2.If clock settings are correct, skip remaining steps.

3.If primary clock setting is incorrect, set clock1 source with the following command: set clock1 <setting>

There are three different settings, which are defined as follows:

Setting	Definition
bits	Select external or BITS source on Timing In connector
ds1 <n>	Select clock recovered from DS1 number n
internal	Select internal oscillator

4.If secondary clock setting is incorrect, set clock2 source with the following command: set clock2 <setting>

Example: set clock2 ds1 5

Choose setting from list in previous step.
