System Clocking Configuration window 82
Models 2616RC, 3096RC & 3196RC Admin Reference Guide 6 • System Clocking
• Secondary System Fail—The clock signal provided by the blade in the cPCI chassis with its clocking mode
defined as Secondary has failed.
• Fallback Indication—The T-DAC has switched its clocking source to the fallback reference.
Enable/Disable Fallback System
This parameter defines the T-DAC’s clocking fallback mechanism as enabled or disabled. By default, the clock-
ing fallback mechanism is enabled at the factory before the T-DAC is shipped. To deactivate the T-DAC’s fall-
back system you must disable it. When disabled, the T-DAC will not use the fallback reference clocking source,
even if the primary reference becomes unavailable. To define the Enable/Disable Fallback System parameter,
select one of the following values from the drop-down box.
• disable(0)
• enable(1)
Once you have defined the desired value for the Enable/Disable Fallback System parameter, you must click the
adjacent Submit Query button to save your selection into volatile DRAM.
Enable/Disable Clock Auto Recover System
This parameter defines the T-DAC’s clocking auto recover mechanism as enabled or disabled.The clock auto
recover feature, when enabled, switches the T-DACS from fallback reference clock to primary reference clock
(when this becomes available again). By default, the clocking auto recover mechanism is enabled at the factory
before the T-DAC is shipped. To deactivate the T-DAC’s auto recover system you must disable it. When dis-
abled, the T-DAC will not switch to primary reference clocking source, even if the primary reference becomes
available. To define the Enable/Disable Auto Recover System parameter, select one of the following values from
the drop-down box.
• disable(0)
• enable(1)
Once you have defined the desired value for the Enable/Disable Fallback System parameter, you must click the
adjacent Submit Query button to save your selection into volatile DRAM.
Saving your work
Once you have defined your desired values for the system clocking parameters, you must click the Record
Current Configuration button on the HOME window to save your settings into non-volatile memory (see
section “Record Current Configuration (storeConfig(1))” on page 42 for details).
