procedure: Install Craft Interface Wires on the Backplane
Step 1
Use #22 or #24 AWG wire.
Step 2
Wrap the craft interface wires on the appropriate wire-wrap pins according to local site practice.
Note
.
Step 3
Wrap the ground shield of the craft interface cable to the frame-ground pin.
Step 4
Wrap the ground wire of your computer cable to pin A3 on the craft pin field.
1.10 Coaxial Cable Installation
Caution
Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the
wristband cable into the ESD jack located on the lower-right outside edge of the shelf assembly.

When using ONS 15454 DS-3 electrical cables, the cables must terminate on an EIA installed on the
ONS 15454 backplane. EIAs are available with SMB and BNC connectors. All DS-3 cables connected
to the ONS 15454 DS-3 card must terminate with coaxial cables using the desired connector type to
connect to the specified EIA. For information about physically installing an EIA in the field, see the
ONS 15454 backplane. EIAs are available with SMB and BNC connectors. All DS-3 cables connected
to the ONS 15454 DS-3 card must terminate with coaxial cables using the desired connector type to
connect to the specified EIA. For information about physically installing an EIA in the field, see the

The electromagnetic compatibility (EMC) performance of the system depends on good-quality DS-3
coaxial cables, such as Shuner Type G 03233 D, or the equivalent.

1.10.1 BNC Connector Installation
For a description of BNC EIAs, see the
. The BNC connectors on the
EIA supports Trompeter UCBJ224 (75 Ohm) 4 leg connectors. Right-angle mating connectors for the
connecting cable are AMP 413588-2 (75 Ohm) connectors. If preferred, you can also use a straight
connector of the same type. Use RG-59/U cable to connect to the ONS 15454 BNC EIA. These cables
are recommended to connect to a patch panel and are designed for long runs of up to 450 feet.
