16.1.7. Upload Firmware


This function is used to upload NetLink II firmware updates.  Updates can be uploaded to the NetLink II via modem, Telnet, Console Port or SFTP client. To upload firmware, proceed as follows:

1                     Obtain the update file.  Firmware modifications can either be mailed to the customer, or downloaded from WTI.  Place the disk or diskette in your drive and/or copy the file to your hard drive.

2                     This upload procedure may erase all parameters from flash memory and will clear stored data from the unit. Therefore, it is recommended to retrieve stored data and download parameters before beginning this procedure.


a) Access command mode. Poll the unit to retrieve all stored data as described in Section 14.

b) Use the Download Parameters function (see Section 14.2) to save all user- defined parameters.

1                     Press [Esc] to return to the Main Menu. Select item 3 "System Functions". When the System Functions menu appears, type 7and press [Enter] to activate the Upload Firmware function.

2                     NetLink II will display a screen which offers four options:


1. Only Keep IP Parameters: The NetLink II operating firmware will be updated, all stored data will be erased and all parameters except the following will be cleared:

•                      Network Port Parameters:  IP Address, Subnet Mask, Gateway Address, IP Security (Host Allow, Host Deny), Telnet Access, SSH Access and SNMP Access.

•                      System Parameters:  NTP Addresses and Time Zone.


1                     Keep All Parameters: The operating firmware will be updated, and all existing user-defined parameters and stored data will be retained. Any new parameters added by the update will be set to default values.

2                     Start SFTP Session and Wait for Uploaded File: The operating firmware will be updated via an SFTP connection, and all existing user-defined parameters and stored data will be retained.  Any new parameters added by the update will be set to default values.

3                     Abort: The upgrade procedure will not be performed, and the unit will return to the System Functions menu.



•                      When Items 1 or 2 are selected, NetLink will immediately begin the upgrade procedure without displaying a "Sure" prompt.

•                      Access to NetLink II Command Mode will be blocked during the firmware upgrade procedure.


5. Transfer the update file to the NetLink II unit.

a) If Items 1 or 2 have been selected, use your communication program's upload function to transfer the update file to the NetLink II unit via modem, Telnet or the Console Port.  Select Binary file format, and then specify the filename and directory location for the firmware upgrade file.

b) If Item 3 has been selected, use your SFTP client to transfer the update file to the NetLink II unit.

Note: The Upload function will time-out after one minute of inactivity.  If the function times out, reselect the desired upgrade option (type 1, 2, or 3), and press [Enter] to continue, or type 4and press [Enter] to abort.


1                     If the upload is successful, NetLink II will install the new firmware and then reboot itself.

2                     Incomplete Upload: If the upload is interrupted, times-out, or if the file is corrupted during transfer, NetLink II will display an error message, and then return to the Upload Firmware menu. To proceed, re-enter the desired upgrade option (type 1, 2, or 3) and then press [Enter]. To abort, type 3and then press [Enter].


When firmware upgrades are available, WTI will provide the necessary files via download or mail. At that time, an updated User's Guide or addendum will also be available.
