C)
Recommended action
1. Verify that the local ambient environment temperature is
within the acceptable range.
2. Check the installation for any airflow restrictions at either
the front or back of the enclosure. A minimum gap of
25 mm (1") at the front and 50 mm (2") at the rear is
recommended.
3. Check for restrictions due to dust build-up. Clean as
appropriate.
4. Check for excessive re-circulation of heated air from rear
to front. Use of the enclosure in a fully enclosed rack is not
recommended.
5. If possible, shut down the enclosure and investigate the
problem before continuing.
