Solved: 3515 MCU - Password recovery procedure using null cable

Juan Carlos Arias Perez · ‎02-03-2015

Hello, I have a IPVC-3515-MCU12 that need a password recovery, I found that I need to use the terminal cable that ships with the unit or a null cable, I don't have the original cable so I'm looking to fix it with null cable.

I tried with a serial cable USB to DB-9 and it doesn't work, can someone help me on what it's the correct connection for null cable.

Regards,

Juan Carlos Arias

HI Juan,

Try with entering the following command: modifyTargetDevice and press Enter. See if that will provide you with the menu options.

Hi Juan,

Make sure you configure hyperterminal settings as follows:

Procedure:

Connect the RS-232 terminal cable to the PC terminal on MCU unit.
Connect the power cable.
Start the terminal emulation application on the PC.
Set the communication settings in the terminal emulation application on the PC as follows:
- Baud rate: 57600 for Audio blade (9600 for Video blade is used in MP7, while 57600 for Video blade is used in MP8.0/8.5)
- Data bits: 8
- Parity: None
- Stop bits: 1
- Flow control: None
Click OK.
Restart the MCU to get the initial menu during boot process.

See if that will connect you properly. Once you are in, and access the main menu options, to change the password follow these instructions:

Press any key as soon as you see the message "Press any key to start configuration" on the screen. You only have six seconds.

Press any key to start configuration...

Main menu

N: Configure default network port values

P: Change the configuration software password

S: Configure network security mode

A: Advanced configuration menu

Q: Quit

Select:

Enter P.
Enter the name "admin."
Enter the password that you want to use.
Enter Q to save your changes and to allow the Audio Blade to complete the boot process.

I hope this will help.

Hello Dejan, thanks for your help, I still have some problem, when I start MCU the message "Press any key to start configuration" never appears, there is down counter that does the same if press or not any key, the Network Configuration menu never appears, I can only see the boot events. Something like this:

Hello Dejan, I could change the password, but how do I configure MCU 3515 appliance? I mean which commands use to configure it?? There is no GUI access??

dpetrovi · ‎02-05-2015

Hi Juan,

With what product are you using this 3515 device? As a stand alone or integrated with something else. I am familiar with this product only if used as Hardware Media Server for Cisco Unified MeetingPlace product. And normally, with that kind of a firmware loaded, once you configure IP address, Subnet Mask, and Default Gateway on in the hyperterminal session and connect the device to the network, you should be able to access Web interface by going to the IP address of the device and login with admin credentials you've created.

However, if this is some different kind of integration, I may not be able to help you.

Juan Carlos Arias Perez · ‎02-05-2015

Hello Dejan,

Integrated with CUCM for video conference. On a browser I input IP address and have no access, no page loaded.

I appreciate your help and if you have something else that could help me, it will be great,

Juan Carlos Arias

dpetrovi · ‎02-05-2015

Hi Juan,

For that piece, I would advise you to submit that specific questions to Unified Communications Application community group as they can help you with the actual CUCM integration and configuration. They should know what firmware should be loaded and how to configure it.

Unfortunately, this community is only for Cisco WebEx Meetings Server (that doesn't use 3515 devices) and Cisco Unified MeetingPlace product that does use it as Hardware Media Server but with a very specific firmware loaded.

Kind regards,

-Dejan

Hi Dejan, ok I'll do that, thanks for your time and help.

You can find all the configuration guides for the 3515 on the Cisco Web site - here's an example: http://www.cisco.com/c/en/us/td/docs/video/cuvc/5_6/mcu/3515/configuration/guide/cfg-guide-Wrapper.html

Hello Wayne, thanks for your link, but the problem before continue with this file, is that I can't access via GUI, it's not responding, and I'm looking how to restore it.

Wayne DeNardi · ‎02-05-2015

Have you followed all the steps in the "Setting Up Your Cisco Unified Videoconferencing 3515 MCU" section of the Admin guide: http://www.cisco.com/c/en/us/td/docs/video/cuvc/5_0/mcu/3515/administration/guide/1umcu50ag/setup.html

That section details how to configure all the IP settings for the MCU and the Video Processing Module from the command line. Note: the IP address of the VPM must be different than the IP address configured for the MCU. This section also describes how to set (or change) the web server port which may have been set previously to something other than one of the standard ports, hence why you are unable to access it with your browser.

Also, you mentioned you were just trying to access the device with the IP address in your browser. To get to the admin page you need to go to http://<ipaddress>/admin

Hello Wayne, I review again all the requirements and it seems to be right, but don't have access via GUI, I'll try openning a report on TAC.

You can find the pinout for the Cisco/Codian MCU cable here: cisco_telepresence_codian_serial_cable_pinout_kb_119.html

Note: Your question would be better placed in the TelePresence section of the forums where these devices are more actively discussed than in the Conferencing section you've posted in - I'd suggest, if the above hasn't answered your query, that you move your discussion over there.
