Select “iDRAC Settings” and then “Network”.
Follow screenshot for configuration. Enter your own IP address.
Click “Back” and scroll down to enter “User Configuration”.
Set a user name and password.
Click “Back” and “Finish” twice to exit configuration and restart the server.
On a workstation in the network, open a browser and type the IP you entered for the IPv4 settings.
Type the user name and password as set in the previous step.
Update the BIOS
Go to “Maintenance” → “System Update” and browse for the BIOS file you downloaded.
Check the box and click “Install and Reboot”.
This will take some time.
Setting Fan Speed
If updating the BIOS wasn’t enough, you should try increasing fan speed.
Go to “Configuration” → “System Settings” → “Hardware Settings” and set as seen in the following screenshot.
Reset to Default
If Updating the BIOS and Settings Fan speed failed, try to reset the BIOS to default. To do so, enter the BIOS settings and click “Default”. After reset, reconfigure the BIOS according to the Manual.
