DIAGNOSTICS
The IPT firmware contains diagnostic routines that can be
invoked during module power-up. These routines verify the
proper operation of the modules components and circuitry.
Putting the IPT module in the diagnostic mode allows the mod-
ule to perform a variety of diagnostic tests but suspends nor-
mal operation. Therefore, use it during installation to check
module integrity, when the system is down, or transfer control
to a backup IPT module. The information that follows describes
how to use the diagnostic routines and gives a brief description
of each test routine.
Overview
Select the required diagnostic routine using the IPT
dipswitches. Diagnostic test results display on the IPT front
panel LEDs. Both group and individual tests can be executed.
The typical procedure is to select a diagnostic to execute, set
the module dipswitches accordingly, reset the module, and
observe the results on the faceplate LEDs. If the halt on error
feature is disabled, the selected test runs repeatedly until the
IPT module is reset and another test is selected. If halt on error
feature is enabled, the test stops and the LEDs display the
failure.
