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:

Enter 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

Enter the following command:

ipmitool –I lanplus –P root -U root –H 192.168.70.58 raw 0x30 0x43 0x01

0x01
