The show hw-module subslot all oir command
displays an "Environmental limits exceeded" reason
code.
The show hw-module subslot sensors command
displays the actual values for the temperature and
voltage on the Cisco WebEx Node SPA, as shown in
the following example:

The following is an example of an
error message due to excessive
temperature:
*Jan 27 17:46:22.285:
%SPA-0-TEMP_SHUTDOWN: SIP1/1:

possible that the logging buffer

found, enter the show logging |
include VOLT_SHUTDOWN
command to find a voltage shutdown
error message.
If an error messages indicates a
voltage problem, then the SIP could
be providing an unstable voltage to
the SPA, or there might be a hardware
problem on the Cisco WebEx Node
SPA itself.
Try installing the SPA into another
SIP and see if the problem continues.
If the problem still occurs, then there
is a voltage problem on the Cisco
WebEx Node SPA.
