4.6.2.1 Installing Host Port Cables for HSJ Array Controllers
Preconfigured HSJ array controller subsystems come with the internal host port
cable preinstalled. When adding a second controller to a nonredundant (single)
controller configuration, do the following:
• Position and route the new internal CI host port cable using the same path as
the host port cable for the first controller.
• Connect the internal CI cable to the front of the controller, and tighten the
captive screws on the internal CI cable where it attaches to the controller’s
front bezel using a flat-head screwdriver.
• Connect four external (blue) CI cables to the exiting end of the internal CI
host port cable connector and then route them to the star coupler.
CAUTION
Always connect the four external (blue) CI cables to the internal CI host
port cable connector first, then connect it to the star coupler second.
Never leave unterminated paths on the star coupler. Never leave cables,
terminated or not, attached at the star coupler and disconnected at the
internal CI cable connector. This minimizes adverse effects on the cluster
and prevents a short circuit between the two ground references.
Figure 4–9 shows the physical attributes of an internal CI host port cable.
The connection of the transmit and receive external (blue) CI cables to the
PATH A connections of the internal CI cable connector also are shown.
Note
The four CI cable connections located on the exiting end of each internal
CI host port cable have rubber shipping caps on each connection. Remove
the rubber shipping caps before connecting the external (blue) CI cables.
Keep these caps with the cabinet for later use. Follow the CI cable
handling guidelines in Section 4.3.3.1.
• Remove any terminators from the star coupler connections.
• Connect the external CI cable connectors to the star coupler one at a time, in
the following order (refer to Figure 4–9):
RXB
TXB

• Install any tie wraps as necessary to hold the internal CI host port cable in
place.
• If you are not going to perform any other operations inside the cabinet, close
and lock the cabinet doors (this assumes your initial controller parameters
are set).
