locating main and redundancy fan on a SYTF2

[Anonymous user]

Hi I have a SYTF2 operating, and I'm trying to find if the main fan is OK.

The APc user manual estates the following:
"The redundant fan will not operate unless the internal
temperature of the unit becomes 100 °F or failure of
the main cooling fan."
But The manual doesn't point which fan (left or right) is the main, and the redundancy. So I can't know if the fan that is operating of my SYTF2 is the main or the redundancy one.

Thanks

they both are identical. the transformer is designed to just use one fan at a time. i dont think they are labeled as main or redundant unfortunately and neither are user replaceable. if you just have one spinning, then that is fine. i'd keep an eye out for if you ever see that neither fan is spinning to be honest with you.
