Please follow the below steps
- Download and extract the zip file, it has a "cpldtest" binary
- Upload the cpldtest file to the problematic unit (/var/tmp directory)
- Login to the unit, and execute the binary as below (this will basically read the fan speed in hex)
cd /var/tmp
chmod a+x cpldtest
sudo ./cpldtest -a 0x81 -r
<for example, below, if the value turns out to be 0 it would mean that the fans are not functional>
[admin@versa-flexvnf: ~] $ sudo ./cpldtest -a 0x81 -r
Read CPLD register 0x81: 0x65
[admin@versa-flexvnf: ~] $
