6. Insert the output driver cards (090-55581-01) where desired in the
slots on the front side of the expansion shelf. Note that when a driver
card is installed into a location that has corresponding connector
modules attached at the back of the shelf, there should be confir-
mation that those modules are present on the output driver card
LEDs.
7. Assuming that all prior steps have been successfully completed, the
output driver cards should become initialized by the master shelf.
The basic sequence to expect for each driver card is:
a. The front-panel LEDs will blink as the card first powers up.
b. The Power and Alarm LEDs will remain lit, as well as LEDs iden-
tifying any connector modules that are attached at the back of
the shelf. The alarm LED is lit to indicate that the card has not
yet been initialized (i.e., received configuration information from
the master shelf).
c. As the card becomes recognized by the master shelf, it will re-
ceive communication causing it to become initialized. Prior to
initialization, an output card never generates any output, it
waits to be told what to do. The initialization configures the out-
put card according to whatever user configuration has been es-
tablished for the slot into which the card is inserted. This
consists of such settings as whether or not the outputs are en-
abled and what type of framing is desired.
As each card becomes initialized, its Alarm LED will
extinguish. At this point the card is configured per desired
setup and is ready to be further configured if desired. If
outputs have been enabled for that card, they should be active.
Note that for a fully loaded shelf, the initialization process
could take several minutes in total. If only a single output card
is being inserted, the time will be much less than that.
8. Connect THC (or terminal program) to confirm (via RTRV-NETYPE-
ALL command) that the shelf configuration is now as expected. If
connected with TimeScan THC, this can be checked by bringing up
a communication form (select menu "Mode->Command Response")
and sending the RTRV-NETYPE-ALL query (select menu
"TL1Commands->RTRV-NETYPE-ALL" or F2). Here is a typical re-
