3.14 Electrical Interface Assembly Replacement
Electrical interface assemblies (EIAs) provide cable connection points on the back of the ONS 15454
and come in several configurations that work with different cards and connections (see Table 3-1). For
more information about EIAs, see the “Installation” chapter of the Cisco ONS 15454 Installation and
Operations Guide.
EIAs have two sides. As you face the rear of the ONS 15454 shelf assembly, the right-hand side is the
A side and the left-hand side is the B side. You can install EIAs on one or both sides of the ONS 15454
backplane in any combination. For example, you can use an AMP Champ EIA on side A and a BNC EIA
on side B. The top of the EIA connector columns are labelled with the corresponding slot number, and
EIA connector pairs are marked Tx and Rx to correspond to transmit and receive cables. EIAs come
pre-installed on the ONS 15454 when ordered with the node.
