[c-nsp] Voltage outside of nominal range

[szilard csordas]

Thank you for the information.
Yesterday morning I saw this in the log:


%SPA-2-VOLT_CRITICAL: SPA-2X1GE[2/0] voltage outside of nominal range.
Nominal (1500mV), value(1604mV)

%SPA-0-VOLT_SHUTDOWN: SPA-2X1GE[2/0] voltage out of operating range.
Nominal (1500mV), value (1605mV). The SPA has been shut down.


The hole Gi2/0 interface dissapeared. After the SPA reset (hw-module
subslot 2/0 reload) the line was working for 5 minutes and after that
it shut down by itself. But  when we switched off the power from the
module and switched it on afterwards, since then it has been working.
:)    (no modul added or removed)


sh hw-module subslot 2/0 sensors
SPA-2X1GE[2/0] nominal: 1.500V, reading: 1.524V (the value doesn't increasing).

rgs,
