I got a Nexus 5010 from our spare parts department. \u00a0When I booted it up, lo and behold, it thought it was a UCS Fabric Interconnect 6020!<\/p>\n
As most people know the 6120XP is the same hardware as the Nexus 5010. \u00a0Only difference is that its spray painted green. \u00a0Well this particular model I got was gray and said it was a Nexus 5010. \u00a0So I was bound and determined to get it back. \u00a0I got pretty close, and wanted to write down the steps I took.<\/p>\n
I’m sad to say, however, that I didn’t get it to work all the way.<\/p>\n
Here’s what I did:<\/p>\n
Step 1. Get TFTP server setup (This explains how to do it for a MacBook Pro)<\/strong> sudo launchctl load -F \/System\/Library\/LaunchDaemons\/tftp.plist<\/p><\/blockquote>\n (Turning it off is done with:<\/p>\n sudo launchctl unload -F \/System\/Library\/LaunchDaemons\/tftp.plist<\/p><\/blockquote>\n ) sudo launchctl list | grep tftp,<\/p><\/blockquote>\n if you see output its running, if not, its not)<\/p>\n From there you need to put the files you need into the \/private\/tftpboot\/<\/p>\n I went to Cisco’s support page and easily found two files: I had to copy them with sudo since you’re going into a privileged directory.<\/p>\n You should test your tftp server to make sure it works. No use yelling at the Nexus 5000 for telling you it can’t access the file.<\/p>\n From the command prompt on the mac:<\/p>\n cd ~\/Desktop If that works, you are in business.<\/p>\n Step 2. Load the Nexus 5000 (that thinks its a 6100) into the loader prompt.<\/strong><\/p>\n When the machine started booting, I had to do<\/p>\n Ctrl+Shift+R<\/p><\/blockquote>\n right as it was loading the UCS kickstart file. Doing this got me to a prompt.<\/p>\n From here, we don’t have a lot of options. But all we need to do is set the mgmt0 interface and kickstart from our Nexus image that we have on tftp. Here’s how we set that:<\/p>\n loader> set ip 192.168.1.99 255.255.255.0<\/p>\n Then it confirmed that this was good. Now, to load up the kickstart file:<\/p>\n loader> boot tftp:\/\/192.168.1.234\/private\/tftpboot\/n5000-u9-kickstart.5.2.1.N1.5.bin the system then boots up. Does some image verification and loads into a boot prompt:<\/p>\n Cisco Nexus Operating System (NX-OS) Software Step 3: Copy files and continue booting<\/strong><\/p>\n Now we just need to get the files on the device.<\/p>\n switch(boot)# con t At this point I went downstairs and had some chips to eat. I got back and had to wait like 15-20 min for it to copy. Shesh! Finally, when I was about to cancel it, I saw:<\/p>\n TFTP get operation was successful Now we need to get the kickstart file:<\/p>\n switch(boot)# copy tftp:\/\/192.168.1.234\/n5000-uk9-kickstart.5.2.1.N1.5.bin boot flash:<\/p><\/blockquote>\n So I waited some more, this one didn’t take as long.<\/p>\n Then I deleted a bunch of UCS files:<\/p>\n switch(boot)# delete bootflash:ucs-6100-k9-system.4.0.1a.N2.1.0.1036.gbin Then I booted the image:<\/p>\n switch(boot)# load n5000-uk9.5.2.1.N1.5.bin<\/p><\/blockquote>\n This set me to the boot prompt again. So I hit exit:<\/p>\n boot switch(boot)# exit<\/p><\/blockquote>\n It kept rebooting to stored images of UCS manager. So I found this command:<\/p>\n init system check-filesystem<\/p><\/blockquote>\n From here, I repeated the operation of downloading the 2 Nexus images. \u00a0At least now it didn’t boot up into UCS Fabric Interconnect, but I could never get it to go to regular Cisco Nexus 5010. \u00a0It may be that there was something wrong with the hardware. \u00a0It certainly looks a little beat if you look at this hardware. \u00a0If nothing else, I learned a little more about the boot files in the Nexus 5000.<\/p>\n","protected":false},"excerpt":{"rendered":" I got a Nexus 5010 from our spare parts department. \u00a0When I booted it up, lo and behold, it thought it was a UCS Fabric Interconnect 6020!

\nI’m running Mountain Lion OSX. Turns out there is a default tftp server installed with it. Getting it running is pretty easy. Just run:<\/p>\n
