On the test, I will update iLO4 with firmware 1.13 (Nov 08 2012) on the HP ProLiant DL380p G8 server to the latest version 2.50 (Sep 23 2016) at the time of this writing.
And so, download the firmware from the official site http://www.hpe.com/support/iLO4, choosing, for example, the Windows Server operating system, as some do not display the firmware tab “Firmware”.
I also saved it for you in a zip archive here https://drive.google.com/open?id=1mjfHLWPI-BEUT_Bg792c_2a_iJSfVfaV
We will unpack the downloaded archive, it should contain the firmware file with the extension *.bin, this is exactly the firmware.
Connect the cable to the iLO port, open the iLO web interface in Internet Explorer or Edge, enter the username and password (they are usually written on a sticker on the front panel of the server), open the “Administration ” tab on the left, select “iLO Firmware “, click “Browse …” and point to the firmware file, click “Upload” and wait for the update process to complete.
After a successful update, iLO will automatically restart, it will not affect the server, it will work continuously.
We’ll refresh the page, you may have to clear your browser’s cache and we can enter the updated iLO.
Watch the video as I updated iLO3 (the update process is almost the same):
