If the new firmware is incompatible with the old one, the links to the remotes will not be
reestablished. In this case, after 60 seconds, the remote radio will reboot. They will then load the
new firmware and be able to reestablish the links with the hub.
12. Wait at least ten seconds from the moment you entered the reboot command, then press <CR>.
Econsole automatically attempts to reconnect to the same radio. Once a new session with that
radio is reopened issue the command:
> version
and check that the radio is indeed executing the new version.
13. Depress the “F4” key to log-off the session with the hub radio. “Econ” displays the list of all
radios from the initial discovery phase. Select a different radio and issue the command:
>version
and check if that radio is running the new or old version. If the radio is already running the new
version repeat this step with the next radio. Otherwise perform the next step.
14. If the radio is running the old version issue the command:
>reboot
Wait at least ten seconds for the radio to perform its start up code and re-establish the link. Then
press <CR>. Econsole automatically attempts to reconnect to the same radio again. Once a new
session with that radio is reopened issue the command:
>version
and check that the radio is indeed executing the new version.
Note that the file downloads are executed with the link in full operation. The only downtime in the
link occurs when the radios are rebooting. The radio configuration is kept intact when a new version
is started. The downtime for the radio being restarted, is typically less than twenty seconds. When
upgrading to an incompatible version, the downtime will be slightly over one minute.
3.3.3 Installing new firmware using Telnet
Telnet is a protocol that allows you to conduct a remote radio command session from a local host.
The radio must have been pre-configured with an IP address and be reachable, over the network, from
the local host. Refer to section 5 for details on how to configure a radio IP address and initiate a
Telnet session. The Telnet terminal emulation must have the capability of sending an ASCII file to
the remote machine. The following description assumes you are using Hyperterminal as the local
Telnet terminal emulation.
1. Verify that the new software is available in the local machine. The download software for
upgrade via Telnet must have a “.dwn” extension, e.g., pmp03_25.dwn.
2. Initiate a Telnet session with the radio as described in section 5.
3. If the radio configuration has been password protected, you must first unlock the protection with
the command:
>unlock enable-configuration=password
