What is hm2PSUUnitFanCount?

This value, from 0 to 2, reports the number of cooling fans built into a power supply slot module unit. Admins use it to know how many fans to expect functioning normally on that PSU unit when checking for cooling issues. A PSU unit reporting hm2PSUUnitFanCount as 2 tells the admin to look for two spinning fans if that unit is later reported as overheating.
