12. Upgrading RSM Firmware
When new, improved versions of the RSM firmware become available, the "Upgrade
Firmware" function can be used to update the unit. Updates can be uploaded via FTP
or SFTP protocols.
Notes:
• The FTP/SFTP servers can only be started via the Text Interface.
• All other ports will remain active during the firmware upgrade procedure.
• If the upgrade includes new parameters or features not included in the
previous firmware version, these new parameters will be set to their default
values.
1. Obtain the update file. Firmware modifications can either be mailed to the customer
on a CDR, or downloaded from WTI. Place the upgrade CDR in your disk drive or
copy the file to your hard drive.
2. Access Text Interface command mode via Serial Port, Telnet or SSH client session,
using a username/password and port that permit Supervisor commands.
3. When the command prompt appears, type /UF and then press [Enter]. The RSM
will display a screen which offers the following options:
a) Start FTP/SFTP Servers and Save Parameters: To proceed with the
upgrade, while retaining user-defined parameters, type 1 and press [Enter].
All existing parameter settings will be restored when the upgrade is complete.
b) Start FTP/SFTP Servers and Default Parameters: To proceed with the
upgrade, and reset parameters to default settings, type 2 and press [Enter].
When the upgrade is complete, all parameters will be set to default values.
c) Abort Upload: To cancel the upgrade and return to the command prompt,
type 3 and press [Enter].
Note that if either option 1 or option 2 are selected, the RSM will start the receiving
servers and wait for an FTP/SFTP client to make a connection and upload a valid
firmware binary image.
4. To proceed with the upgrade, select either option 1 or option 2. The RSM will
display a message that indicates that the unit is waiting for data. Leave the current
Telnet/SSH client session connected at this time.
