5. If the fans are running at high speed, check the items on following list. 

Any one of these could be restricting or redirecting the cabinet’s air 
flow.

●

Check filter; if the filter is dirty or clogged it should be cleaned or 
replaced. The filter can either be washed with soap and water or 
vacuumed.

●

Verify that nothing other than circuit packs in the carrier slots that 
could be restricting air flow.

●

Verify that no circuit-pack blanks or carrier faceplates are missing. 
Install and/or replace them as necessary.

●

Be sure the cabinet’s doors are properly closed. The doors must be 
closed to enable the fans to properly cool the cabinet. Wait 5 
minutes to allow the fans to cool the cabinet. Rerun the test. If the 
test still fails, proceed to Step 6.

6. At this point, there should be nothing impeding the air flow, and the 

fans should be running at high speed. Check the temperatures for the 
5- to

 

60

0

-C criteria.

●

If the 5- to

 

60

0

-C criteria exists, a temperature problem exists, and 

the fans (at high speed) should cool down the switch. Wait 5 
minutes, and rerun the test. If the test still fails, the ambient room 
temperature is probably too high, and the room should be cooled.

If not, the fans are defective. Replace the fan assembly, and rerun 
the test. Failures can occur on the Processor circuit pack that is not 
detected by the respective MO, but that cause many, if not every, 
environment test to fail. If many environment tests are failing, the 
suspected circuit pack (depending on the system configuration) 
should be replaced and the test rerun.

There is a problem with the environment of the power system:

1. The power unit for the cabinet may be defective.

a. Verify and, if necessary, replace the power unit.

b. Rerun the test. If the test still fails, escalate.

PASS

The cabinet does not have a power or fan problem. If a problem is reported, 

troubleshoot by using the previous procedures for the FAIL cases.
