I have an E5071B ENA RF Network Analyzer.
The system doesn't boot up. I took a picture of the display to show the error messages.
I thought the HDD has some issues so I replaced the harddrive with an empty harddrive, The error messages changed and I only get the following error messages:
PXE-E61: Media test failure, check cable.
PXE-M0F: Exiting Intel Boot Agent.
Operating system not found
I took picture of both errors
Yes, that looks like the hard drive failed. The replacement blank drive doesn't find an operating system. You can return that for repair, or check with the support portal to see if there is a replacement hard drive available.
