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"

Jon,

I have tried the steps you metioned in the document.  it seems the break command is not working.

I have tried the Ctrl ] and the Cntrl B, niether seem to be getting me to the switch (boot) > prompt

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.

John Gill

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 mode.

I hope this will resolve your issue
