session with that radio is reopened issue the command:
> version
and check that the radio is indeed executing the new version.
16. Repeat the previous two steps until all the radios are running the new firmware.
Note that the file downloads are executed with the network in full operation. The only downtime in
the network 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, and all its children, is typically less
than twenty seconds. When upgrading to an incompatible version, the downtime will be less than two
minutes.
5.4.3 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 7 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., vip01_05.dwn.
2. Initiate a Telnet session with the radio as described in section 7.
3. If the radio configuration has been password protected, you must first unlock the protection with
the command:
>
unlock enable-configuration= password
(when the configuration is unlocked, the radio prompt ends with the characters ‘#>. In locked
mode the prompt does not include the ‘#’ character).
4. Issue the command:
>directory
to view a list of files stored in Flash PROM as well as the available free space. Verify that there
is enough free space in flash PROM for the new file. The space required will be the size of the
vipNN_NN.dwn file divided by 2.5. If there is not enough space in Flash PROM delete one of
the program files to make up space (use command >delete filename).
5. Start the download process by typing:
>download-file destination=vipNN_NN method=inline
where NN_NN file is new version of software being installed.
6. The radio will return with the following:
“
Send the file ... if incomplete, end with a line with just a period ”
When you get this prompt, go to “Transfer-Send Text file…” in Hyperterminal and select the file
to be installed. The file must have a “.dwn” extension.
7. After the file is successfully installed issue the command:
>directory
to insure that the file has been loaded into memory.
