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.
3. Press [Esc] to return to the Main Menu. Select item 3 "System
Functions". When the System Functions menu appears, type 7 and
press [Enter] to activate the Upload Firmware function.
4. 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.
2. 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.
3. 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.
4. Abort: The upgrade procedure will not be performed, and the
unit will return to the System Functions menu.
