I verified that the log does not show what might be an issue, there are two warning entries, because of a power outage which caused the network connection to drop. Almost immediately, the connection was restablished and an entry in the log confirmed this. Other entries are either informational or minor. When I clicked on the reset status LED button, it does not change the red lights on the main and expansion chassis. Acknowledging the alarm does not change anything either. Perhaps the modules have failed and need replacement, has anyone seen this before? I have noticed increased trouble calls regarding the phone, static on the lines, dropped calls, sets not in service etc. None are service stoppers but annoying and I am at a lose on how to fix it.
