Re: Meaning of the error message SYS-4-P2_WARN: 1/Astro(module_n

3) If the module number and Astro reference in respect to the error message is alternating modules and Astros, then the error message could be a different type of hardware failure on the Supervisor. Generally, an this type of failure is accompanied by both the Astro Timeout Error Message and BlockTXQueue and
