Figure 3-5. SDN Non-Instrument Malfunction
•
If the problem affects only one instrument or all the instruments on
the branch, go to STEP #5.
•
If the problem does not affect all instruments on the branch, it can
be concluded that the ACC and cabling running up to, but not
including the last “good” instrument, are functioning properly. Go to
STEP #5.
The problem is located in one of the following places:
a. SDN Interface PC Board (drivers, receivers and relays and other
circuitry were not tested in instrument’s self-test routine).
b. ACC (components which are branch-specific)
c. Cables/Connectors (LDC, wall box, SDC, connection to ACC)
In order to verify which part of the branch is faulty, it is now necessary to
swap the branch with a known good branch:
At ACC, disconnect RJ45 connectors and jump wires to an unused branch.
Caution
CAUTION — Ability to view swapped monitor/terminal:
•
If the “unused branch” is not in the same Unit (e.g., same ICU) as the
former branch, then it cannot be viewed in OVERVIEW mode.
Unused bedside branches will be in Care Unit 1 if default values
were programmed in the IC(s) at installation.
•
If the “unused branch” is outside the tuning range of the IC, then it
cannot be viewed at that IC.
