the database by entering the
display bts csmgen command and correct as required using the edit
csm csmgen refsrc command.
* IMPORTANT
If any of the above areas fail, verify:
– If LED is RED, verify that HSO had been powered up for at least 5 minutes. After oscillator
temperature is stable, LED should go GREEN Wait for this to occur before continuing !
– If “timed out” is displayed in the Last Phase column, suspect the HSO output buffer or oscillator
is defective
– Verify the HSO is FULLY SEATED and LOCKED to prevent any possible card warpage
