Troubleshooting Module Type Errors
If a slot is configured to receive a specific card type, and someone installs a different card type or
removes the installed card, an alarm is triggered. Within MRC, alarm signals are distributed to
three separate pages: ‘Module Types’, ‘Module Status’, and ‘System Status’.
In the ‘Module Types’ page, a red dot appears on the ‘View Change Report’ button when the
router’s control card reports an unexpected module change. Click View Change Report, at the
bottom of the page, to view the error message(s) at any time.
This is a sample of the report:
Alarms are also sent through SNMP to the router control system and router alarm ports, which
might be connected to an external alarming circuit.
You can correct an error by:
• Changing the card type assigned to the slot so that it matches the card physically installed in
the slot.
• Removing the installed card and replacing it with a card that matches the card type assigned
to that slot.
How to Change Individual Modules
1 Go to the ‘Module Types’ page. From the Hybrid Routers table at the bottom of the page,
select a control card.
If module error(s) has been detected for this router, the ‘Unexpected Module Change Errors’
window appears. (You can click
Print to print the error list for reference or click Save to save
it to a file.)
2 Scroll to the row for the slot you are modifying. (Only rows for which the ‘Module’ field has a
drop-down menu can be modified. That is, you can modify the card type only for empty
slots.)
3 Click the ‘Module Type’ field and select a card type from the drop-down menu that appears.
4 Repeat steps 1–3 for other slots you want to modify.
