R2.x.x or earlier. The introduction of the new Fan Tray (P/N 5394406) fails system level diagnostic "GFI

The "GFI Fan Test" diagnostic checks for basic fan movement at two set points. The diagnostic checks

fan rotation by applying two different control voltage Duty Cycles to the fan tray. The current test

implementation sets restrictive limits on the rotation RPM. These rotation limits need to be widened

(become less restrictive) which will allow for fan and supplier variation.

This Section will instruct how review the test results data and assess if the fan is bad. This diagnostic

failure does not affect normal operation, it will only occur when running diagnostics.
