Authentication Button
The Authentication button is used as a security measure to deny some degree of access to those who cannot
prove physical access to the BroadNAS. The main idea here is that the primary security threat to a typical home
BroadNAS is over the network from anonymous hackers, not from anyone inside the home. Passwords are
good for protecting against intruders, but may have some disadvantages.
Example: A typical BroadNAS user might need to access the configuration interface only about once a
year, making a password hard to remember. This could make the user have to call tech support or use an
obvious password like password or BroadNAS, which would make the system easy prey to anyone on the
network connecting to the BroadNAS. As a supplement or alternative, the user can choose to allow
configuration access only to those who can press the button to prove they are in the house.
Note: This kind of physical authentication is not a replacement for passwords, and is another option
that can be used with or instead of passwords, as the user chooses. It also helps avoid the initial setup
security problem of deciding what the password should be when the system arrives. If it is the same
for every BroadNAS or the system is not protected by a password until the user explicitly sets one,
systems are vulnerable until the users explicitly configure them. This is a particular problem for a
BroadNAS since all configuration is done over the network, unlike a PC where the initial configuration
can be required to be done at the keyboard of that PC and not over the network.
Soft Power Button
The Soft Power button on the front of the box is a cleaner way to shut down power than the Hard Power switch
on the back. For details, see
Power Indicator Light
The Power Indicator light shows whether or not the BroadNAS is turned on. If the light is on, then the system
is turned on.
Network Connectivity Light
The Network Connectivity light indicates whether or not there is a good physical connection to the network. If
the light is not on, then the BroadNAS is unable to communicate on the network port at all. This typically means
that a cable is either not connected, or connected to a device that is turned off or not working correctly.
Note: If the light is on, that does not necessarily mean that all is right with the network—it just means
that the basic communication link is connected. The light might be on even if the BroadNAS cannot
successfully serve files, such as if its network configuration is not compatible with that of the network
to which it is connected.
