General
When you receive the P113F, it's on-board agent comes pre-loaded with fully
functioning software. You should make sure that all units contain the latest
available software.
You must first upgrade the P110 NMA with the latest software version before
upgrading Switches.
The on-board agent software is stored in flash memory, and can be upgraded via
software download using the TFTP protocol.
In the on-board agent the flash memory contains two independent software
versions: the "Basic" and the "Application" version. The Application version is the
one that the P113F will use in normal operation. If the Application version is found
to be faulty, the Basic version will be used instead.
Caution: Download the Basic version only when the new Application version is
working correctly. This will ensure that if there is a problem with the application
version, the agent will be able to switch to a valid Basic version.
The TFTP Process
The agent software file should be placed on a computer that can be anywhere on
the network. During the TFTP process, the computer acts as the Server and the
agent as the Client. From the Terminal, the user configures the agent with the IP
address of the TFTP server, the file name to be downloaded, and the download
destination bank. The Agent then gets the specified file from the server.
During the download process the user can monitor the process status parameters
by using the Monitor Software Download Process sub menuCajunView. The agent
remains fully functioning during the download process. At the end of a successful
download, the whole switch stack resets automatically.
Software Download Procedure
Before starting the download procedure, do the following:
1. Ensure that the supplied agent software file resides on a computer with TFTP
server capabilities.
2. Ensure that the file is accessible to the agent. Contact the agent from the TFTP
server by typing ping <ip_address_of_agent>
