AHD1 circuit pack or the fans that is preventing the fans from
operating at high speed. Replace the AHD1 circuit pack and/or the
fans. If this succeeds in getting the fans to run at high speed, wait
five minutes to give the cabinet time to cool down and, rerun the
test. If the problem persists, go to step 5.

circuit pack, or the EPN MAINT (Maintenance) circuit pack is
incorrectly reporting this condition. Look for and resolve all errors
on these maintenance objects first, then rerun the test. If the test

follows. Any on of the items could be restricting or redirecting the flow
of air within the cabinet.
a. Check both filters. If a filter is dirty or clogged it should be cleaned
or replaced. The filters can either be washed with soap and water
or vacuumed.
b. Make sure there is nothing (other than circuit packs) in the carrier
slots that could be restricting the air flow.
c. Make sure there are no missing (blank) circuit pack or carrier
faceplates. Install and/or replace them as necessary.
d. Make sure the cabinet door is properly closed. The door must be
closed for the fans to be able to properly cool the cabinet. Wait five
minutes to give the fans a chance to cool the cabinet. Rerun the
test. If the tests still fails, proceed to Step 6.
