Locking the password
The lock feature is designed to prevent
unauthorized changes to the configuration –
even in cases where the unit is mounted in an
insecure area. Setting lock on has the following
results:
• The password cannot be changed.
• The Reset unit to default feature is disabled
so that the unit cannot be reconfigured even
with physical access.
• The backdoor password is disabled – Nokia
Technical support can normally recover a
unit when the password has been forgotten
using a backdoor password. When locked,
this is disabled.
• TFTP functions are disabled.
• Normal Learn mode is disabled. When in
learn mode the only difference compared to
Manual mode is that the serial port is
assigned to the command line monitor
instead of the Internet Access function.
The net effect of locking the unit is that it is
impossible to change the configuration of the
unit without knowledge of the configuration
password. This means that if the password is
lost or forgotten, the unit cannot be recovered
without physical repair at the factory. Such
repair is not covered by the warrantee.
Setting specific managers
The A032 can be configured so that only
specific workstations are allowed to access the
management functions. This is especially
important for TFTP protection.
The TFTP function (see page 103) allows you to
reconfigure and download firmware to the unit.
