Chassis Over-Temperature Detection

i. If a switch reaches an over-temperature condition, it generates a
chassis-module Warning message in the Event Log and in any
optionally configured debug destinations (console session and
SyslogD servers). If the switch later returns to its acceptable
temperature range, it signals this event with a chassis module
Information message to the same destinations. These messages
include the number of times the switch has detected the events
since the last reboot. For example, suppose that you notice the
following three messages at the end of the current Event Log
message listing:
The above messages indicate that the switch detected the following chassis
conditions since the last reboot:
1. 16
2. An over-temperature condition occurred on August 17, 2003 at 11:28:05,
meaning the switch was operating above its acceptable, internal temper­
ature range. The Failure value of "1" indicates this is the first over-
temperature condition to occur since the last reboot.
3. The switch returned to its acceptable temperature range at 11:33:23 on
the same day. (To determine this temperature range, refer to the Instal­
lation and Getting Started Guide shipped with the switch.)
4. Another over-temperature condition occurred on August 17th at 12:03:18
and the switch is currently operating in this condition. The Failure value
of "2" indicates this is the second over-temperature condition to occur
since the last reboot.
If an over-temperature condition occurs, continued operation can result in
damage to the device.
Check the event log for fan failure warnings. If the switch has experienced
a fan failure, remove power from the switch and contact your ProCurve
service and support representative.
