Hello All,
For the 2nd time we have had a CP280 start to show failures in baretail/sysmon
log. We only have a total of 4 CP280's at our site.
Example:
2019-05-20 04:35:17 25CP01 Equip = CHAN_1 SYSMON -00222 CP Power 2 failed
2019-05-20 04:35:17 25CP01 Equip = CHAN_1 SYSMON -00223 CP_Power 2 OK
The failures do not cause the system light to flash green, no * on the CP, but
only show up in the log. The fault occurs and clears within the same second.
And they occurred progressively more often over time (a couple of weeks) Power
supplies and connections all look good. Disconnecting a power connection
causes the exact same error. The first time it occurred we changed the shadow
module but the errors re-occurred. We then replaced the other partner and the
problem went away. Now the problem has shown up again on another CP in another
area. We have replaced the shadow on that one and are waiting to see if the
errors return. When I called them about this on the first occurrence TAC told
me they had seen this before, it was something about an optocoupler inside the
CP and was not a real power failure.
This time the errors say "CP Power 1" instead of 2.
Anyway, just curious if anyone else has experienced this. Could it really bite
us?
Happy Thanksgiving!
