Could be a hardware issue, is the Server tested and certified for use with ESXi, see the HCL to check this.<br />
<br />
Check the <b>VMware Hardware Compatability Lists </b>HCL <a href="http://www.vmware.com/go/hcl" rel="ugc nofollow">here</a><br />
<br />
The VMware Hardware Compatibility List is the detailed lists showing actual vendor devices that are either physically tested or are similar to the devices tested by VMware or VMware partners. Items on the list are tested with VMware products and are known to operate correctly.Devices which are not on the list may function, but will not be supported by VMware. <br />

<br />
So you have no yellow over black screen with information on how to connect to the ESXi server ?<br />
<br />
How did you enable SSH ?<br />
<br />
It's possible you have a hardware issue, or your server is not compatible.<br />
<br />
If you select ALT-F12, do you see any warnings or messages.<br />
<br />
Have you tried restarting, and also re-installation, of maybe ESXi 5.5 ?<br />
<br />
Some of my EE Articles may assist you<br />

Hello Thank you for answering. I initially receive the black and yellow login screen, but if I don't login after a minute the blank &quot;mem&quot; screen appears, but if I hit F2 the regular login screen appears and I can log in fine. &nbsp; I did check the VMware Compatibility list and my machine is on there. I have other ESXi 6.0 servers installed on the same PC make and model and they are working fine. &nbsp;I checked the memory on my machine because of the &quot;mem&quot; showing up on the blank screen but ESXi is showing all memory is good. I have reinstalled ESXi 6.0 but not 5.5. Should I do that and then upgrade to 6.0?

I have installed ESXi 6.0 on my machine and can't connect to using from a client machine using . I am trying to install vsphere client software. The log in screen changes to a blank black screen with &quot;mem&quot; located on the upper left corner of the screen. But when I hit F2 the log in screen returns. I checked and I have SSH enabled. I have checked all network connections and they work, but I can't ping to it or connect to it. Does this mean this is a hardware issue?

VMWare ESXi 6.0

VMware, a software company founded in 1998,  was one of the first commercially successful companies to offer x86 virtualization. The storage company EMC purchased VMware in 1994. Dell Technologies acquired EMC in 2016. VMware’s parent company is now Dell Technologies.

VMware has many software products that run on desktops, Microsoft Windows, Linux, and macOS, which allows the virtualizing of the x86 architecture.  Its enterprise software hypervisor for servers, VMware vSphere Hypervisor (ESXi), is a bare-metal hypervisor that runs directly on the server hardware and does not require an additional underlying operating system.
