![]() ![]() The systems that didn't have any issue are all the same PN & fw. 1 : 1 ipmitool -I lanplus -H yourIdracIp -U root -P yourIdracPw raw 0x30 0x30 0x02 0xff 0x01 The last value is a hexadecimal value for the RPM in percent. ![]() This seems to be caused by two factors (1) CPU Fan 1 (of 5 total) runs at 12,600 rpm while the others run at 3600 and (2) The 2 power supply fans seem to always be at maximum. First, activate manual fan control: 1 ipmitool -I lanplus -H yourIdracIp -U root -P yourIdracPw raw 0x30 0x30 0x01 0x00 Then reduce the fan’s RPM value to e.g. However once it's stressed or receives lots of network traffic the fans slow down considerably. One is fine but the second one displays bizarre behaviour: If there's minimal load or network activity the fans spin at full speed. Is this likely just buggy firmware, or is it indicative an actual problem? The 495W PSUs are PN 0N24MJA01 running fw version 07.25.7D, and the 750W is 05NF18A01 running 07.2B.7D. In my opinion, my servers (idling with Windows Server 2008R2 and no applications yet) seem to run in the 60 to 80 dBA range. 2 A few days ago we got two new PowerEdge R220 servers. On one of them I tried just pulling the plug, but it didn't clear until I pulled the PSU itself. ![]() Go to Overview > Server > Virtual Console. From the iDRAC9 Configuration menu, select Virtual Console. I pulled the plug from the PSU, then pulled the unit from the server, reinserted it, and plugged it back in. From the iDRAC9 Dashboard (home page), click Launch Virtual Console. I checked the systems, the fans were all running. When I plugged it back in, all the power supplies came back on, however 5 of the systems (4 x 495W, and 1 x 750W) reported fan failure on PS1 (PSU0037). I wanted to see what the UPS thought its runtime would be in the event of a power failure, so I unplugged the PDU from wall power. The servers are configured for PS redundancy, and the ones on wall power were the active PSUs. All have dual power supplies (most 495W with a couple 750W), with one set connected to a PDU on wall power, and the second set on a PDU connected to a UPS. ![]()
