Abstract

While the use of a carrier lever permits easy removal of a component mounted in the carrier from a subsystem, it may be necessary, for example for reasons of security, to positively prevent such removal. There is thus a requirement for an optional lock to be fitted to the carrier to prevent the carrier from being removed from the subsystem. The requirements of the lock are that it should be capable of being added to the carrier at the customer's location and be removable by the customer at a later stage.

Carrier Lock for Computer Subsystems

      While the use of a carrier lever permits easy removal of a
component mounted in the carrier from a subsystem, it may be
necessary, for example for reasons of security, to positively prevent
such removal.  There is thus a requirement for an optional lock to be
fitted to the carrier to prevent the carrier from being removed from
the subsystem.  The requirements of the lock are that it should be
capable of being added to the carrier at the customer's location and
be removable by the customer at a later stage.

      The requirement can be met by using a moulded plug and lock
assembly which can be inserted into the carrier lever and locked.
Once in the lever the plug prevents the user from accessing the
release catch thus rendering the carrier locked.  The lock assembly
consists of a purposely designed moulding fitted with a standard
radial lock to provide a recognised level of security.  The plug and
lock assembly are easily removed from the carrier lever by use of an
authorised key.  The solution described provides a feature which may
be readily retrofitted by the customer without the need to remove the
carrier from the subsystem.  The action of fitting the lock is also a
soft action unlikely to disturb eg a file operation within the
carrier within the subsystem.
