Cisco Unity New Install on an MCS 7835: Dongle is Not Recognized

Document ID: 7273

Updated: Feb 02, 2006



Cisco Unity licensing is stored on a SentinelSuperPro security key (dongle). The keys are hardware devices that plug into the parallel or USB port on the Unity machine. To successfully install Cisco Unity software, the system must detect the dongle.

Components Used

The information in this document is based on all versions of Cisco Unity for Exchange.

The information presented in this document was created from devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If you are working in a live network, ensure that you understand the potential impact of any command before using it.


The Cisco Unity installation will fail if the system does not detect the dongle. This document provides two scenarios in which the system may not detect the dongle. These scenarios apply only when using a parallel port dongle and and MCS-7835 or Compaq ProLiant 1850R server.


The solutions to this problem are explained in detail below.

Forcing an IRQ

The MCS-7835 machine does not assign an Interrupt Request (IRQ) to LPT1. By default, it assigns an IRQ only to the I/O of 378. By manually forcing an IRQ (usually 7) to LPT1, the system detects the dongle.

To force the parallel port to an IRQ, the BIOS must be the most recent, according to Cisco. To check the BIOS version, perform the following steps.

  1. Go to a command prompt and type debug, then press Enter.

  2. Type D F000:FFF5 and press Enter.

  3. The BIOS date displays in the right-hand corner. Compare this information with the BIOS update information, called ROMPaq.

    1. Go to

      The Compaq search window appears.


    2. In the Enter a product name/number search box, enter the ProLiant DL380 and click Search. Then, choose the appropriate server from the list. In this example, the HP ProLiant DL380 G4 Server is chosen.

    3. Click on your operating system. (For this example, Microsoft Windows Server 2008 W32 was selected for the operating system.)


    4. Click the BIOS - System ROM or scroll down to the BIOS - System ROM information and view the current version for the Online ROM Flash component for Windows - HP ProLiant DL380 G4 (P51) Server entry.

      The following example shows the BIOS date of 24 Jan 2008.


    5. You now need to force the parallel port to an IRQ.

  4. Go to Start > Programs > Administrative Tools > Computer Management.

  5. Under System Tools, select Device Manager.

  6. Select Ports (Com and LPT).

  7. Right-click on the printer port (by default LPT1).

  8. Select the Resources tab.

  9. Set the Settings Based On option field to a configuration which allows you to add an interrupt, either Basic configuration 0001 or Basic configuration 0003.

  10. Highlight Interrupt Request? and select the Change Setting button.

  11. Change the value to 07 (the standard interrupt for LPT1) and verify that no devices conflict with this setting.

  12. Select the Port Settings tab.

  13. Activate the Use any Interrupt Assigned to the Port check box.

  14. Activate the Enable Legacy Plug and Play Detection check box.

  15. Click OK.

Verifying the Setting

To verify the setting, perform the following steps.

  1. Restart the PC and press F10 during the startup process to enter the Setup/BIOS information screens.

  2. Go to System Config > Configure Hardware > View or Edit Details > Integrated Interface.

  3. Verify that the parallel port is set for IRQ 7.

Adding a PCI-based Parallel Port

A problem exists with the dongle when used on a PCI-based parallel port. To resolve this problem, perform the following steps.

  1. Go to the Windows Control Panel and write down the resource properties for the PCI parallel port.

    The actual icon in the Control Panel you use to display port properties depends on the version of Windows you are using. In some cases, a range rather than an absolute address is displayed. For example, D400-D407.

  2. Launch Setupx86.exe and select Functions > Configure > Add from the menu.

  3. Under the bus address, enter the address or the lower end of the range (D400) and make sure that the Use this Port option is not activated.

    Failure to deactivate the Use this Port option may result in an endless loop of messages such as Install the Board Drivers and Port Conflict.

  4. Reboot the PC and launch Setupx86.exe.

  5. Select Functions > Configure > Edit from the menu and activate the Use this Port option.

  6. Complete the editing and exit the setup program.
