rivial File Transfer Protocol (TFTP)
The ASI-R supports changes to the resident software and firmware by means of the
Trivial File Transfer Protocol (TFTP). This enables changes to be made remotely via the
LAN interface. It is recommended to use Solarwinds TFTP server application (available
at
http://support.solarwinds.net/updates/SelectProgramFree.cfm
).
To modify the software and/or firmware, use the following procedures:
Configure the server as follows:
a)
File
!
Configuration
!
Select the ‘
TFTP Root Directory
’. Set up the location
of the ASI-R files.
b)
File
!
Configuration
!
Select the ‘
Security
’ tab and make sure ‘
Transmit and
Receive
’ are selected.
c) Save
configuration.
The server is now configured for the file transfer process.
IMPORTANT
Because the ASI-R stops processing data traffic during the
download process, it is recommended that this upgrade procedure
be performed during scheduled network down time.
Do
NOT
remove power from the unit during the download process.
To modify code via Telnet:
Step
Procedure
1
Start up Solarwinds TFTP server – ensure configuration as described
previously.
2
Ensure that the code provided by CEFD is located in the TFTP Root
directory.
3
Start up Telnet client and initiate a session with the ASI-R as described
in the Telnet Interface section.
4 Select
‘
A
’ for Administration.
5 Select
‘
D
’ for Download.
6 Enter
‘
1
’ for Application code or ‘
2
’ for FPGA code (the user will be
directed to select
Application
or
FPGA
code in the download
instructions provided by CEFD when new code is provided).
7
Enter the IP address of the TFTP server and wait for the message
“
Upgrade complete. Press any key to continue.
”
This code modification process can also be conducted via the Web Interface, under the
Administration page, or the Terminal Interface under the Main Menu.
Under heavy traffic conditions, the TFTP transfer may take several
minutes. The transfer process reported by Solarwinds may show greater
than 100% transferred, but this is a normal condition. Be patient and
allow the transfer to take place.
