8900NET (Net Card) — Instruction Manual 29
Status Monitoring and Reporting
The following warning and fault conditions on a media module will trigger
a voltage level signal on the Module Health Bus line:
• Internal module state (and state of submodule or options enabled)
including configuration errors (warning) and internal faults.
• Signal input states including monitored signal not present or invalid
(warning).
• Reference input states including locked, not locked/invalid (warning).
• Signal output states with reporting functionality (reference output).
For 8900TFN and GeckoFlex 8900FFN frames with an 8900NET module,
you may determine what is causing the warning condition on the module
by first viewing the Frame Status web page (see
Frame Status Page on
page 34 ). The status of each module will be reported by color. If a module
is shown in yellow (Warning) or red (Fault), click on the module in the
frame graphic to link to the module Status web page where warning and
fault information will be reported for the that module.
When three or more modules are indicating a warning condition, this may
be reported to the 8900NET module as a Fault condition. This will be
reported on the Frame Status web page (
Figure 15 on page 36 ). This status
reporting can be enabled or disabled using the Internal Healthbus control on
the Frame Alarm Reporting web page ( Frame Alarm Reporting Web Page on
page 42 ). Disabling this reporting does not disable the actual Module
Health Bus reporting to the Frame Alarm, only status reporting to the
Frame Status web page.
The Module Health Bus may be completely disabled by:
• Setting DIP switch S1, segment 5 to Disabled ( Table 1 on page 12 ), or
• (8900NET module) Unchecking the Module Health Reporting selection
on the Frame Reporting web page (
page 42 ) or the LED Reporting web
page ( page 48 ).
