Abstract

Examples herein disclose an apparatus for securing or disengaging a blade server in an enclosure. The apparatus includes a worm gear and a cam gear. The worm gear includes a number of threads to interact with a number of teeth on the cam gear. The cam gear includes the number of teeth to interact with the number of threads and a latch. The latch rotates based on the number of threads interacting with the number of teeth such that the rotation secures or disengages the blade server from the enclosure.

First claim

We claim:

1. An apparatus that secures or disengages a blade server into an enclosure, the apparatus comprising:
a worm gear comprising:
a number of threads to interact with a number of teeth on a cam gear; and
a number of lobes of differing sizes, located on a bezel head of the worm pear, the number of lobes of differing sizes specific to the blade server;

the cam gear comprising:
the number of teeth to interact with the number of threads; and
a latch to rotate based on the interaction between the number of teeth and the number of threads such that the rotation of the latch secures or disengages the blade server from the enclosure; and

an insertion tool specific to the number of lobes, to interact with the number of lobes such that causes the number of threads to interact with the number of teeth.

2. The apparatus of claim 1 comprising:
the bezel head, coupled to the worm gear and located on a front side of the blade server, to receive the insertion tool for rotation of the latch.

3. The apparatus of claim 1 comprising:
a pin to secure and disengage the latch for installation and removal of the blade server latch based on the rotation of the latch.

4. The apparatus of claim 1 wherein the number of threads is threaded as a right hand worm to interact with the number of teeth on the cam gear.

5. The apparatus of claim 1 comprising:
a bushing guide to constrain the worm gear to a position.

6. A system comprising:
a blade server to secure into an enclosure;
a worm gear comprising:

a number of threads on a body of the worm gear;
a bezel head to rotate which causes a number of threads to interact with a number of teeth on a cam gear;
a number of lobes of varying sizes specific to the blade server;
an interface tool, corresponding to the number of lobes of varying sizes specific to the blade server, to cause the rotation of the bezel head; and
a cam gear comprising:
a number of teeth to interact with the number of threads based on the rotation of the bezel head; and
a latch to rotate, based on the interaction between the number of teeth and the number of threads, such that the rotation of the latch secures the blade server into the enclosure.

7. The system of claim 6 comprising:
a board comprising:
a pin to interact with the latch causing the latch to secure the server blade; and
a notch to allow rotation of the latch.

8. The system of claim 6 wherein the number of teeth are in a pattern on the cam gear to prevent overdriving the server blade into a back of the enclosure.
