Troubleshooting Cooling Problems
PowerEdge C8000 server enclosure supports chiller-less fresh air cooling that enables the enclosure to operate at room temperature and tolerate temperature spikes up to 45 °C (113 °F). Fresh air cooling controls temperature in the enclosure through fan speed. Outside air is drawn and circulated through the enclosure interior to cool the enclosure and components. You can use IPMI messaging to switch the air flow in the enclosure to fresh air mode or normal operating mode.
To enable fresh air cooling in the enclosure:
1Enter the following command:
ipmitool -I lanplus -P <password> -U <username> -H <BMC IP address> raw <command>
where
-I lanplus is the LAN plus interface that uses the Remote Management Control Protocol+ (RMCP+) protocol to communicate with the BMC over an Ethernet LAN connection
-P <password> is the password for the given user ID
-U <username> is the username associated with the given user ID -H <BMC IP address> is the BMC IP address
<command> is the command for configuring the fresh air mode For example, the command line should have the following format:
ipmitool –I lanplus –P root -U root –H 192.168.70.58 raw 0x30 0x43 0x01 0x01
2Enter the following command:
ipmitool –I lanplus –P root -U root –H 192.168.70.58 raw 0x30 0x43 0x01 0x01
