Other Alarms

BIP

Most of the BaBar and PEP II Alarms are generated by their own
monitoring systems. Our Displays are just mirroring the actual
monitors. If the number or text has gone white, most likely, something
between the two machines is preventing the mirroring.

The PEP II IOC monitors itself differently than the BaBar IOCs. It
gives memory in use, file descriptors in use, and CPU in use
indicators. The memory has been the most problematic. By observation,
the 90% usage level sets off a warning and the 95% level is an
alarm. The consequences of low memory include problems creating
connections between CEN-BIP and the PEP II IOC.

CRY

Most of these channels are not yet defined.

GMS

These alarms are triggered in hardware. The summaries are done by the
CEN-GMS IOC.

CEN

The cooling alarms go off if the highest temperature passes 40 degrees
C. A sequence scans all the temperatures in the rack every 15
seconds. There is no deadband set on this temperature reading. The
temperature reading does not reflect any alarm set for the reading
inside the rack.

The color outlines around each button summarize the highest alarm in
that sub display. The invalid (or disconnect) alarm is highest, then
the alarm, then the warning.

SIAM & VSAM

Thus far, no IOC-definable analog alarms have been set for these
devices. Refer to each system's documentation for more information.
