Description
management module increases fan speed to increase cooling
and reduce the temperature.
At least one temperature sensor is detecting a temperature
outside of the acceptable operating range. In this case an
upper critical (UC) temperature. The management module
increases fan speed to the maximum level. This also
indicates possible problems with the cooling system and
could mean that the ambient temperature is too high. Also
causes a major or critical (CR) alarm.
At least one temperature sensor is detecting a temperature
outside of the allowed operating range. In this case an upper
non-recoverable (UNR) temperature. The management
module increases fan speed to the maximum level. The
temperature is high enough to potentially cause physical
damage. Also causes a critical or non-recoverable (NR)
alarm.
Normal operation.
Chassis 12V disabled. This means that the administrator has
entered commands into the management module CLI to
power off the PSU main 12V outputs. All fans, FIM and FPM
modules are completely powered off but the management
module is still running.
Chassis 12V enabled but not OK. This means the
management module has enabled the main 12V outputs for
all chassis components, but the power OK (PWOK) signal of
at least one PSU has not been sent. When a PSU is powering
up, it would be normal for this LED to be red for a second
(before PSU outputs are stabilized), but if LED remains red, it
indicates a problem (such as a failed PSU). Management
module or FIM or FPM module voltage sensors would most
likely also trigger alarms if this happens since the PSUs may
not be delivering enough power.
Fan tachometer sensors disabled. This could happen if the
administrator disabled them from the management module
CLI.
The fan tray is operating normally.
The fan tray is not working. Chassis cooling may be sufficient
but redundancy is lost and the fan tray that is not working
should be replaced.
A fan tachometer sensor in this fan tray has registered an
alert because a critical or non-recoverable (NR) threshold has
been crossed.
