Installation
2-7. Installation of the Communication Cables
Install the INP commun ica tion interconnecting cable assembl ies as
follows:
a. Connect the hood connector of the appropriate internal cable
to connectors Jl and J2 of the INP PCA board. Refer to table
1-1 for a list of the available INp-to-modem cables, INP-
to-INP direct-connect cables, and INP-to-SSLC direct-connect
cables. Also refer to figure 1-1 as an aid in visualizing
the relationship of the hardware components of the INP sub-
system.
b. Route the internal cable (which you already attached to the
INP PCA in step a) to the point where it will mate with the
exte rnal cable.
On the HP 3000 Series 30, route the internal cable down-
ward, through a cable clamp, and out of the cabinet with
the other computer cabling (as shown in figure 2-4) •
On the HP 3000 Series 33, route the internal cable in the
cable channel along the lower front edge of the inside of
the card cage. Attach the cable connector to the inside of
the bulkhead connection panel on the end of the card cage.
(See figure 2-5.)
c. Attach the external cable to the internal cable.
On the HP 3000 Ser ies 30, the two cab les are joined with
their connectors outside of the computer cabinet.
On the HP 3000 Series 33, attach the external cable to the
outside of the card cage bulkhead connection panel so that
it connects with the internal cable installed in step b.
d. If an INp-to-modem connection is being made, route the
external segment of the data communication cable assembly
directly to the local modern and attach the connector to the
modem.
e. If a direct INP-to-INP connection is being made (bypassing
all modems), route the external interconnect cable (one of
the HP 30224L-series of cables listed in table 1-1) directly
to the other computer in your data communications system.
The other end of the external interconnect cable connects to
anoth~r
INP-to-INP direct-connect cable for the remote
compute r.
