7.1 Scope
This section describes the connectors and cables of the Plexus 9000.
7.2 Overview
The Telica Plexus 9000 features a midplane design, with IOMs,
processing modules, and switching modules installed from the front and
all physical facility traffic terminations connected on passive rear IOMs.
All electrical interfaces are located on the rear of the unit, while fiber is
cabled to the front or rear depending upon the type of IOM.
Each of the front interface modules is paired with a rear module that
contains the physical interface, allowing all signal cabling to be installed
from the rear of the unit.
At the lower rear of the chassis are -48 Vdc power A and B feeds. The
shelf provides independently replaceable line filters for each power input.
Chassis grounding is also supplied in this area.
Cable management is built into the top rear of the shelf to facilitate
dressing interface cables up and to the sides of the bay. This provides neat
and secure dressing for all cable types including 22-gauge twisted pair.
