Multiple Inp Installations - HP 30020B Installation And Service Manual

Installation
c. Press the chrome, spring-loaded RESTART switch on the edge of
the INP PCA board (figure 2-5) to manually initiate the self
test.
d. Watch the self-test light-emitting-diode (LED) indicators
(figure 2-5) as the self-test program goes through its cycle.
Upon completion of the self test (approximately 2 seconds in
duration), the LEDs will stop blinking and will display a
steady pattern. If the two LEDs at each end (0 and 7) are
lighted while all the others are off, the INP is working
properly. If any other pattern of lighted LEDs is being
displayed, the INP is malfunctioning.
e. If a properly functioning INP is indicated, close and lock
the card cage door. The system is now ready for operation.
f. If a malfunctioning INP is indicated, refer to Section V,
Maintenance, for trqubleshooting information.
2-10. MULTIPLE INP INSTALLATIONS
For additional data communication capability, more than one INP
can be installed in the same HP3000 HP-IB Version Computer Sys-
tem. The maximum number of INPs that one HP 3000 Series 33/44
can accomodate is seven. A maximum of three INPs can be ins-
talled in the HP 3000 Series 30/40, and a maximum of 16 INP's
can be installed in the HP 3000 Series 64 (see table 1-3).
After the first INP has been installed, subsequent INPs are in-
stalled by following the same procedures as outlined in the pre-
vious paragraphs in this section. Any available card slot within
the specified range can be used, since the device sequence is
determined by the setting of each INP's HP-IB address switch,
rather than by the card slot it occupies.
When multiple INPs are installed in an HP 3000 33/44, no more
than three INPs can be located in the first card cage (the middle
section of the HP 3000/33 mainframe, as shown in figure 2-3).
The fourth through seventh INPs must be located in the second
card cage.
