Jerry,
It can be tricky. It's best to make sure you do this while at 9600 baud on your console. Try using "ctrl + b" a few times after seeing the text "POST is completed"

I have read the Nexus 5000 and I am also having great difficulty getting into the password recovery. Can someone clarify, in the password recovery document when ctrl-b or ctrl-] is referenced, the Nexus is looking for the BREAK signal.
Terminal emulators
teraterm = Alt-b
putty = ctrl-break
securecrt = ctrl-break.
This is the same BREAK signal that allows password recovery on Cisco Routers?
I have been attempting the power cycle method but do not seem to be able to inter the break signal at the correct time (I am using securecrt), Here is where I am trying:
Booting kickstart image: bootflash:/n5000-uk9-kickstart.4.1.3.N2.1a.bin....

Jerry,
If you do not see the intitial config dialog, you will need to perform recovery.
The steps are outlined on this page:
http://www.cisco.com/en/US/docs/switches/datacenter/sw/password_recovery/nx_os_pw.html
Basically, you will need to be on the console and "break" into kickstar, then issue a new admin-password, and then continue booting.
Let us know if that document needs some clarification.

I follow the instruction, it go well until step 9.
Step 9 Display the bootflash: contents to locate the Cisco NX-OS software image file.
switch(boot)# dir bootflash:
It is nothing come out when I cmd dir bootflash: .I tried to input the nx-os with cmd below I know it had it in bootflash:
switch(boot) # load bootflash:n3000-uk9.6.0.2.U6.1.bin
but it does not work. I am stuck there.

Hi All,
I have the same issue.
I work on OS X Mountain Lion with USB-2-serial and iterm.
I have tried with ctrl+shift+b or ctrl+shift+alt+] but nothing to do, switch complete boot and prompt login.
Any idea on which short cut could I use on mac to access recovery mode?
Thanks
Regards

On OS X Mountain Lion. I gave up too. Was able to do it via VMware Fusion. If you don't have vmware fusion just find a windows laptop or try virtualbox with windows.

Hey guys,
Use Ctrl+C option. This is the break key for Nexus 5010 switch
I faced the same issue.
I reboot the switch and than I gave Ctrl+C key for break and switch comes in switch
I hope this will resolve your issue
