Apple Workgroup Server 9150/120 - Manual (Page 21)

By itself, a locking cable cannot prevent unauthorized use of the server, but it
can prevent the server (and its peripheral devices if they are also secured by
locking cables) from being removed.
In combination with the key lock switch, a locking cable ensures that the system
is secure physically and that only the person with the key can operate it locally.
Using the key lock switch
The key lock switch is a physical lock on the front panel of the Workgroup
Server 9150. When you turn the key to the “secure” position, the Apple
Desktop Bus (ADB) devices (that is, the keyboard and mouse) and floppy
disk drive become inoperable. This means that the server cannot be operated
locally; the server can be operated only by special (remote-access) software
that makes it possible to control the server from another computer on the
network. See “Turning the Server On” later in this chapter for more details
about using the key lock switch.
