Chassis Over-Temperature Detection
since the last reboot. For example, suppose that you notice the
following three messages at the end of the current Event Log
message listing:
Figure C-1. Chassis Over-Temperature Messaging
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.
CAUTION 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.
■ If there are no fan failures, ensure that the ambient temperature in the
switch’s operating area is not causing the over-temperature condition. If
the condition persists, remove power from the switch until you can find
the cause and apply an effective remedy.
