Over Temperature LED is Illuminated
The Over Temperature LED illuminates to indicate that the switch logic circuitry is
overheating. If the Over Temperature LED illuminates, do the following:
1.
Inspect the chassis fan. Is the intake opening clear? Is the fan operating and
producing air flow?
2.
Consider the ambient air temperature near the switch and clearance around
the switch. Make necessary corrections. If the condition remains, contact
your authorized maintenance provider.
