To install the Redundant I/O system, you need the following additional
materials:
CATV grounding blocks or bulkhead coaxial connectors to install at
each RCC and RBC to shunt noise on the coaxial cable shield to ground
Semi-rigid coaxial cable (two sizes) to use for trunk line(s) and for drop
lines
CATV taps to insert in the trunk distribution cable to provide drops
from the active and stand-by controllers to the RBCs
Taps and splitters to distribute the signal from the active RBC (either
Trunk A or B) to the stand-by RCC and the active RCC
Semi-rigid coaxial cable fittings to connect trunk distribution cable to
tap housing
F-type connectors to connect drop cable to tap housing
Terminators to install on all unused terminals on a multi-drop tap
To help avoid potential damage to equipment and/or personal
injury, install redundant I/O components in a non-hazardous
location. For example, ensure that flammable gases are not present
before inserting or removing RBCs or power supplies.
In order to prevent disruption of the I/O channel, disconnect the
coaxial cable before removing or installing an RBC.
To install the Redundant I/O components:
1. Plug an RBC into each of the two designated slots and tighten the top
and bottom screws on each unit. The RBC in the right slot assumes the
active role when the base is powered up.
2. Connect a coaxial cable to each RBC.
3. Plug the power supplies into the designated slots. Be certain the
module is fully seated.
4. After the power supply is inserted, attach the power and ground wires
as shown in Figure 1-8.
