Look carefully at the status display and OK indicator when powering
up the module. These indicators provide meaningful information on
proper module operation.
1. Apply power to the chassis – the OK indicator should not light.
2. The module runs a power on self test (POST). During this test,
the status displays 0000 through 8888.
3. If the OK indicator is red, and the display shows POST-RSET,
then POST has failed.
a. Press the reset pushbutton to reset.
The module reruns the POST program. If POST-RPLC
appears on the status display again, POST has failed again.
b. Replace the module.
4. If:
a. the OK indicator begins to blink green, and
b. the series/revision level of the module is displayed in the
status window (e.g. A/A, A/B, etc.), and
c. the channel A and B indicators blink alternately, the module
has passed POST.
If the indications are neither of those indicated in 3 or 4, refer to
chapter 5, “Troubleshooting.”
5. The module status displays INIT-A#nn (where nn is the node
number of module).
6. The channel indicators indicate network condition as shown in
the indicator table in chapter 5.
7. Then the display shows IDLE-A#nn (where nn is the node
number of module), indicating a successful configuration by the
ControlNet Configuration Manager.
