File Loading Procedure

To load software files:
Verify that you have IP connectivity from your computer to the NPU (either the
1
MGMT or the DATA port). To verify the connection, ping the unit's IP address
and verify that PING replies are being received.
To perform the upgrade, use a DOS TFTP utility with the following syntax:
2
tftp i hostaddress put sourcefile
where -i stands for binary mode and host address is the IP address of the unit
to be upgraded (NPU/ BST ). The put command instructs the PC client to send
a file to the hostaddress. sourcefile is the name of the SW file in the PC Client.
For example, to load the file npu_2_0_1_15 to the NPU whose IP address is
172.17.31.215, use the following command:
tftp -i 172.17.31.215 put npu_2_0_1_15
NOTE
It is recommended to upgrade all system elements with the latest software version. Nevertheless, it
is possible to upgrade each unit separately and independently.
Following a successful completion of the file loading process, the Transfer
3
successful DOS message is displayed.
The unit decompresses the loaded file and checks the integrity of the new
4
version. The new version replaces the previous shadow version only after
verification. If verification tests fail, the loaded version will be rejected. The
unit will reject a file if either the file name or the version number matches the
current Main versions.
Check that the loaded versions exist in the unit:

To view the current NPU/ BST SW Versions in the unit:
