9. Upgrading the CMS-6R4 Firmware
When new, improved versions of the CMS-6R4 firmware become available,
the "Upgrade Firmware" function can be used to update the unit. Updates can
be installed via the Network Port, Internal Modem Port or Serial Port 1.
Notes:
• The upgrade procedure can only be performed via the Text Interface.
• The upgrade command (/UF) will only function when invoked at the
Network Port, Serial Port 1 or the Internal Modem Port (Port 7.)
• All other network ports will be disabled during the firmware
upgrade procedure.
• When the upgrade procedure is complete, parameters may be set to
their default states. Therefore, it is recommended to save previously
selected configuration parameters to an ASCII file (as described in
Section 8) before beginning this upgrade procedure.
• If the upgrade includes new parameters or features which were not
included in the previous firmware version, these new parameters
will be set to their default values.
• When the upgrade is performed via the Network Port, the CMS-6R4
will not default the IP Address, Subnet Mask, or Gateway Address.
This allows the Telnet connection to be easily reestablished after the
upgrade is complete.
1. Obtain the update file. Firmware modifications can either be mailed to
the customer on a CDROM, sent via email, or downloaded from WTI.
Copy the upgrade file to your hard drive and then proceed as follows.
2. Access the CMS-6R4 command mode using the Text Interface via either
the Network Port, Internal Modem Port (Port 7) or Port 1. If the password
prompt is displayed, key in a password that permits access to Supervisor
Level commands.
3. When the command prompt appears, type /UF and press [Enter]. The
CMS-6R4 will display a screen which offers the following options:
1. Continue Upload and Keep Current Parameters: All exisiting
parameter settings will be restored when the upgrade is complete
2. Continue Upload and Default the System: When the upgrade is
complete, all parameters will be set to default values.
3. Abort Upload: Cancels upgrade and returns to command prompt.
Key in number for the desired upload option and then press [Enter].
