Accessing c-class interconnect switch thru Onboard Administrator (OA) cli, not responding to ESC key

[chuckk281]

Terri had an issue with how the OA was handling keyboard inputs:

********************

Have a c-class 8/24c SAN switch where we need to press the <ESC> key while the switch is going through its POST. But it is not responding. Once the switch completes post and gets to a command line, it does respond to keystrokes (but we don't do a ESC because that is not a valid command from the switch cli).

Any suggestions?

Monty had some suggestions for Terri:

**********************

The Onboard Administrator uses STTY for the connect interconnect command. 

Have you tried two ESC keys (ESC ESC)?     

Another combination to try is CTRL [

Anyone else have some comments or advice for Terri?

Solution was found:

Brocade engineering has reproduced the issue; they state that the problem is that the 8/24c switch does not support flow control. They issued the following procedure as a workaround:

1. In an OA CLI session, enter connect interconnect x to connect to the serial screen for interconnect x.

2. Ctrl + Shift + _

3. Select Change settings .

4. Select Remote Port .

5. Select None for Flow Control.

6. In a separate CLI session, reset the interconnect. Resetting should also be possible via the Reset virtual button in the OA GUI.

7. In the first CLI session, hitting <ESC> during interconnect boot will now enter single-user mode.

At this point, you should be able to continue with the normal password reset procedure.
