Remote OCP NIC Locking Mechanism for Secure Chassis Access
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
OCP NIC networking devices in unsecure locations are vulnerable to theft and vandalism due to easy access and disconnection, and conventional security measures require opening the computing device chassis, negating their benefits.
Innovation Solution
A networking device security system with a locking element and actuator device in the chassis, controlled via a networking device security engine, allows secure connection and disconnection of OCP NIC devices without opening the chassis, using network commands for verification and actuation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a manual securing latch is provided in the chassis housing to secure the networking device, then security against theft and vandalism is improved, but the ease of operation deteriorates because the chassis must be opened to access and secure the device
Solution Approach 1:
An actuator device is introduced as an intermediary mechanism between the controller and the locking element. The actuator converts rotational motion from the locking element into linear motion that drives the securing latch, enabling automated securing through network commands without manual chassis access
Solution Approach 2:
The networking device itself participates in the securing process by providing verification information about its connection state. The controller uses this information to determine when to activate the actuator, allowing the system to self-regulate its security state based on device status
2Reliability
If the chassis is opened to manually latch the securing mechanism, then security is improved, but the time required for connection and disconnection increases
Solution Approach 1:
The manual mechanical operation of opening the chassis and manually latching the securing mechanism is replaced with an automated electromechanical system. The controller receives network commands and automatically actuates the actuator device to secure or release the locking element, eliminating the need for manual chassis access
Solution Approach 2:
The actuator device is pre-positioned and mechanically coupled to the locking element and securing latch. When activated by the controller, it immediately translates rotational motion of the locking element into the linear motion needed to engage or disengage the latch, enabling rapid automated securing without preliminary manual preparation
3Ease of operation
If the networking device is easily accessible from the outer surface for quick connection and disconnection, then ease of operation is improved, but vulnerability to theft and vandalism increases
Solution Approach 1:
The securing system transitions from a static manual latch to a dynamic automated mechanism. The locking element can rotate between locked and unlocked positions, and the actuator dynamically translates this rotation into linear motion to engage or disengage the securing latch, allowing the system to adapt its security state based on operational needs

AI summary
A networking device security system includes a chassis housing a networking device. A locking element is movably coupled to the chassis adjacent the networking device, and an actuator device in the chassis is configured to actuate the locking element. A networking device security subsystem in the chassis receives a networking device locking command via a network, verifies the networking device locking command and, in response, controls the actuator device to actuate the locking element into a locked orientation that prevents movement of the networking device relative to the chassis. Subsequently, the networking device security subsystem receives a networking device unlocking command via the network, verifies the networking device unlocking command and, in response, controls the actuator device to actuate the locking element into an unlocked orientation that does not prevent movement of the networking device relative to the chassis.
