Installation
Installation of the Communication Cables
Install the INP communication interconnecting cable assemblies as follows:
1.
Connect the board connector of the appropriate interface cable (sometimes called "internal"
cable) to connector 11 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 subsystem.
NOTE
The use of the terms "internal" and "external" in the nomenclature of the
INP communication interconnecting cable assemblies was established when
a different model of the INP was developed for use in another series of the
HP 3000 family of computer systems. In that application, the internal
cable was installed inside of the computer cabinet to connect the INP to the
inside of a junction panel. The external cable was then joined to the
internal cable by attaching the external cable to the outside of the junction
panel. Although that previous usage of the terms "internal" and "external"
occasionally still prevails, both segments of the cables used with the
HP 30244M INP are installed outside of the HP 3000/37 computer
cabinet. In an effort to reduce any confusion that might be caused by this
nomenclature, the newer cables are being called "interface" (instead of
"internal") and "extender
ll
,
(instead of "external
ll
).
2.
Route the interface cable (which you already attached to the INP PCA in step
1)
to the point
where it will mate with the extender cable.
3.
Attach the extender cable to the inte ace cable. (On the HP 3000/37, the two cables are
joined with their connectors outside of the omputer cabinet.)
4.
If an INP-to-modem connection is being m
e, route the extender segment of the data
communication cable assembly directly to the 10
~
modem and attach the connector to the
modem.
'\
5.
If a direct INP-to-INP connection is being made (bypassing all modems), route the interconnect
extender cable (one of the HP 30224L-series of cables listed in Table
1-1)
directly to the other
computer in your data communications network. The other end of the interconnect extender
cable connects to another INP-to-INP direct-connect interface (or internal) cable for the
remote computer.
6.
If a direct INP-to-SSLC connection is being made (from your local computer with its INP to a
remote computer with an SSLC), route the INP-to-SSLC direct-connect extender cable (part
no.
30225-60007) directly to the remote computer. Connect the other end of the
direct-connect extender cable to the remote computer's modem interconnecting cable
(completely bypassing all modems).
