Multiple IPMI SDR entries for FAN

The DL145G2 machine has only 6 fans, but the ipmi sdr list shows that it has double the no of fans, (ie) 12.

Re: Multiple IPMI SDR entries for FAN

Hi,

The fan assemblies on DL140 and DL145's are actually dual fans (back to back) and each connector on the system board or front panel board monitors each dual fan assembly.

So there are 12 fans in total.

Please see attached image which shows the dual fan assembly and positions on the system board and front panel board.

I hope this helps.
