Configuration Restriction - HP AdvanceNet 30244M Installation And Service Manual

Installation
7. Record the location of the INP PCA in the Configuration section of the
System Support Log.
8. Reinstall the back panel.
NOTE
Reconnect the fan if it was unplugged in step 5.
9. Connect the INP to the Peripheral Interface Channel (PIC) by attaching the HP-IB Cable
(product no. HP 92220R) to the INP PCA connector J3 and to the PIC.
NOTE
Multiple HP-IB Cable connections to the same PIC must be accomplished in
accordance with the IIConfiguration Restriction ll paragraph below.
10 Reconnect all of the cables removed in step 4.
11 Reconnect the line-power cord to restore AC power.
Configuration Restriction
Although multiple INPs (up to three) can share the same Peripheral Interface Channel (PIC) with one
high-speed device, the devices
cannot
all have their HP-IB Cables connected directly to the same PIC
connector (sometimes called a II s tar" configuration).
A maximum of two HP-IB Cables can be physically coupled to anyone PIC or INP PCA board.
Therefore, the recommended way of cabling multiple INPs to the same PIC is in the IIdaisychain
ll
configuration. IIDaisychaining
ll
is accomplished by attaching the HP-IB Cable of the first INP from the
INP to the PIC. Then, the HP-IB Cable from the second INP is coupled to the first INP. Likewise, if
there is a third INP, the HP-IB Cable from the third INP is coupled to the connector on the second INP.
