File Loading Procedure

To load software files:
1 Verify that you have IP connectivity from your computer to the NPU (either the
MGMT or the DATA port). To verify the connection, ping the unit's IP address
and verify that PING replies are being received.
2 To perform the upgrade, use a DOS TFTP utility with the following syntax:
tftp -i hostaddress put sourcefile
where -i stands for binary mode and hostaddress 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.
3 Following a successful completion of the file loading process, the Transfer
successful DOS message is displayed.
4 The unit decompresses the loaded file and checks the integrity of the new
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.
5 Check that the loaded versions exist in the unit:
To view the current NPU/ BST SW Versions in the unit:
Select Unit Control>SW Versions Control>Show Versions .
To view the current SU/AU SW files in NPU/ BST:
Select SU/AU>SW Files in NPU/ BST>Show Files .
