This document describes the steps you need to do in order to perform a factory reset on a Digital Content Manager (DCM) device.
You need to perform a Cisco DCM Factory reset in case any of the following events occur:
Locked out of device (user and password credentials are not available)
On versions equal or higher than v8.5, D9900/D9901: If management IP address is not available, and IP config tool access is not enabled on the Cisco DCM.
Device is reused with an entirely different configuration
Warning: Before you perform a Cisco DCM factory reset, please take into account the following considerations: After performing a Factory restart, all configuration settings, network setting, licenses, and security settings are lost.
Note: Factory reset cannot be performed in versions lower than v8.5. If you require to factory reset your pre v8.5 DCM unit, please contact your Cisco Technical Assistance Center.
How to perform a Factory Reset on a Cisco DCM ?
Graphical User Interface GUI Factory Reset
Local Factory Reset D9900/D9901
Local Factory Reset D9902
Remote GUI Factory Reset
Restarting the System
The Cisco DCM, IP Video Gateway Card, or IP Audio Gateway can be restarted from a remote location using the Cisco DCM GUI.
Three different restart actions are available:
Warm restart (device, IP Video Gateway Card, or IP Audio Gateway Card) The device or card restarts with its previous settings.
Cold restart (device, Video Gateway Card, or IP Audio Gateway Card)—The device or card restarts and the previous configuration settings are lost. Performing a cold restart of the device does not remove the security settings, the network settings of the management interfaces of the Cisco DCM housing, and license file.
Factory restart (device only)—The device restarts and all previous settings (even the security settings and the network settings of the management ports of the Cisco DCM housing) and license file are lost. The device becomes in the state as when it leaves our assembly line.
Performing a cold or factory restart can only be done using the GUI when you are logged on to the DCM with a GUI account belonging to the administrators security group. Navigate to Cisco DCM GUI > Help > Maintenance > Reboot, select the desired action: Warm, Cold or Factory.
Warning: Be aware that your Cisco DCM can become inaccessible over the network, after a GUI factory reset [default IP address] and may require an on-site intervention.
It is recommended to have a copy of the Cisco DCM license file and settings file in a secure place before performing a factory reset.
In a situation where you have no more GUI access, you may retrieve the configuration from the device, by executing the available tool on all Software releases, located under the tools directory.
Local Factory Reset D9900/D9901
A factory restart can also be done by restarting the Cisco DCM (cold or warm restart or by powering up the device) while the Cisco DCM hardware key (with pin 1 and 4 connected to pin 6) is plugged in into the Input/Output (I/O) connector of the Cisco DCM. When the Cisco DCM hardware key is plugged in, this icon is displayed in the GUI header, as shown in the image.
Local Factory Reset D9902
A factory restart removes the license file and all settings from the Cisco DCM, even the security and network settings. It can be done via the Cisco DCM GUI as explained earlier, or via a console connection using a personal computer and a serial terminal emulator program.
Connect a PC to the rear USB connector of the Cisco DCM with a USB to mini USB cable, open a terminal emulator (HyperTerminal, Tera Term, PuTTy), and configure communication: Baud rate: 38,400/Data 8-bit/Parity-None/Stop-1 bit/Flow control-None.
If the Console start up screen appears, perform a factory reset.
Change IP address.
Disable the GUI.
Start a shell.
Perform a Factory Reset.
Enable IPsec/Security Bypass.
After a Factory Reset
After performing a factory restart on a Cisco DCM, the management ports are provided with default network settings. These default IP settings can be found in your Cisco DCM System Guide. Alternatively, you can contact Cisco TAC for assistance.
Lower than v8.5
There is no option for a factory reset in versions lower than v8.5, unless performed by Cisco TAC personnel. When the DCM leaves the factory a number of default GUI and Operating System (OS) accounts will be created by the system.
Please consult your Cisco DCM System Guide for default GUI Login account credentials. Alternatively, you can contact Cisco TAC (Technical Assistance Center) for assistance.
You can change your Cisco DCM's management IP address via the IP Config Tool, which is by default enabled in versions lower than v8.5.
Best practice: Once you're logged in to your DCM with the default administrator account, it is recommended that you remove all other GUI and OS default created accounts, and generate your own with safe credentials.
v8.5 or higher
Important: After a Factory restart, an initial security setup must be done, as no permanent default GUI or OS accounts are be created.
Please consult your Cisco DCM System Guide for default temporary GUI Login account credentials.
During the initial security setup, at least one GUI account belonging to the Administrator security group and at least one Operating System account must be created.
When a D9902 leaves the assembly line or after a factory reset, its GUI is disabled and the management ports are provided with default network settings.
Before a Cisco DCM can participate in a network, its GUI must be enabled and at least one of the management ports must be configured with the correct network settings.
Enabling and disabling the GUI can be done by selecting the  option on the console menu
You can enter  on Console start screen, in order to assign new IP addresses to the Gigabit Ethernet (GbE) ports of a Cisco DCM housing
What about lost Licenses during Factory reset?
You can use the Cisco Product License Registration tool to retrieve a DCM license file via the World Wide Web and a standard web browser. After submitting the equipment's device Host ID, Product Authorization Key (PAK), and device validation key, a license file is returned by email or can be downloaded.
The licensing portal is accessible by entering the following URL in your web browser:
After receiving the license file by email, the corresponding licenses can be enabled by uploading this file via Cisco DCM GUI.
The device Host ID can be found on the Licenses page of the Cisco DCM GUI. To open the Licenses page, navigate to the Cisco DCM GUI Menu > Configuration > License
To install the license on the Cisco DCM Licenses page, click Browse. The file upload dialog box appears. Click Open. Select the file and click Update and OK. It takes about 15 seconds before the new license becomes active. You can click on the Reload button for faster visualization.
