8.3 Troubleshooting the SBx3112 (Diagnostics)
8.3.1 Troubleshooting Overview
When troubleshooting, an out-of service system card is assumed to have been provisioned and providing ser-
vice when a problem occurred, and that replacement may be required. To replace a card, first disable it, then
replace it and enable it. The system will reload the software and configuration data that was previously provi-
sioned for the card. No reprovisioning is required.
8.3.2 Card Diagnostics
The system provides the user with manual card diagnostics using the DIAGNOSE command. The DIAGNOSE
command allows the user to execute tests on card slots. It runs a series of diagnostic tests on the specified card
or list of cards.
Out-of-service diagnostics are the only diagnostics supported. The Line Card must be in the administratively
DOWN state for the diagnostics to run (DISABLE CARD). Note that diagnostics are executed each time a ser-
vice module, network module, or inactive CFC card is enabled.
For the control module, the diagnostics are not run immediately, but are instead scheduled to run during the
next restart of the control module. Since diagnostics tend to be destructive to configuration data, they cannot
be executed on the control module while the system is in service. Therefore, diagnostics are scheduled and are
executed during the next system restart. The restart is requested using the RESTART CARD command.
The
DIAGNOSE CARD
command runs a series of diagnostic tests on the specified card or list of cards. Cur-
rently, out-of-service diagnostics are the only diagnostics supported. (The ALL parameter is not currently sup-
ported.)
For the CFC card, for simplex systems, in order to diagnose the CFC card, the user executes the DIAGNOSE
CARD command with the OUTOFSERVICE option. The user then executes a restart of the card using the
RESTART CARD command. During the enabling sequence for the CFC, diagnostics are executed.
Diagnosing the CFC card should be performed during low traffic periods.
Note:
For a duplex configuration, the inactive CFC card can be disabled, diagnosed, and enabled. However, the active
CFC card must be diagnosed in the same manner as a system card in the simplex configuration.
8.3.3 Interface Diagnostics
The DIAGNOSE INTERFACE command is not supported on the XE4 and GE24 type cards.
