i am trying to reset password for the Cisco Nexus 7010 chasis need ur help
i tried these commands and it didn't work

Step 1 Establish a terminal session on the console port of the active supervisor module.

Note If you are using a non-U.S. keymap, the key sequence that you need to press to generate the break sequence may not work. In this case, we recommend that you set your terminal to a U.S. keymap. You can enter Ctrl-C instead of Ctrl-] (right square bracket) due to keyboard mapping.
Step 2 If you use SSH or a terminal emulator to access the console port or you are recovering the password on a Cisco Nexus 5000 Series switch running Cisco NX-OS Release 4.0(0)N1(2a) or earlier releases, go to Step 6.

Step 3 If you use Telnet to access the console port, press Ctrl-] (right square bracket) to verify that it does not conflict with the Telnet escape sequence.

 switch login: Ctrl-]
If the Cisco NX-OS login prompt remains and the Telnet prompt does not appear, go to Step 6.

Step 4 If the Telnet prompt appears, change the Telnet escape sequence to a character sequence other than Ctrl-] (right square bracket). The following example shows how to set the Ctrl-\ as the escape key sequence in Microsoft Telnet:

 telnet> set escape ^\
 Escape Character is 'CTRL+\'
Step 5 Press Enter one or more times to return to the Cisco NX-OS login prompt.

 telnet> <Enter>
 switch login:
Step 6 Power cycle the device.

Step 7 Press Ctrl-] (right square bracket) from the console port session when the device begins the Cisco NX-OS software boot sequence to enter the switch(boot)# prompt mode. You need to press Ctrl-] (right square bracket) when you see that the system image is getting loaded.

Note For Cisco Nexus 5000 Series switches that run Cisco NX-OS 4.0(0)N1(2a) or earlier releases, use Ctrl-B (Ctrl+Shift+B) instead of the Ctrl-] (right square bracket).

Step 8 Reset the network administrator password.

 switch(boot)# configure terminal
 switch(boot-config)# admin-password <new password>
 WARNING! Remote Authentication for login through console has been
 switch(boot-config)# exit
Step 9 Display the bootflash: contents to locate the Cisco NX-OS software image file.

 switch(boot)# dir bootflash:
Step 10 Load the Cisco NX-OS system software image.

In the following example, the system image filename is nx-os.bin:

 switch(boot) # load bootflash:nx-os.bin
Step 11 Log in to the device using the new administrator password.

You're going to have to be more specific. How are you attempting to recover the password? There are a few steps to the process, which one did not give the correct results? Maybe you could post the session output so we can see what didn't work.

Hi there, i did recovered the password but the problem is right now on i/o module no matter where i connect the i/o module it light is flushing red

when i went to see module from console

access# show module 4

Mod  Ports  Module-Type                      Model              Status
---  -----  -------------------------------- ------------------ ------------
4    0      1000 Mbps Optical Ethernet Modul                    pwr-denied

it just shows the supervisor module powered up

do i need any configuration to resolve this issue  i went to Cisco website to find out more but they all about how to make sure tight the screws and make sure it properly connected to chassis

do u think there is anyway to configure each module ?

The problem was that I had two supervisor engines reunning at the same time, once we removed one we were able to reset the password. In regards to the power issue, we had to combine them instead of fail-over state. Thanks for your help.
