Resetting Passwords/Reformatting Flash

Print version (268 KB PDF)

These instructions can be used to recover a Tenor AS, AF, AX, BX, or DX whose password has been lost or forgotten. Instructions are also provided for reformatting a Tenor's flash memory.

Requirements

Before you begin this procedure, you should be prepared with the following items:

• Tenor unit
  Note: The Tenor AF does not have a Reset button. Where there are references in these instructions to pushing the Reset button, if you have a Tenor AF you should press and hold the Diag button while you unplug and then replug the power cord.
• Windows PC
• Terminal emulation software
• RS-232 cable (check your hardware manual for cabling instructions)

If you are going to reformat the Tenor's flash memory, you will also need the following:

• License.dat file obtained from Quintum (see Reformat Flash for instructions)
• Latest firmware for your Tenor (downloaded from the Quintum Support website)

Password Recovery

The recovery procedures are different depending on your firmware version:

• P103 and above - follow the steps in the next section
• P102 and below - skip to the Reformat Flash instructions

Note: This procedure will wipe out any configuration you have done on the Tenor.

Firmware Version P103 and Above

If your unit is running P103 or higher firmware, you can reset the password from the console port upon reboot. Connect to your unit via a serial connection, and power cycle your unit. When prompted to do so, press 'r' to restore factory defaults on the unit. This changes your password back to the default (admin). Note that all configurations on the Tenor will be lost.

To start this procedure, you need to connect to your Tenor via an RS-232 serial connection, and then establish a terminal emulation session using your preferred software. The configuration should be 38400 bps, 8 data bits, no parity, 1 stop bit, no flow control.

As an example, follow these steps to start a HyperTerminal session (Windows native terminal emulation software):

1. Open the HyperTerminal program on your Windows PC. Click on Start > Programs > Accessories > Communications > HyperTerminal.
2. In the Name field, enter a name for this connection (such as Tenor) and click OK.
3. In the Connect Using field, select Direct Connect to Com x (using the Com port number to which you have connected the serial cable), and click OK.
4. Set the Port Settings as shown below and click OK.
   • Bits per Second - 38400
   • Data Bits - 8
   • Parity - None
   • Stop Bits - 1
   • Flow Control - None

HyperTerminal COM Port Properties

You are now ready to reset your password. Please note that you will lose all configuration settings on your Tenor.

1. Locate the Reset button on the Tenor. On the analog units it is located on the back, and on digital units it is located on the front. (For Tenor AF, see Note.)
2. On the other units, push and release the Reset button to reboot the Tenor. During the boot sequence, you will be prompted with the following string:

   >> WITHIN 4 SECONDS, PRESS 'r' FOR FACTORY DEFAULTS OR 'i' TO SET STATIC IP <<

   When prompted with this string, press 'r'. As shown below, you will then be prompted to confirm.

   PRESS 'y' WITHIN 4 SECONDS TO CONFIRM.

   Press 'y' to confirm you wish to set the Tenor to factory defaults. You will see the following confirmation message:

   FACTORY DEFAULTS RESTORED.

Your Tenor password and configurations are now in a default state. You may now log in with the default password, "admin".

Note: We encourage you to change your password to something unique and store it in a safe place. Please see this Help topic on how to change your Quintum password.

Firmware Version P102 and Below
